+  Set tabs to 4 for best viewing.
+  
+  Latest version of ADODB is available at http://php.weblogs.com/adodb
+  ======================================================================
+  
+ This file provides PHP4 session management using the ADODB database
+wrapper library.
+ 
+ Example
+ =======
+ 
+ 	GLOBAL $HTTP_SESSION_VARS;
+	include('adodb.inc.php');
+	include('adodb-session.php');
+	session_start();
+	session_register('AVAR');
+	$HTTP_SESSION_VARS['AVAR'] += 1;
+	print "<p>\$HTTP_SESSION_VARS['AVAR']={$HTTP_SESSION_VARS['AVAR']}</p>";
+
+ 
+ Installation
+ ============
+ 1. Create a new database in MySQL or Access "sessions" like
+so:
+ 
+  create table sessions (
+       SESSKEY char(32) not null,
+       EXPIRY int(11) unsigned not null,
+       DATA text not null,
+      primary key (sesskey)
+  );
+  
+  2. Then define the following parameters in this file:
+  	$ADODB_SESSION_DRIVER='database driver, eg. mysql or ibase';
+	$ADODB_SESSION_CONNECT='server to connect to';
+	$ADODB_SESSION_USER ='user';
+	$ADODB_SESSION_PWD ='password';
+	$ADODB_SESSION_DB ='database';
+	$ADODB_SESSION_TBL = 'sessions'
+	
+  3. Recommended is PHP 4.0.2 or later. There are documented
+session bugs in 
+     earlier versions of PHP.

+  
+  Latest version of ADODB is available at http://php.weblogs.com/adodb
+  ======================================================================
+  
+ This file provides PHP4 session management using the ADODB database
+wrapper library.
+ 
+ Example
+ =======
+ 
+ 	GLOBAL $HTTP_SESSION_VARS;
+	include('adodb.inc.php');
+	include('adodb-session.php');
+	session_start();
+	session_register('AVAR');
+	$HTTP_SESSION_VARS['AVAR'] += 1;
+	print "<p>\$HTTP_SESSION_VARS['AVAR']={$HTTP_SESSION_VARS['AVAR']}</p>";
+
+ 
+ Installation
+ ============
+ 1. Create a new database in MySQL or Access "sessions" like
+so:
+ 
+  create table sessions (
+       SESSKEY char(32) not null,
+       EXPIRY int(11) unsigned not null,
+       DATA text not null,
+      primary key (sesskey)
+  );
+  
+  2. Then define the following parameters in this file:
+  	$ADODB_SESSION_DRIVER='database driver, eg. mysql or ibase';
+	$ADODB_SESSION_CONNECT='server to connect to';
+	$ADODB_SESSION_USER ='user';
+	$ADODB_SESSION_PWD ='password';
+	$ADODB_SESSION_DB ='database';
+	$ADODB_SESSION_TBL = 'sessions'
+	
+  3. Recommended is PHP 4.0.2 or later. There are documented
+session bugs in 
+     earlier versions of PHP.

+  DB2 data driver. Requires ODBC.
+ 
+From phpdb list:
+
+Hi Andrew,
+
+thanks a lot for your help. Today we discovered what
+our real problem was:
+
+After "playing" a little bit with the php-scripts that try
+to connect to the IBM DB2, we set the optional parameter
+Cursortype when calling odbc_pconnect(....).
+
+And the exciting thing: When we set the cursor type
+to SQL_CUR_USE_ODBC Cursor Type, then
+the whole query speed up from 1 till 10 seconds
+to 0.2 till 0.3 seconds for 100 records. Amazing!!!
+
+Therfore, PHP is just almost fast as calling the DB2
+from Servlets using JDBC (don't take too much care
+about the speed at whole: the database was on a
+completely other location, so the whole connection
+was made over a slow network connection).
+
+I hope this helps when other encounter the same
+problem when trying to connect to DB2 from
+PHP.
+
+Kind regards,
+Christian Szardenings
+
+2 Oct 2001
+Mark Newnham has discovered that the SQL_CUR_USE_ODBC is not supported by 
+IBM's DB2 ODBC driver, so this must be a 3rd party ODBC driver.
+
+From the IBM CLI Reference:
+
+SQL_ATTR_ODBC_CURSORS (DB2 CLI v5) 
+This connection attribute is defined by ODBC, but is not supported by DB2
+CLI. Any attempt to set or get this attribute will result in an SQLSTATE of
+HYC00 (Driver not capable). 
+
+A 32-bit option specifying how the Driver Manager uses the ODBC cursor
+library. 
+
+So I guess this means the message [above] was related to using a 3rd party
+odbc driver.

+NLS_Date_Format
+Allows you to use a date format other than the Oracle Lite default. When a literal
+character string appears where a date value is expected, the Oracle Lite database
+tests the string to see if it matches the formats of Oracle, SQL-92, or the value
+specified for this parameter in the POLITE.INI file. Setting this parameter also
+defines the default format used in the TO_CHAR or TO_DATE functions when no
+other format string is supplied.
+
+For Oracle the default is dd-mon-yy or dd-mon-yyyy, and for SQL-92 the default is
+yy-mm-dd or yyyy-mm-dd.
+
+Using 'RR' in the format forces two-digit years less than or equal to 49 to be
+interpreted as years in the 21st century (2000–2049), and years over 50 as years in
+the 20th century (1950–1999). Setting the RR format as the default for all two-digit
+year entries allows you to become year-2000 compliant. For example:
+NLS_DATE_FORMAT='RR-MM-DD'
+
+You can also modify the date format using the ALTER SESSION command.

+  21.02.2002 - Wade Johnson wade@wadejohnson.de
+               Extended ODBC class for Sybase SQLAnywhere.
+   1) Added support to retrieve the last row insert ID on tables with
+      primary key column using autoincrement function.
+
+   2) Added blob support.  Usage:
+         a) create blob variable on db server:
+
+        $dbconn->create_blobvar($blobVarName);
+
+      b) load blob var from file.  $filename must be complete path
+
+      $dbcon->load_blobvar_from_file($blobVarName, $filename);
+
+      c) Use the $blobVarName in SQL insert or update statement in the values
+      clause:
+
+        $recordSet = $dbconn->Execute('INSERT INTO tabname (idcol, blobcol) '
+        .
+       'VALUES (\'test\', ' . $blobVarName . ')');
+
+     instead of loading blob from a file, you can also load from 
+      an unformatted (raw) blob variable:
+      $dbcon->load_blobvar_from_var($blobVarName, $varName);
+
+      d) drop blob variable on db server to free up resources:
+      $dbconn->drop_blobvar($blobVarName);

+GNU LESSER GENERAL PUBLIC LICENSE
+Version 2.1, February 1999 
+ 
+Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+ 
+ 
+Preamble
+The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. 
+
+This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. 
+
+When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. 
+
+To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. 
+
+For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. 
+
+We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. 
+
+To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. 
+
+Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. 
+
+Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. 
+
+When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. 
+
+We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. 
+
+For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. 
+
+In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. 
+
+Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. 
+
+The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. 
+
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". 
+
+A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. 
+
+The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) 
+
+"Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. 
+
+Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 
+
+1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. 
+
+You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 
+
+2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: 
+
+
+a) The modified work must itself be a software library. 
+b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. 
+c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. 
+d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. 
+(For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.) 
+
+These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. 
+
+Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. 
+
+In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 
+
+3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. 
+
+Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. 
+
+This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 
+
+4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. 
+
+If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 
+
+5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. 
+
+However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. 
+
+When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. 
+
+If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) 
+
+Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 
+
+6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. 
+
+You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: 
+
+
+a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) 
+b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. 
+c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. 
+d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. 
+e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. 
+For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. 
+
+It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 
+
+7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: 
+
+
+a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. 
+b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 
+8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 
+
+9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 
+
+10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 
+
+11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. 
+
+If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. 
+
+It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. 
+
+This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 
+
+12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 
+
+13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. 
+
+Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 
+
+14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. 
+
+NO WARRANTY 
+
+15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 
+
+16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

+  </b></a><b><a href="#changes">Change Log</a></b><br>
+</p>
+<h2>Introduction<a name="intro"></a></h2>
+<p>PHP's database access functions are not standardised. This creates a need for 
+  a database class library to hide the differences between the different database 
+  API's (encapsulate the differences) so we can easily switch databases.</p>
+<p>We currently support MySQL, Oracle, Microsoft SQL Server, Sybase, Sybase SQL Anywhere, Informix, 
+  PostgreSQL, FrontBase,  Interbase (Firebird and Borland variants), Foxpro, Access, ADO and ODBC. We have had successful reports of connecting
+  to Progress and DB2 via ODBC. We hope more people 
+  will contribute drivers to support other databases.</p>
+<p>PHP4 supports session variables. You can store your session information using 
+  ADOdb for true portability and scalability. See ADOdb-session.php for more information.</p>
+<p>Also read <a href="http://php.weblogs.com/portable_sql">http://php.weblogs.com/portable_sql</a> 
+  (also available as tips_portable_sql.htm in the release) for tips on writing 
+  portable SQL.</p>
+<h2>Unique Features of ADOdb<a name="features"></a></h2>
+<ul>
+  <li><b>Easy for Windows programmers</b> to adapt to because many of the conventions 
+    are similar to Microsoft's ADO.</li>
+  <li>Unlike other PHP database classes which focus only on select statements, 
+    <b>we provide support code to handle inserts and updates which can be adapted 
+    to multiple databases quickly.</b> Methods are provided for date handling, 
+    string concatenation and string quoting characters for differing databases.</li>
+  <li>A<b> metatype system </b>is built in so that we can figure out that types 
+    such as CHAR, TEXT and STRING are equivalent in different databases.</li>
+  <li><b>Easy to port</b> because all the database dependant code are stored in 
+    stub functions. You do not need to port the core logic of the classes.</li>
+  <li><b>PHP4 session support</b>. See ADOdb-session.php.</li>
+</ul>
+<h2>How People are using ADOdb<a name="users"></a></h2>
+Here are some examples of how people are using ADOdb (for a much longer list, 
+visit <a href="http://php.weblogs.com/adodb-cool-applications">http://php.weblogs.com/ADOdb-cool-applications</a>): 
+<ul>
+<li><a href="http://phplens.com/">PhpLens</a> is a commercial data grid component that allows both cool Web designers and serious unshaved programmers to develop and maintain databases on the Web easily. Developed by the author of ADOdb.<p>
+
+<li><a href="http://www.interakt.ro/phakt/">PHAkt: PHP Extension for DreamWeaver Ultradev</a> allows you to script PHP in the popular Web page editor. Database handling provided by ADOdb.<p>
+
+<li><a href="http://www.andrew.cmu.edu/~rdanyliw/snort/snortacid.html">Analysis Console for Intrusion Databases</a> (ACID): PHP-based analysis engine to search and process a database of security incidents generated by security-related software such as IDSes and firewalls (e.g. Snort, ipchains). By Roman Danyliw.<p>
+
+<li><a href="http://www.postnuke.com/">PostNuke</a> is a very popular free content management
+ system and weblog system. It offers full CSS support, HTML 4.01 transitional compliance throughout, an advanced blocks system, and is fully multi-lingual enabled. <p>
+
+<li><a href=http://www.auto-net.no/easypublish.php?page=index&lang_id=2>EasyPublish CMS</a>  is another free content management system for managing information and integrated modules on your internet, intranet- and extranet-sites. From Norway.<p>
+
+<li><a href="http://nola.noguska.com/">NOLA</a> is a full featured accounting, inventory, and job tracking application. It is licensed under the GPL, and developed by Noguska.
+</ul><p>
+
+<h2>Feature Requests and Bug Reports<a name="bugs"></a></h2>
+<p>Feature requests and bug reports can be emailed to <a href="mailto:jlim#natsoft.com.my">jlim#natsoft.com.my</a> 
+  or posted to the ADOdb Help forums at <a href="http://phplens.com/lens/lensforum/topics.php?id=4">http://phplens.com/lens/lensforum/topics.php?id=4</a>.</p>
+<h2>Installation Guide<a name="install"></a></h2>
+<p>Make sure you are running PHP4.01pl2 or later (it uses require_once and include_once). 
+  Unpack all the files into a directory accessible by your webserver.</p>
+<p>To test, try modifying some of the tutorial examples. Make sure you customize 
+  the connection settings correctly. You can debug using:</p>
+<pre>&lt;?php
+	include('adodb/adodb.inc.php');
+	$db = <a href="#adonewconnection">ADONewConnection</a>($database);
+	$db->debug = true;
+	$db-><a href="#connect">Connect</a>($server, $user, $password, $database);
+	$rs = $db-><a href="#execute">Execute</a>('select * from some_small_table');
+   print &quot;&lt;pre&gt;&quot;;
+	print_r($rs-><a href="#getrows">GetRows</a>());
+   print &quot;&lt;/pre&gt;&quot;;
+?&gt;</pre>
+<h3>Code Initialization<a name="coding"></a></h3>
+<p>When running ADOdb, at least two files are loaded. First is adodb.inc.php, 
+ which contains all functions used by all database classes. The code specific 
+ to a particular database is in the ADOdb-????.inc.php file.</p>
+<p>For example, to connect to a mysql database:</p>
+<pre>
+include('/path/to/set/here/adodb.inc.php');
+$conn = &amp;ADONewConnection('mysql');
+</pre>
+<p>Whenever you need to connect to a database, you create a Connection object 
+  using the <a name="adonewconnection">ADONewConnection</a>($driver) function. 
+  NewADOConnection($driver) is an alternative name for the same function.</p>
+<p>At this point, you are not connected to the database. 
+You will use <code>$conn-><a href=#connect>Connect()</a></code> or 
+<code>$conn-><a href=#pconnect>PConnect()</a></code> to perform the actual connection.</p>
+<p>See the examples below in the Tutorial.</p>

+<h3>Example 1: Select Statement<a name="ex1"></a></h3>
+<p>Task: Connect to the Access Northwind DSN, display the first 2 columns 
+  of each row.</p>
+<p>In this example, we create a ADOConnection object, which represents the connection 
+ to the database. The connection is initiated with <a href="#pconnect"><font face="Courier New, Courier, mono">PConnect</font></a>, 
+ which is a persistent connection. Whenever we want to query the database, we 
+ call the <font face="Courier New, Courier, mono">ADOConnection.<a href="#execute">Execute</a>()</font> 
+ function. This returns an ADORecordSet object which is actually a cursor that 
+ holds the current row in the array <font face="Courier New, Courier, mono">fields[]</font>. 
+ We use <font face="Courier New, Courier, mono"><a href="#movenext">MoveNext</a>()</font> 
+ to move from row to row.</p>
+<p>NB: A useful function that is not used in this example is 
+<font face="Courier New, Courier, mono"><a href="#selectlimit">SelectLimit</a></font>, which
+allows us to limit the number of rows shown.

+<p>The $<font face="Courier New, Courier, mono">recordSet</font> returned stores 
+  the current row in the <font face="Courier New, Courier, mono">$recordSet-&gt;fields</font> 
+  array, indexed by column number (starting from zero). We use the <font face="Courier New, Courier, mono"><a href="#movenext">MoveNext</a>()</font> 
+  function to move to the next row. The <font face="Courier New, Courier, mono">EOF</font> 
+  property is set to true when end-of-file is reached. If an error occurs in Execute(), 
+  we return false instead of a recordset.</p>
+<p>The <code>$recordSet-&gt;fields[]</code> array is generated by the PHP database 
+  extension. Some database extensions only index by number and do not index the 
+  array by field name. To force indexing by name - that is associative arrays 
+  - use the $ADODB_FETCH_MODE global variable. Each recordset saves and uses whatever 
+  fetch mode was set when the recordset was created in Execute() or SelectLimit().
+<pre>
+	$ADODB_<b>FETCH_MODE</b> = ADODB_FETCH_NUM;
+	$rs1 = $db->Execute('select * from table');
+	$ADODB_<b>FETCH_MODE</b> = ADODB_FETCH_ASSOC;
+	$rs2 = $db->Execute('select * from table');
+	print_r($rs1->fields); # shows <i>array([0]=>'v0',[1] =>'v1')</i>
+	print_r($rs2->fields); # shows <i>array(['col1']=>'v0',['col2'] =>'v1')</i>
+</pre>
+<p>
+ </p>
+<p>To get the number of rows in the select statement, you can use <font face="Courier New, Courier, mono">$recordSet-&gt;<a href="#recordcount">RecordCount</a>()</font>. 
+ Note that it can return -1 if the number of rows returned cannot be determined.</p>
+<h3>Example 2: Advanced Select with Field Objects<a name="ex2"></a></h3>

+</font>
+?>
+</pre>
+<p>In this example, we check the field type of the second column using <font face="Courier New, Courier, mono"><a href="#fetchfield">FetchField</a>().</font> 
+ This returns an object with at least 3 fields.</p>
+<ul>
+ <li><b>name</b>: name of column</li>
+ <li> <b>type</b>: native field type of column</li>
+ <li> <b>max_length</b>: maximum length of field. Some databases such as MySQL 
+  do not return the maximum length of the field correctly. In these cases max_length 
+  will be set to -1.</li>
+</ul>
+<p>We then use <font face="Courier New, Courier, mono"><a href="#metatype">MetaType</a>()</font> 
+ to translate the native type to a <i>generic</i> type. Currently the following 
+ <i>generic</i> types are defined:</p>
+<ul>
+ <li><b>C</b>: character fields that should be shown in a &lt;input type=&quot;text&quot;&gt; 
+  tag.</li>
+ <li><b>X</b>: TeXt, large text fields that should be shown in a &lt;textarea&gt;</li>
+ <li><b>B</b>: Blobs, or Binary Large Objects. Typically images.
+ <li><b>D</b>: Date field</li>
+ <li><b>T</b>: Timestamp field</li>
+ <li><b>L</b>: Logical field (boolean or bit-field)</li>
+ <li><b>N</b>: Numeric field. Includes autoincrement, numeric, floating point, 
+  real and integer. </li>
+ <li><b>R</b>: Serial field. Includes serial, autoincrement integers. This works for selected databases. </li>
+</ul>
+<p>If the metatype is of type date or timestamp, then we print it using the user 
+ defined date format with <font face="Courier New, Courier, mono"><a href="#userdate">UserDate</a>(),</font> 
+ which converts the PHP SQL date string format to a user defined one. Another 
+ use for <font face="Courier New, Courier, mono"><a href="#metatype">MetaType</a>()</font> 
+ is data validation before doing an SQL insert or update.</p>
+<h3>Example 3: Inserting<a name="ex3"></a></h3>
+<p>Insert a row to the Orders table containing dates and strings that need to be quoted before they can be accepted by the database, eg: the single-quote in the word <i>John's</i>.</p>
+<pre>
+&lt;?
+<b>include</b>('adodb.inc.php');       # load code common to ADOdb

+$<font color="#660000">shipto</font> = <font color="#006600"><b>$conn-&gt;qstr</b></font>(&quot;<i>John's Old Shoppe</i>&quot;);
+
+$<font color="#660000">sql</font> = &quot;insert into orders (customerID,EmployeeID,OrderDate,ShipName) &quot;;
+$<font color="#660000">sql</font> .= &quot;values ('ANATR',2,&quot;.<b><font color="#006600">$conn-&gt;DBDate(</font>time()<font color="#006600">)</font></b><font color="#006600">.</font>&quot;,$<font color="#660000">shipto</font>)&quot;;

+	<b>print</b> 'error inserting: '.<font color="#336600"><b>$conn-&gt;ErrorMsg()</b></font>.'&lt;BR&gt;';
+&#125;
+?>
+</pre>
+<p>In this example, we see the advanced date and quote handling facilities of 
+  ADOdb. The unix timestamp (which is a long integer) is appropriately formated 
+  for Access with <font face="Courier New, Courier, mono"><a href="#dbdate">DBDate</a>()</font>, 
+  and the right escape character is used for quoting the <i>John's Old Shoppe</i>, 
+  which is<b> </b><i>John'<b>'</b>s Old Shoppe</i> and not PHP's default <i>John<b>'</b>s 
+  Old Shoppe</i> with <font face="Courier New, Courier, mono"><a href="#qstr">qstr</a>()</font>. 
+</p>
+<p>Observe the error-handling of the Execute statement. False is returned by<font face="Courier New, Courier, mono"> 
+ <a href="#execute">Execute</a>() </font>if an error occured. The error message 
+ for the last error that occurred is displayed in <font face="Courier New, Courier, mono"><a href="#errormsg">ErrorMsg</a>()</font>. 
+ Note: <i>php_track_errors</i> might have to be enabled for error messages to 
+ be saved.</p>
+<h3> Example 4: Debugging<a name="ex4"></a></h3>
+<pre>&lt;?
+<b>include</b>('adodb.inc.php');       # load code common to ADOdb
+$<font color="#663300">conn</font> = &amp;ADONewConnection('access');    # create a connection
+$<font color="#663300">conn</font>->PConnect('northwind');   # connect to MS-Access, northwind dsn
+<font color="#000000">$<font color="#663300">shipto</font> = <b>$conn-&gt;qstr</b>(&quot;John's Old Shoppe&quot;);

+<b>if</b> ($<font color="#663300">conn</font>->Execute($sql) <b>=== false</b>) <b>print</b> 'error inserting';</font>
+?&gt;
+</pre>
+<p>In the above example, we have turned on debugging by setting <b>debug = true</b>. 
+ This will display the SQL statement before execution, and also show any error 
+ messages. There is no need to call <font face="Courier New, Courier, mono"><a href="#errormsg">ErrorMsg</a>()</font> 
+ in this case. For displaying the recordset, see the <font face="Courier New, Courier, mono"><a href="#exrs2html">rs2html</a>() 
+ </font>example.</p>
+ <p>Also see the section on <a href=#errorhandling>Custom Error Handlers</a>.</p>
+<h3>Example 5: MySQL and Menus<a name="ex5"></a></h3>
+<p>Connect to MySQL database <i>agora</i>, and generate a &lt;select&gt; menu 
+ from an SQL statement where the &lt;option&gt; captions are in the 1st column, 
+ and the value to send back to the server is in the 2nd column.</p>
+<pre>&lt;?
+<b>include</b>('adodb.inc.php'); # load code common to ADOdb
+$<font color="#663300">conn</font> = &amp;ADONewConnection('mysql');  # create a connection
+$<font color="#663300">conn</font>->PConnect('localhost','userid','','agora');# connect to MySQL, agora db
+<font color="#000000">$<font color="#663300">sql</font> = 'select CustomerName, CustomerID from customers';
+$<font color="#663300">rs</font> = $<font color="#663300">conn</font>->Execute($sql);
+<b>print</b> <b><font color="#336600">$<font color="#663300">rs</font>-&gt;GetMenu('GetCust','Mary Rosli');
+?&gt;</font></b></font></pre>
+<p>Here we define a menu named GetCust, with the menu option 'Mary Rosli' selected. 
+ See <a href="#getmenu"><font face="Courier New, Courier, mono">GetMenu</font></a><font face="Courier New, Courier, mono">()</font>. 
+ We also have functions that return the recordset as an array: <font face="Courier New, Courier, mono"><a href="#getarray">GetArray</a>()</font>, 
+ and as an associative array with the key being the first column: <a href="#getassoc">GetAssoc</a>().</p>
+<p>
+Aslo new to ADOdb 1.50 or later is the global variable $ADODB_FETCH_MODE. This allows you to define
+whether you want associative or numeric indexing for your arrays.<p>
+
+<h3>Example 6: Connecting to 2 Databases At Once<a name="ex6"></a></h3>
+<pre>&lt;?

+
+$conn1-&gt;Execute('insert ...');
+$conn2-&gt;Execute('update ...');
+?&gt;</pre>
+<p>
+
+<h3>Example 7: Generating Update and Insert SQL<a name="ex7"></a></h3>
+ADOdb 1.31 and later supports two new recordset functions: GetUpdateSQL( ) and 
+GetInsertSQL( ). This allow you to perform a "SELECT * FROM table query WHERE...",
+make a copy of the $rs->fields, modify the fields, and then generate the SQL to
+update or insert into the table automatically.
+<p>
+We show how the functions can be used when
+accessing a table with the following fields: (ID, FirstName, LastName, Created).
+<p>
+Before these functions can be called, you need to initialize the recordset by
+performing a select on the table. Idea and code by Jonathan Younger jyounger#unilab.com.

+<h3>Example 8: Implementing Scrolling with Next and Previous<a name="ex8"></a></h3>
+<p>
+Code and idea by Iv&aacute;n Oliva ivan.oliva#amena.com. <p>
+We use the HTTP Get variable $next_page to keep track of what page to go next and
+ store the current page in the session variable $curr_page.
+<p>
+We call the connection object's PageExecute() function to generate the appropriate recordset, 
+then use the recordset's AtFirstPage() and AtLastPage() functions to determine 
+whether to display the next and previous buttons. <p>

+<h2><a name="errorhandling"></a>Using Custom Error Handlers and PEAR_Error</h2>
+Apart from the old $con->debug = true; way of debugging, ADOdb 1.50 onwards provides 
+another way of handling errors using ADOdb's custom error handlers. 
+<p>
+ADOdb provides two custom handlers which you can modify for your needs.
+The first one is in the <b>ADOdb-errorhandler.inc.php</b> file. This makes
+use of the standard PHP functions <a href=http://php.net/error_reporting>error_reporting</a>
+to control what error messages types to display,
+and <a href=http://php.net/trigger_error>trigger_error</a> which invokes the default
+PHP error handler.
+<p>
+Including the above file  will cause <i>trigger_error($errorstring,E_USER_ERROR)</i>
+to be called when<br>
+(a) Connect() or PConnect() fails, or  <br>
+(b) a function that executes SQL statements such as Execute() or SelectLimit() has an error.<br>
+(c) GenID() appears to go into an infinite loop.
+ <p>
+The $errorstring is generated by ADOdb and will contain useful debugging information similar
+to the error.log data generated below. 
+This file ADOdb-errorhandler.inc.php should be included before you create any ADOConnection objects. 
+<p>
+ If you define error_reporting(0), no errors will be shown. 
+ If you set error_reporting(E_ALL), all errors will be displayed on the screen.
+ <pre>
+&lt;?php
+<b>error_reporting(E_ALL); # show any error messages triggered
+include('ADOdb-errorhandler.inc.php');</b>
+include('adodb.inc.php');
+include('tohtml.inc.php');
+$c = NewADOConnection('mysql');
+$c->PConnect('localhost','root','','northwind');
+$rs=$c->Execute('select * from productsz'); #invalid table productsz');
+if ($rs) $rs2html($rs);
+?>
+</pre>
+ <p>
+ If you want to log the error message, you can do so by defining the following optional
+  constants ADODB_ERROR_LOG_TYPE and ADODB_ERROR_LOG_DEST. ADODB_ERROR_LOG_TYPE is 
+  the error log message type (see <a href=http://php.net/error_log>error_log</a>
+  in the PHP manual). In this case we set 
+  it to 3, which means log to the file defined by the constant ADODB_ERROR_LOG_DEST.
+ 
+<pre>
+&lt;?php
+<b>error_reporting(0); # do not echo any errors
+define('ADODB_ERROR_LOG_TYPE',3);
+define('ADODB_ERROR_LOG_DEST','C:/errors.log');
+include('ADOdb-errorhandler.inc.php');</b>
+include('adodb.inc.php');
+include('tohtml.inc.php');
+
+$c = NewADOConnection('mysql');
+$c->PConnect('localhost','root','','northwind');
+$rs=$c->Execute('select * from productsz'); ## invalid table productsz
+if ($rs) $rs2html($rs);
+?>
+</pre>
+The following message will be logged in the error.log file:
+<pre>
+(2001-10-28 14:20:38) mysql error: [1146: Table 'northwind.productsz' doesn't exist] in
+ EXECUTE("select * from productsz")
+</pre>
+The second error handler is <b>ADOdb-errorpear.inc.php</b>. This will create a 
+PEAR_Error derived object whenever an error occurs. The last PEAR_Error object 
+created can be retrieved using ADODB_Pear_Error(). 
+<pre>
+&lt;?php
+<b>include('ADOdb-errorpear.inc.php');</b>
+include('adodb.inc.php');
+include('tohtml.inc.php');
+$c = NewADOConnection('mysql');
+$c->PConnect('localhost','root','','northwind');
+$rs=$c->Execute('select * from productsz'); #invalid table productsz');
+if ($rs) $rs2html($rs);
+else &#123;
+	<b>$e = ADODB_Pear_Error();
+	echo '&lt;p>',$e->message(),'&lt;/p>';</b>
+&#125;
+?>
+</pre>
+<p>
+<b>IMPORTANT NOTE: </b>Some buggy database extensions are known to commit all outstanding 
+tranasactions, so you might want to do an explicit $DB->RollbackTrans() in your 
+user-defined error handler. At the time of writing, Interbase is known to have this problem.
+<p>
+You can use a PEAR_Error derived class by defining the constant ADODB_PEAR_ERROR_CLASS 
+before the ADOdb-errorpear.inc.php file is included. For easy debugging, you can 
+set the default error handler in the beginning of the PHP script to PEAR_ERROR_DIE, 
+which will cause an error message to be printed, then halt script execution: 
+<pre>
+include('PEAR.php');
+PEAR::setErrorHandling('PEAR_ERROR_DIE');
+</pre>
+<p> Note that we do not explicitly return a PEAR_Error object to you when an error 
+  occurs. We return false instead. You have to call ADODB_Pear_Error() to get 
+  the last error or use the PEAR_ERROR_DIE technique. 
+<h2><a name="dsn"></a> Data Source Names</h2>
+<p>We now support connecting using PEAR style DSN's. A DSN is a connection string 
+  of the form:</p>
+<p>$dsn = <i>&quot;$driver://$username:$password@$hostname/$databasename&quot;</i>;</p>
+<p>You pass the DSN to the static class function DB::Connect. An example:</p>
+<pre>   include_once('../adodb/adodb-pear.inc.php');
+   $username = 'root';
+   $password = '';
+   $hostname = 'localhost';
+   $databasename = 'xphplens';
+   $driver = 'mysql';
+   $dsn = &quot;$driver://$username:$password@$hostname/$databasename&quot;;</pre>
+<pre>   $db = DB::Connect($dsn);<br>   $rs = $db-&gt;Execute('select firstname,lastname from adoxyz');
+   $cnt = 0;
+   while ($arr = $rs-&gt;FetchRow()) {
+		print_r($arr); print &quot;&lt;br&gt;&quot;;
+   }</pre>
+<p>This requires PEAR to be installed and in the default include path in php.ini.</p>
+<h2><a name="caching"></a>Caching of Recordsets</h2>
+<p>ADOdb now supports caching of recordsets using the  CacheExecute( ), 
+CachePageExecute( ) and CacheSelectLimit( ) functions. There are similar to the
+non-cache functions, except that they take a new first parameter, $secs2cache.
+<p> An example: 
+<pre>
+<b>include</b>('adodb.inc.php'); # load code common to ADOdb
+$ADODB_CACHE_DIR = '/usr/ADODB_cache';
+$<font color="#663300">conn</font> = &amp;ADONewConnection('mysql');  # create a connection
+$<font color="#663300">conn</font>->PConnect('localhost','userid','','agora');# connect to MySQL, agora db
+<font color="#000000">$<font color="#663300">sql</font> = 'select CustomerName, CustomerID from customers';
+$<font color="#663300">rs</font> = $<font color="#663300">conn</font>->CacheExecute(15,$sql);</font></pre>
+<p><font color="#000000"> The first parameter is the number of seconds to cache 
+  the query. Subsequent calls to that query will used the cached version stored 
+  in $ADODB_CACHE_DIR. To force a query to execute and flush the cache, call CacheExecute() 
+  with the first parameter set to zero. Alternatively, use the CacheFlush($sql) 
+  call. </font></p>
+<p><font color="#000000">For the sake of security, we recommend you set <i>register_globals=off</i> 
+  in php.ini if you are using $ADODB_CACHE_DIR.</font></p>
+<p>In ADOdb 1.80 onwards, the secs2cache parameter is optional in CacheSelectLimit() and
+CacheExecute(). If you leave it out, it will use the $connection->cacheSecs parameter, which defaults
+to 60 minutes.
+<pre>
+	$conn->Connect(...);
+	$conn->cacheSecs = 3600*24; // cache 24 hours
+	$rs = $conn->CacheExecute('select * from table');
+</pre>
+<font color="#000000"> 
+<hr>
+<h1>Class Reference<a name="Ref"></a></h1>
+<p>Function parameters with [ ] around them are optional.</p>
+</font>
+<h2>Global Variables</h2>
+<h3>$ADODB_COUNTRECS</h3>
+<p>If the database driver API does not support counting the number of records 
+  returned in a SELECT statement, the function RecordCount() is emulated when 
+  the global variable $ADODB_COUNTRECS is set to true, which is the default. We 
+  emulate this by buffering the records, which can take up large amounts of memory 
+  for big recordsets. Set this variable to false for the best performance. This 
+  variable is checked every time a query is executed, so you can selectively choose 
+  which recordsets to count.</p>
+<h3><font color="#000000">$ADODB_CACHE_DIR</font></h3>
+<font color="#000000"> 
+<p>If you are using recordset caching, this is the directory to save your recordsets 
+  in. Define this before you call any caching functions such as CacheExecute( 
+  ). We recommend setting <i>register_globals=off</i> in php.ini if you use this 
+  feature for security reasons.</p>
+<p>If you are using Unix and apache, you might need to set your cache directory 
+  permissions to something similar to the following:</p>
+</font> 
+<p>chown -R apache /path/to/adodb/cache<br>
+  chgrp -R apache /path/to/adodb/cache <font color="#000000"> </font></p>
+<font color="#000000">
+<h3><a name="adodb_fetch_mode"></a>$ADODB_FETCH_MODE</h3>
+<p>This is a global variable that determines how arrays are retrieved by recordsets. 
+  The recordset saves this value on creation (eg. in Execute( ) or SelectLimit( 
+  )), and any subsequent changes to $ADODB_FETCH_MODE have no affect on existing 
+  recordsets, only on recordsets created in the future.</p>
+<p>The following constants are defined:</p>
+</font> 
+<p><font color="#000000">define('ADODB_FETCH_DEFAULT',0);<br>
+  define('ADODB_FETCH_NUM',1);<br>
+  define('ADODB_FETCH_ASSOC',2);<br>
+  define('ADODB_FETCH_BOTH',3); </font></p>
+<font color="#000000"> 
+<p> An example: 
+<pre>
+	$ADODB_<b>FETCH_MODE</b> = ADODB_FETCH_NUM;
+	$rs1 = $db->Execute('select * from table');
+	$ADODB_<b>FETCH_MODE</b> = ADODB_FETCH_ASSOC;
+	$rs2 = $db->Execute('select * from table');
+	print_r($rs1->fields); # shows <i>array([0]=>'v0',[1] =>'v1')</i>
+	print_r($rs2->fields); # shows <i>array(['col1']=>'v0',['col2'] =>'v1')</i>
+</pre>
+<p> As you can see in the above example, both recordsets store and use different 
+  fetch modes based on the $ADODB_FETCH_MODE setting when the recordset was created 
+  by Execute().</p>
+<p>If no fetch mode is predefined, the fetch mode defaults to ADODB_FETCH_DEFAULT. 
+  The behaviour of this default mode varies from driver to driver, so do not rely 
+  on ADODB_FETCH_DEFAULT. For portability, we recommend sticking to ADODB_FETCH_NUM 
+  or ADODB_FETCH_ASSOC. Many drivers do not support ADODB_FETCH_BOTH.</p>
+<hr>
+<h2>ADOConnection<a name="ADOConnection"></a></h2>
+<p>Object that performs the connection to the database, executes SQL statements 
+  and has a set of utility functions for standardising the format of SQL statements 
+  for issues such as concatenation and date formats.</p>
+<h3>ADOConnection Fields</h3>
+<p><b>databaseType</b>: Name of the database system we are connecting to. Eg. 
+  <b>odbc</b> or <b>mssql</b> or <b>mysql</b>.</p>
+<p><b>dataProvider</b>: The underlying mechanism used to connect to the database. 
+  Normally set to <b>native</b>, unless using <b>odbc</b> or <b>ado</b>.</p>
+<p><b>host: </b>Name of server or data source name (DSN) to connect to.</p>
+<p><b>database</b>: Name of the database or to connect to. If ado is used, it 
+  will hold the ado data provider.</p>
+<p><b>user</b>: Login id to connect to database. Password is not saved for security 
+  reasons.</p>
+<p><b>raiseErrorFn</b>: Allows you to define an error handling function. See ADOdb-errorhandler.inc.php 
+  for an example.</p>
+<p><b>debug</b>: Set to <i>true</i> to make debug statements to appear.</p>
+<p><b>concat_operator</b>: Set to '+' or '||' normally. The operator used to concatenate 
+  strings in SQL. Used by the <b><a href="#concat">Concat</a></b> function.</p>
+<p><b>fmtDate</b>: The format used by the <b><a href="#dbdate">DBDate</a></b> 
+  function to send dates to the database. is '#Y-m-d#' for Microsoft Access, and 
+  ''Y-m-d'' for MySQL.</p>
+<p><b>fmtTimeStamp: </b>The format used by the <b><a href="#dbtimestamp">DBTimeStamp</a></b> 
+  function to send timestamps to the database. </p>
+<p><b>true</b>: The value used to represent true.Eg. '.T.'. for Foxpro, '1' for 
+  Microsoft SQL.</p>
+<p><b>false: </b> The value used to represent false. Eg. '.F.'. for Foxpro, '0' 
+  for Microsoft SQL.</p>
+<p><b>replaceQuote</b>: The string used to escape quotes. Eg. double single-quotes 
+  for Microsoft SQL, and backslash-quote for MySQL. Used by <a href="#qstr">qstr</a>.</p>
+<p><b>autoCommit</b>: indicates whether automatic commit is enabled. Default is 
+  true.</p>
+<p><b>charSet</b>: set the default charset to use. Currently only interbase supports 
+  this. </p>
+<p><b>metaTablesSQL</b>: SQL statement to return a list of available tables. Eg. 
+  <i>SHOW TABLES</i> in MySQL.</p>
+<p><b>genID</b>: The latest id generated by GenID() if supported by the database.</p>
+<p><b>cacheSecs</b>: The number of seconds to cache recordsets if CacheExecute() 
+  or CacheSelectLimit() do not define the $secs2cache parameter.</p>
+<p><b>sysDate</b>: The database function to call to get the current date and time 
+  using the native date/timestamp type.</p>
+<hr>
+<h3>ADOConnection Main Functions</h3>
+<p><b>ADOConnection( )</b></p>
+<p>Constructor function. Do not call this directly. Use ADONewConnection( ) instead.</p>
+<p><b>Connect<a name="Connect"></a>($host,[$user],[$password],[$database])</b></p>
+<p>Non-persistent connect to data source or server $<b>host</b>, using userid 
+  $<b>user </b>and password $<b>password</b>. If the server supports multiple 
+  databases, connect to database $<b>database</b>. </p>
+<p>Returns true/false depending on connection.</p>
+<p>ADO Note: If you are using a Microsoft ADO and not OLEDB, you can set the $database 
+  parameter to the OLEDB data provider you are using.</p>
+<p>PostgreSQL: An alternative way of connecting to the database is to pass the 
+  standard PostgreSQL connection string in the first parameter $host, and the 
+  other parameters will be ignored.</p>
+<p>For Oracle and Oci8, there are two ways to connect. First is to use the TNS 
+  name defined in your local tnsnames.ora (or ONAMES or HOSTNAMES). Place the name 
+  in the $database field, 
+  and set the $host field to false. Alternatively, set $host to the server, and 
+  $database to the database SID, this bypassed tnsnames.ora. 
+<p>Examples: 
+<pre> # $oraname in tnsnames.ora/ONAMES/HOSTNAMES
+ $conn->Connect(false, 'scott', 'tiger', $oraname); 
+ $conn->Connect('server:1521', 'scott', 'tiger', 'ServiceName'); # bypass tnsnames.ora</pre>
+<p>There are many examples of connecting to a database at <a href="http://php.weblogs.com/adodb">php.weblogs.com/ADOdb</a>, 
+  and in the testdatabases.inc.php file included in the release.</p>
+<p><b>PConnect<a name="PConnect"></a>($host,[$user],[$password],[$database])</b></p>
+<p>Persistent connect to data source or server $<b>host</b>, using userid $<b>user</b> 
+  and password $<b>password</b>. If the server supports multiple databases, connect 
+  to database $<b>database</b>.</p>
+<p>Returns true/false depending on connection. See Connect( ) above for more info.</p>
+<p><b>Execute<a name="Execute"></a>($sql,$inputarr=false)</b></p>
+<p>Execute SQL statement $<b>sql</b> and return derived class of ADORecordSet 
+  if successful. Note that a record set is always returned on success, even if 
+  we are executing an insert or update statement.</p>
+<p>Returns derived class of ADORecordSet. Eg. if connecting via mysql, then ADORecordSet_mysql 
+  would be returned. False is returned if there was an error in executing the 
+  sql.</p>
+<p>The $inputarr parameter can be used for binding variables to parameters. Below 
+  is an Oracle example:</p>
+<pre>
+ $conn->Execute("SELECT * FROM TABLE WHERE COND=:val", array('val'=> $val));
+ </pre>
+<p>Another example, using ODBC,which uses the ? convention:</p>
+<pre>
+  $conn->Execute("SELECT * FROM TABLE WHERE COND=?", array($val));
+</pre>
+<i>Binding variables</i><br>
+Variable binding speeds the compilation and caching of SQL statements, leading 
+to higher performance. Currently Oracle and ODBC support variable binding. ODBC 
+style ? binding is emulated in databases that do not support binding. 
+<p> Variable binding in the odbc and oci8po drivers. 
+<pre>
+$rs = $db->Execute('select * from table where val=?', array('10'));
+</pre>
+Variable binding in the oci8 driver. 
+<pre>
+$rs = $db->Execute('select name from table where val=:key', 
+  array('key' => 10));
+</pre>
+<p><b>CacheExecute<a name="CacheExecute"></a>($secs2cache,$sql,$inputarr=false)</b></p>
+<p>Similar to Execute, except that the recordset is cached for $secs2cache seconds 
+  in the $ADODB_CACHE_DIR directory. If CacheExecute() is called again with the 
+  same parameters, same database, same userid, same password, and the cached recordset 
+  has not expired, the cached recordset is returned. 
+<pre>
+  include('adodb.inc.php'); 
+  include('tohtml.inc.php');
+  $ADODB_<b>CACHE_DIR</b> = '/usr/local/ADOdbcache';
+  $conn = &ADONewConnection('mysql'); 
+  $conn->PConnect('localhost','userid','password','database');
+  $rs = $conn-><b>CacheExecute</b>(15, 'select * from table'); # cache 15 secs
+  rs2html($rs); /* recordset to html table */  
+</pre>
+<p></p>
+<p> Alternatively, since ADOdb 1.80, the $secs2cache parameter is optional:</p>
+<pre>	$conn-&gt;Connect(...);
+   	$conn-&gt;cacheSecs = 3600*24; // cache 24 hours
+	$rs = $conn-&gt;CacheExecute('select * from table');
+</pre>
+<p>If multiple calls to CacheExecute() are made and the recordset is still cached, 
+  the $secs2cache parameter does not prolong the time the recordset is cached 
+  (it is ignored). Use CacheExecute() only with SELECT statements.</p>
+<p>Performance note: I have done some benchmarks and found that they vary so greatly 
+  that it's better to talk about when caching is of benefit. When your database 
+  server is <i>much slower </i>than your Web server or the database is <i>very 
+  overloaded </i>then ADOdb's caching is good because it reduces the load on your 
+  database server. If your database server is lightly loaded or much faster than 
+  your Web server, then caching could actually reduce performance. </p>
+<p><b>SelectLimit<a name="SelectLimit"></a>($sql,$numrows=-1,$offset=-1,$inputarr=false)</b></p>
+<p>Returns a recordset if successful. Returns false otherwise. Performs a select 
+  statement, simulating PostgreSQL's SELECT statement, LIMIT $numrows OFFSET $offset 
+  clause.</p>
+<p>In PostgreSQL, SELECT * FROM TABLE LIMIT 3 will return the first 3 records 
+  only. The equivalent is <code>$connection->SelectLimit('SELECT * FROM TABLE',3)</code>. 
+  This functionality is simulated for databases that do not possess this feature.</p>
+<p>And SELECT * FROM TABLE LIMIT 3 OFFSET 2 will return records 3, 4 and 5 (eg. 
+  after record 2, return 3 rows). The equivalent in ADOdb is <code>$connection->SelectLimit('SELECT 
+  * FROM TABLE',3,2)</code>.</p>
+<p>Note that this is the <i>opposite</i> of MySQL's LIMIT clause. You can also 
+  set <code>$connection->SelectLimit('SELECT * FROM TABLE',-1,10)</code> to get 
+  rows 11 to the last row.</p>
+<p>The last parameter $inputarr is for databases that support variable binding 
+  such as Oracle oci8. This substantially reduces SQL compilation overhead. Below 
+  is an Oracle example:</p>
+<pre>
+ $conn->SelectLimit("SELECT * FROM TABLE WHERE COND=:val", 100,-1,array('val'=> $val));
+ </pre>
+<p>The oci8po driver (oracle portable driver) uses the more standard bind variable 
+  of ?: 
+<pre>
+ $conn->SelectLimit("SELECT * FROM TABLE WHERE COND=?", 100,-1,array('val'=> $val));
+</pre>
+<p> 
+<p>Ron Wilson reports that SelectLimit does not work with UNIONs and suggested 
+  the following solution for mssql: 
+<pre>
+>In addition, I found a way to structure the Select Union so that it will
+> work with the optimization in place.  It works under MS-SQL, don't know
+> about the others...  When updating the help file, you could use this as an
+> example of how to structure the SQL --
+<i>No it doesn't work with MySQL -- John<br></i>> 
+> Change:
+>  Select column1 From table1
+>  Union
+>  Select column2 From table2
+> 
+> To:
+>  Select * From (
+>   Select column1 From table1
+>   Union
+>   Select column2 From table2
+>   )
+>  As dummytable

+> Ron</pre>
+<p><b>CacheSelectLimit<a name="CacheSelectLimit"></a>($secs2cache, $sql, $numrows=-1,$offset=-1,$inputarr=false)</b></p>
+<p>Similar to SelectLimit, except that the recordset returned is cached for $secs2cache 
+  seconds in the $ADODB_CACHE_DIR directory. </p>

+<font color="#000000"> 
+<p><b>CacheFlush<a name="CacheFlush"></a>($sql)</b></p>
+<p>Flush (delete) any cached recordsets for the SQL statement $sql in $ADODB_CACHE_DIR. 
+  If you want to flush all cached recordsets, execute the following PHP code (works 
+  only under Unix): <code>system(&quot;rm -f `find &quot;.ADODB_CACHE_DIR.&quot;

+<p><b>ErrorMsg<a name="ErrorMsg"></a>()</b></p>

+<p><b>GenID<a name="genid"></a>($seqName = 'ADOdbseq',$startID=1)</b></p>
+<p>Generate a sequence number (an integer except for mssql). Works for interbase, 
+  mysql, postgresql, oci8, oci8po, mssql, ODBC based (access,vfp,db2,etc) drivers 
+  currently. Uses $seqName as the name of the sequence. GenID() will automatically

+  name. The table has one column, "id" which should be of type integer, or if 
+  you need something larger - numeric(16). 
+<p> For ODBC and databases that do not support sequences natively (eg mssql, mysql), 
+  we create a table for each sequence. If the sequence has not been defined earlier, 
+  it is created with the starting value set in $startID.</p>
+<p>Note that the mssql driver's GenID() used to generate 16 byte GUID's. We now 
+  return integers since 1.90.</p>
+<p><b>UpdateBlob<a name="updateblob"></a>($table,$column,$val,$where)</b></p>
+Allows you to store a blob (in $val) into $table into $column in a row at $where. 
+<p> Usage: 
+<p> 
+<pre>
+	# for oracle
+	$conn->Execute('INSERT INTO blobtable (id, blobcol) VALUES (1, empty_blob())');
+	$conn->UpdateBlob('blobtable','blobcol',$blobvalue,'id=1');
+	
+	# non oracle databases
+	$conn->Execute('INSERT INTO blobtable (id, blobcol) VALUES (1, null)');
+	$conn->UpdateBlob('blobtable','blobcol',$blobvalue,'id=1');
+</pre>
+<p> Returns true if succesful, false otherwise. Supported by MySQL, PostgreSQL, 
+  Oci8, Oci8po and Interbase drivers. Other drivers might work, depending on the 
+  state of development.</p>
+<p>Note that when an Interbase blob is retrieved using SELECT, it still needs 
+  to be decoded using $connection->DecodeBlob($blob); to derive the original value 
+  in versions of PHP before 4.1.0. 
+<p><b>UpdateClob<a name="updateclob"></a>($table,$column,$val,$where)</b></p>
+Allows you to store a clob (in $val) into $table into $column in a row at $where. 
+Similar to UpdateBlob (see above), but for Character Large OBjects. 
+<p> Usage: 
+<p> 
+<pre>
+	# for oracle
+	$conn->Execute('INSERT INTO clobtable (id, clobcol) VALUES (1, empty_clob())');
+	$conn->UpdateBlob('clobtable','clobcol',$clobvalue,'id=1');
+	
+	# non oracle databases
+	$conn->Execute('INSERT INTO clobtable (id, clobcol) VALUES (1, null)');
+	$conn->UpdateBlob('clobtable','clobcol',$clobvalue,'id=1');
+</pre>
+<p><b>UpdateBlobFile<a name="updateblobfile"></a>($table,$column,$path,$where,$blobtype='BLOB')</b></p>
+<p>Similar to UpdateBlob, except that we pass in a file path to where the blob 
+  resides. 
+<p>returns true if successful, false otherwise. 
+<p><b>GetUpdateSQL<a name="getupdatesql"></a>(&$rs, $arrFields, $forceUpdate=false,$magicq=false)</b></p>
+<p>Generate SQL to update a table given a recordset $rs, and the modified fields 
+  of the array $arrFields (which must be an associative array holding the column 
+  names and the new values) are compared with the current recordset. If $forceUpdate 
+  is true, then we also generate the SQL even if $arrFields is identical to $rs-&gt;fields.	
+  Requires the recordset to be associative. $magicq is used to indicate whether 
+  magic quotes are enabled (see qstr()).</p>
+<p><b>GetInsertSQL<a name="getinsertsql"></a>(&$rs, $arrFields,$magicq=false)</b></p>
+<p>Generate SQL to insert into a table given a recordset $rs. Requires the query 
+  to be associative. $magicq is used to indicate whether magic quotes are enabled 
+  (for qstr()).</p>
+<b>PageExecute<a name="pageexecute"></a>($sql, $nrows, $page, $inputarr=false)</b> 
+<p>Used for pagination of recordset. $page is 1-based. See <a href="#ex8">Example

+<p><b>Close<a name="Close"></a>( )</b></p>
+<p>Close the database connection. PHP4 proudly states that we no longer have to 
+  clean up at the end of the connection because the reference counting mechanism 
+  of PHP4 will automatically clean up for us.</p>
+<p><b>BeginTrans<a name="Begintrans"></a>( )</b></p>
+<p>Begin a transaction. Turns off autoCommit. Returns true if successful. Some 
+  databases will always return false if transaction support is not available. 
+  Interbase, Oracle and MSSQL support transactions. Any open transactions will 
+  be rolled back when the connection is closed.</p>
+<p>
+The following is the wrong way to use transactions:
+<pre>
+$DB->BeginTrans();
+$DB->Execute("update table1 set val=$val1 where id=$id");
+$DB->Execute("update table2 set val=$val2 where id=$id");
+$DB->CommitTrans();
+</pre>
+<p>because you perform no error checking. It is possible to update table1 and for
+the update on table2 to fail. Here is a better way:
+<pre>
+$DB->BeginTrans();
+$ok = $DB->Execute("update table1 set val=$val1 where id=$id");
+if ($ok) $ok = $DB->Execute("update table2 set val=$val2 where id=$id");
+if ($ok) $DB->CommitTrans();
+else $DB->RollbackTrans();
+</pre>
+<p>Another way is (since ADOdb 2.0):
+<pre>
+$DB->BeginTrans();
+$ok = $DB->Execute("update table1 set val=$val1 where id=$id");
+if ($ok) $ok = $DB->Execute("update table2 set val=$val2 where id=$id");
+$DB->CommitTrans($ok);
+</pre>
+<p>You can also use the ADOdb <a href=#errorhandling>error handler</a> to die and 
+rollback your transactions for you transparently. Some buggy database extensions are known
+to commit all outstanding tranasactions, so you might want to explicitly do a 
+$DB->RollbackTrans() in your error handler for safety.
+<p><b>CommitTrans<a name="CommitTrans"></a>($ok=true)</b></p>
+<p>End a transaction successfully. Returns true if successful. If the database 
+  does not support transactions, will return true also as data is always committed. 
+</p>
+<p>If you pass the parameter $ok=false, the data is rolled back. See example in BeginTrans().</p>
+<p><b>RollbackTrans<a name="RollbackTrans"></a>( )</b></p>
+<p>End a transaction, rollback all changes. Returns true if successful. If the 
+  database does not support transactions, will return false as data is never rollbacked. 
+</p>
+<p><b>GetOne<a name="getone"></a>($sql)</b></p>
+<p>Executes the SQL and returns the first field of the first row. The recordset 
+  and remaining rows are discarded for you automatically. If an error occur, false 
+  is returned.</p>
+<p><b>GetRow<a name="getrow"></a>($sql)</b></p>
+<p>Executes the SQL and returns the first row as an array. The recordset and remaining

+<p>Adds a bind parameter in a fashion that is compatible with Microsoft SQL Server 
+  and Oracle oci8. The parameters are:<br>
+  <br>
+  $<i><b>stmt</b></i> Statement returned by Prepare() or PrepareSP().<br>
+  $<i><b>var</b></i> PHP variable to bind to.<br>
+  $<i><b>name</b></i> Name of stored procedure variable name to bind to.<br>
+  [$<i><b>isOutput</b></i>] Indicates direction of parameter 0/false=IN 1=OUT 
+  2= IN/OUT. This is ignored in oci8 as this driver auto-detects the direction.<br>
+  [$<b>maxLen</b>] Maximum length of the parameter variable.<br>

+  docs at php.net for more info on legal values for type.</p>
+<p>In mssql, $opt can hold the following elements: array('type' =&gt; integer,

+$db-&gt;Parameter($stmt,$ret,'RETVAL',true);<br>$db-&gt;Execute($stmt);
+</pre>
+<p>Note that the only difference between the oci8 and mssql implementations is 
+  the syntax of $sql.</p>
+If $type parameter is set to false, in mssql, $type will be dynamicly determined 
+based on the type of the PHP variable passed <font face="Courier New, Courier, mono">(string 
+=&gt; SQLCHAR, boolean =&gt;SQLINT1, integer =&gt;SQLINT4 or float/double=&gt;SQLFLT8)</font>. 
+In oci8, $type can be set to OCI_B_FILE (Binary-File), OCI_B_CFILE (Character-File), 
+OCI_B_CLOB (Character-LOB), OCI_B_BLOB (Binary-LOB) and OCI_B_ROWID (ROWID). To

+<pre>$id = 0; $i = 0;
+$stmt = $db-&gt;PrepareSP( <font color="#993300">&quot;update table set val=:i where id=:id&quot;</font>);
+$db-&gt;Parameter($stmt,$id,'id');

+	$db-&gt;Execute($stmt); <br>}</pre>
+<p><b>Bind<a name="Bind"></a>($stmt, $var, $size=4001, $type=false, $name=false)</b></p>
+</font> 
+<p><font color="#000000">This is a low-level function supported only by the oci8 
+  driver. <b>Avoid using</b> unless you only want to support Oracle. The Parameter(

+<p><font color="#000000">Bind( ) allows you to use bind variables in your sql

+  The first invocation of Bind() will match :0, the second invocation will match 
+  :1, etc. Binding can provide 100% speedups for insert, select and update statements. 
+  </font></p>
+<p>The other variables, $size sets the buffer size for data storage, $type is the optional
+descriptor type OCI_B_FILE (Binary-File), OCI_B_CFILE (Character-File), OCI_B_CLOB (Character-LOB), OCI_B_BLOB (Binary-LOB) and OCI_B_ROWID (ROWID). 
+Lastly, instead of using the default :0, :1, etc names, you can define your own bind-name using
+$name.
+<p><font color="#000000">The following example shows 3 bind variables being used: 
+  p1, p2 and p3. These variables are bound to :0, :1 and :2.</font></p>

+<p>Returns the concatenated string.</p>
+<p><b>DBDate<a name="DBDate"></a>($date)</b></p>
+<p>Format the $<b>date</b> in the format the database accepts; this can be a Unix

+<p>Returns the date as a quoted string.</p>
+<p><b>DBTimeStamp<a name="DBTimeStamp"></a>($ts)</b></p>
+<p>Format the timestamp $<b>ts</b> in the format the database accepts; this can 
+  be a Unix integer timestamp or an ISO format Y-m-d H:i:s. Uses the fmtTimeStamp 
+  field, which holds the format to use. If null or false or '' is passed in, it

+<p>Quotes a string to be sent to the database. The $<b>magic_quotes_enabled</b> 
+  parameter may look funny, but the idea is if you are quoting a string extracted 
+  from a POST/GET variable, then pass get_magic_quotes_gpc() as the second parameter. 
+  This will ensure that the variable is not quoted twice, once by <i>qstr</i> 
+  and once by the <i>magic_quotes_gpc</i>.</p>
+<p>Eg.<font face="Courier New, Courier, mono"> $s = $db-&gt;qstr(HTTP_GET_VARS['name'],get_magic_quotes_gpc());</font></p>

+<p>Not supported by interbase/firebird currently. </p>
+<p><b>Insert_ID<a name="Inserted_ID"></a>( )</b></p>
+<p>Returns the last autonumbering ID inserted. Returns false if function not supported. 
+</p>
+<p>Only supported by databases that support auto-increment or object id's, such 
+  as PostgreSQL, MySQL and MSSQL currently. PostgreSQL returns the OID, which 
+  can change on a database reload. This function might only give accurate results

+<h2>ADORecordSet<a name="ADORecordSet"></a></h2>
+<p>When an SQL statement successfully is executed by <font face="Courier New, Courier, mono">ADOConnection-&gt;Execute($sql),</font>an 
+  ADORecordSet object is returned. This object contains a virtual cursor so we 
+  can move from row to row, functions to obtain information about the columns 
+  and column types, and helper functions to deal with formating the results to 
+  show to the user.</p>
+<h3>ADORecordSet Fields</h3>
+<p><b>fields: </b>Array containing the current row. This is not associative, but 
+  is an indexed array from 0 to columns-1. See also the function <b><a href="#fields">Fields</a></b>, 
+  which behaves like an associative array.</p>
+<p><b>dataProvider</b>: The underlying mechanism used to connect to the database. 
+  Normally set to <b>native</b>, unless using <b>odbc</b> or <b>ado</b>.</p>
+<p><b>blobSize</b>: Maximum size of a char, string or varchar object before it 
+  is treated as a Blob (Blob's should be shown with textarea's). See the <a href="#metatype">MetaType</a> 
+  function.</p>
+<p><b>sql</b>: Holds the sql statement used to generate this record set.</p>
+<p><b>canSeek</b>: Set to true if Move( ) function works.</p>
+<p><b>EOF</b>: True if we have scrolled the cursor past the last record.</p>
+<h3>ADORecordSet Functions</h3>
+<p><b>ADORecordSet( )</b></p>
+<p>Constructer. Normally you never call this function yourself.</p>
+<p><b>GetAssoc<a name="GetAssoc"></a>([$force_array])</b></p>
+<p>Generates an associative array from the recordset if the number of columns 
+  is greater than 2. The array is generated from the current cursor position till 
+  EOF. The first column of the recordset becomes the key to the rest of the array. 
+  If the columns is equal to two, then the key directly maps to the value unless 
+  $force_array is set to true, when an array is created for each key. Inspired 
+  by PEAR's getAssoc.</p>
+<p>Example:</p>
+<p>We have the following data in a recordset:</p>
+<p>row1: Apple, Fruit, Edible<br>
+  row2: Cactus, Plant, Inedible<br>
+  row3: Rose, Flower, Edible</p>
+<p>GetAssociation will generate the following associative array:</p>
+<p>Apple =&gt; [Fruit, Edible]<br>
+  Cactus =&gt; [Plant, Inedible]<br>
+  Rose =&gt; [Flower,Edible]</p>
+<p>Returns:</p>
+<p>The associative array, or false if an error occurs.</p>
+<p><b>GetArray<a name="GetArray"></a>([$number_of_rows])</b></p>
+<p>Generate an array of records from the current cursor position, indexed from 
+  0 to $number_of_rows - 1. If $number_of_rows is undefined, till EOF.</p>
+<p><b>GetRows<a name="GetRows"></a>([$number_of_rows])</b></p>
+Generate an array of records from the current cursor position. Synonym for GetArray() 
+for compatibility with Microsoft ADO. 
+<p> <b>GetMenu<a name="GetMenu"></a>($name, [$default_str=''], [$blank1stItem=true], 
+  [$multiple_select=false], [$size=0], [$moreAttr=''])</b></p>
+<p>Generate a HTML menu (&lt;select&gt;&lt;option&gt;&lt;option&gt;&lt;/select&gt;). 
+  The first column of the recordset (fields[0]) will hold the string to display 
+  in the option tags. If the recordset has more than 1 column, the second column 
+  (fields[1]) is the value to send back to the web server.. The menu will be given 
+  the name $<i>name</i>. 
+<p> If $<i>default_str</i> is defined, then if $<i>default_str</i> == fields[0], 
+  that field is selected. If $<i>blank1stItem</i> is true, the first option is 
+  empty. $<i>Default_str</i> can be array for a multiple select listbox.</p>
+<p>To get a listbox, set the $<i>size</i> to a non-zero value (or pass $default_str 
+  as an array). If $<i>multiple_select</i> is true then a listbox will be generated 
+  with $<i>size</i> items (or if $size==0, then 5 items) visible, and we will 
+  return an array to a server. Lastly use $<i>moreAttr </i> to add additional 
+  attributes such as javascript or styles. </p>
+<p>Menu Example 1: <code>GetMenu('menu1','A',true)</code> will generate a menu: 
+  <select name='menu1'>
+    <option> 
+    <option value=1 selected>A 
+    <option value=2>B 
+    <option value=3>C 
+  </select>
+  for the data (A,1), (B,2), (C,3). Also see <a href="#ex5">example 5</a>.</p>
+<p>Menu Example 2: For the same data, <code>GetMenu('menu1',array('A','B'),false)</code> 
+  will generate a menu with both A and B selected: <br>
+  <select name='menu1' multiple size=3>
+    <option value=1 selected>A 
+    <option value=2 selected>B 
+    <option value=3>C 
+  </select>
+<p> <b>GetMenu2<a name="GetMenu2"></a>($name, [$default_str=''], [$blank1stItem=true], 
+  [$multiple_select=false], [$size=0], [$moreAttr=''])</b></p>
+<p>This is nearly identical to GetMenu, except that the $<i>default_str</i> is 
+  matched to fields[1] (the option values).</p>
+<p>Menu Example 3: Given the data in menu example 2, <code>GetMenu2('menu1',array('1','2'),false)</code> 
+  will generate a menu with both A and B selected in menu example 2, but this 
+  time the selection is based on the 2nd column, which holds the values to return 
+  to the Web server. 
+<p><b>UserDate<a name="UserDate"></a>($str, [$fmt])</b></p>

+  to parse $<b>str</b>, and $<b>fmt</b> defaults to Y-m-d if not defined.</p>
+<p><b>UserTimeStamp<a name="UserTimeStamp"></a>($str, [$fmt])</b></p>
+<p>Converts the timestamp string $<b>str</b> to another format. The timestamp

+  to parse $<b>str</b>, and $<b>fmt</b> defaults to Y-m-d H:i:s if not defined. 
+</p>
+<p><b>UnixDate<a name="unixdate"></a>($str)</b></p>
+<p>Parses the date string $<b>str</b> and returns it in unix mktime format (eg. 
+  a number indicating the seconds after January 1st, 1970). Expects the date to 
+  be in Y-m-d H:i:s format, except for Sybase and Microsoft SQL Server, where 
+  M d Y is also accepted (the 3 letter month strings are controlled by a global 
+  array, which might need localisation).</p>
+<p>This function is available in both ADORecordSet and ADOConnection since 1.91.</p>
+<p><b>UnixTimeStamp<a name="unixtimestamp"></a>($str)</b></p>
+<p>Parses the timestamp string $<b>str</b> and returns it in unix mktime format 
+  (eg. a number indicating the seconds after January 1st, 1970). Expects the date 
+  to be in Y-m-d H:i:s format, except for Sybase and Microsoft SQL Server, where 
+  M d Y h:i:sA is also accepted (the 3 letter month strings are controlled by 
+  a global array, which might need localisation).</p>
+This function is available in both ADORecordSet and ADOConnection since 1.91. 
+<p><b>MoveNext<a name="MoveNext"></a>( )</b></p>
+<p>Move the internal cursor to the next row. The <b>fields</b> array is automatically 
+  updated. Return false if unable to do so, otherwise true.</p>
+<p>Example:</p>
+<pre>$rs = $db-&gt;Execute($sql);
+if ($rs) 
+	while (!$rs-&gt;EOF) {
+ 		ProcessArray($rs->fields);	
+		$rs->MoveNext();
+	} </pre>
+<p><b>Move<a name="Move"></a>($to)</b></p>
+<p>Moves the internal cursor to a specific row $<b>to</b>. Rows are zero-based 
+  eg. 0 is the first row. The <b>fields</b> array is automatically updated. For 
+  databases that do not support scrolling internally, ADOdb will simulate forward 
+  scrolling. Some databases do not support backward scrolling. If the $<b>to</b> 
+  position is after the EOF, $<b>to</b> will move to the end of the RecordSet 
+  for most databases. Some obscure databases using odbc might not behave this 
+  way.</p>
+<p>Note: This function uses <i>absolute positioning</i>, unlike Microsoft's ADO.</p>
+<p>Returns true or false. If false, the internal cursor is not moved in most implementations, 
+  so AbsolutePosition( ) will return the last cursor position before the Move( 
+  ). </p>
+<p><b>MoveFirst<a name="MoveFirst"></a>()</b></p>
+<p>Internally calls Move(0). Note that some databases do not support this function.</p>
+<p><b>MoveLast<a name="MoveLast"></a>()</b></p>
+<p>Internally calls Move(RecordCount()-1). Note that some databases do not support 
+  this function.</p>
+<p><b>GetRowAssoc</b><a name="getrowassoc"></a>($toUpper=true)</p>
+<p>The above function is no longer the prefered way of getting associative arrays. 
+  Use the <a href=#adodb_fetch_mode>$ADODB_FETCH_MODE</a> variable instead. </p>
+<p>Returns an associative array containing the current row. The keys to the array 
+  are the column names. The column names are upper-cased for easy access. To get 
+  the next row, you will still need to call MoveNext(). </p>
+<p>For example:<br>
+  Array ( [ID] => 1 [FIRSTNAME] => Caroline [LASTNAME] => Miranda [CREATED] => 
+  2001-07-05 ) </p>
+<p>Note: do not use GetRowAssoc() with $ADODB_FETCH_MODE = ADODB_FETCH_ASSOC. 
+  Because they have the same functionality, they will interfere with each other.</p>
+</font> 
+<p><font color="#000000"><b>AbsolutePage<a name="absolutepage"></a>($page=-1) </b></font></p>
+<p>Returns the current page. Requires PageExecute()/CachePageExecute() to be called. See <a href=#ex8>Example 8</a>.</p>
+<font color="#000000"> 
+<p><b>AtFirstPage<a name="AtFirstPage">($status='')</a></b></p>
+<p>Returns true if at first page (1-based). Requires PageExecute()/CachePageExecute() 
+  to be called. See <a href=#ex8>Example 8</a>.</p>
+<p><b>AtLastPage<a name="AtLastPage">($status='')</a></b></p>
+<p>Returns true if at last page (1-based). Requires PageExecute()/CachePageExecute() 
+  to be called. See <a href=#ex8>Example 8</a>.</p>
+<p><b>Fields</b><a name="fields"></a>(<b>$colname</b>)</p>
+<p>This function is deprecated. Use <a href="#adodb_fetch_mode">$ADODB_FETCH_MODE</a> 
+  instead. </p>
+<p>Some database extensions (eg. MySQL) return arrays that are both associative 
+  and indexed if you use the native extensions. GetRowAssoc() does not return 
+  arrays that combine associative and indexed elements. Returns the value of the 
+  associated column $<b>colname</b> for the current row. The column name is case-insensitive.</p>
+<p><b>FetchRow</b><a name="fetchrow"></a>()</p>
+</font>
+<p><font color="#000000">Returns array containing current row, or false if EOF. 
+  FetchRow( ) internally moves to the next record after returning the current 
+  row. </font></p>
+<p><font color="#000000">Warning: Do not mix using FetchRow() with MoveNext().</font></p>

+<p><b>FetchField<a name="FetchField"></a>($column_number)</b></p>
+<p>Returns an object containing the <b>name</b>, <b>type</b> and <b>max_length</b> 
+  of the associated field. If the max_length cannot be determined reliably, it 
+  will be set to -1. The column numbers are zero-based. See <a href="#ex2">example 
+  2.</a></p>
+<p><b>FieldCount<a name="FieldCount"></a>( )</b></p>
+<p>Returns the number of fields (columns) in the record set.</p>
+<p><b>RecordCount<a name="RecordCount"></a>( )</b></p>
+<p>Returns the number of rows in the record set. If the number of records returned 
+  cannot be determined from the database driver API, we will buffer all rows and 
+  return a count of the rows after all the records have been retrieved. This buffering 
+  can be disabled (for performance reasons) by setting the global variable $ADODB_COUNTRECS 
+  = false. When disabled, RecordCount( ) will return -1 for certain databases. 
+  See the supported databases list above for more details. </p>
+<p> RowCount is a synonym for RecordCount.</p>
+<p><b>PO_RecordCount<a name="po_recordcount"></a>($table, $where)</b></p>
+<p>Returns the number of rows in the record set. If the database does not support 
+  this, it will perform a SELECT COUNT(*) on the table $table, with the given 
+  $where condition to return an estimate of the recordset size.</p>
+<p>$numrows = $rs-&gt;PO_RecordCount(&quot;articles_table&quot;, &quot;group=$group&quot;);</p>
+<p><b>FetchObject<a name="FetchObject"></a>($toupper=true)</b></p>
+<p>Returns the current row as an object. If you set $toupper to true, then the 
+  object fields are set to upper-case. Note: The newer FetchNextObject() is the 
+  recommended way of accessing rows as objects. See below.</p>
+<p><b>FetchNextObject<a name="FetchNextObject"></a>($toupper=true)</b></p>
+<p>Gets the current row as an object and moves to the next row automatically. 
+  Returns false if at end-of-file. If you set $toupper to true, then the object 
+  fields are set to upper-case.</p>
+<pre>
+$rs = $db->Execute('select firstname,lastname from table');
+if ($rs) &#123;
+	while ($o = $rs->FetchNextObject()) &#123;
+		print "$o->FIRSTNAME, $o->LASTNAME&lt;BR>";
+	&#125;
+&#125;
+</pre>
+<p>There is some trade-off in speed in using FetchNextObject(). If performance 
+  is important, you should access rows with the <code>fields[]</code> array. 
+<p> 
+<p><b>CurrentRow<a name="CurrentRow"></a>( )</b></p>
+<p>Returns the current row of the record set. 0 is the first row.</p>
+<p><b>AbsolutePosition<a name="abspos"></a>( )</b></p>
+<p>Synonym for <b>CurrentRow</b> for compatibility with ADO. Returns the current 
+  row of the record set. 0 is the first row.</p>
+<p><b>MetaType<a name="MetaType"></a>($nativeDBType[,$field_max_length],[$fieldobj])</b></p>
+<p>Determine what <i>generic</i> meta type a database field type is given its 
+  native type $<b>nativeDBType</b> and the length of the field $<b>field_max_length</b>. 
+  Note that field_max_length can be -1 if it is not known. The field object returned

+<h3>function rs2html<a name="rs2html"></a>($adorecordset,[$tableheader_attributes],

+<p>This is a standalone function (rs2html = recordset to html) that is similar 
+  to PHP's <i>odbc_result_all</i> function, it prints a ADORecordSet, $<b>adorecordset</b> 
+  as a HTML table. $<b>tableheader_attributes</b> allow you to control the table 
+  <i>cellpadding</i>, <i>cellspacing</i> and <i>border</i> attributes. Lastly 
+  you can replace the database column names with your own column titles with the

+<h3>Differences Between this ADOdb library and Microsoft ADO<a name="adodiff"></a></h3>
+<ol>
+  <li>ADOdb only supports recordsets created by a connection object. Recordsets 
+    cannot be created independently.</li>
+  <li>ADO properties are implemented as functions in ADOdb. This makes it easier 
+    to implement any enhanced ADO functionality in the future.</li>
+  <li>ADOdb's <font face="Courier New, Courier, mono">ADORecordSet-&gt;Move()</font> 
+    uses absolute positioning, not relative. Bookmarks are not supported.</li>
+  <li><font face="Courier New, Courier, mono">ADORecordSet-&gt;AbsolutePosition() 
+    </font>cannot be used to move the record cursor.</li>
+  <li>ADO Parameter objects are not supported. Instead we have the ADOConnection::<a href="#parameter">Parameter</a>( 
+	) function, which provides a simpler interface for calling preparing parameters 
+	and calling stored procedures.</li>
+  <li>Recordset properties for paging records are available, but implemented as 
+    in <a href=#ex8>Example 8</a>.</li>

+<h1>Database Driver Guide<a name="DriverGuide"></a></h1>
+<p>This describes how to create a class to connect to a new database. To ensure 
+  there is no duplication of work, kindly email me at jlim#natsoft.com.my if you 
+  decide to create such a class.</p>
+<p>First decide on a name in lower case to call the database type. Let's say we 
+  call it xbase. </p>
+<p>Then we need to create two classes ADOConnection_xbase and ADORecordSet_xbase 
+  in the file ADOdb-xbase.inc.php.</p>
+<p>The simplest form of database driver is an adaptation of an existing ODBC driver. 
+  Then we just need to create the class <i>ADOConnection_xbase extends ADOConnection_odbc</i> 
+  to support the new <b>date</b> and <b>timestamp</b> formats, the <b>concatenation</b> 
+  operator used, <b>true</b> and <b>false</b>. For the<i> ADORecordSet_xbase extends 
+  ADORecordSet_odbc </i>we need to change the <b>MetaType</b> function. See<b> 
+  ADOdb-vfp.inc.php</b> as an example.</p>
+<p>More complicated is a totally new database driver that connects to a new PHP 
+  extension. Then you will need to implement several functions. Fortunately, you 
+  do not have to modify most of the complex code. You only need to override a 
+  few stub functions. See <b>ADOdb-mysql.inc.php</b> for example.</p>
+<p>The default date format of ADOdb internally is YYYY-MM-DD (Ansi-92). All dates 
+  should be converted to that format when passing to an ADOdb date function. See 
+  Oracle for an example how we use ALTER SESSION to change the default date format 
+  in _pconnect _connect.</p>
+<p><b>ADOConnection Functions to Override</b></p>
+<p>Defining a constructor for your ADOConnection derived function is optional. 
+  There is no need to call the base class constructor.</p>
+<p>_<b>connect</b>: Low level implementation of Connect. Returns true or false. 
+  Should set the _<b>connectionID</b>.</p>
+<p>_<b>pconnect:</b> Low level implemention of PConnect. Returns true or false. 
+  Should set the _<b>connectionID</b>.</p>
+<p>_<b>query</b>: Execute a query. Returns the queryID, or false.</p>
+<p>_<b>close: </b>Close the connection -- PHP should clean up all recordsets. 
+</p>
+<p><b>ErrorMsg</b>: Stores the error message in the private variable _errorMsg. 
+</p>
+<p>The ADOConnection functions BeginTrans( ), CommitTrans( ), RollbackTrans( ) 
+  are reserved for future expansion.</p>
+<p><b>ADOConnection Fields to Set</b></p>
+<p>_<b>bindInputArray</b>: Set to true if binding of parameters for SQL inserts 
+  and updates is allowed using ?, eg. as with ODBC.</p>
+<p><b>fmtDate</b></p>
+<p><b>fmtTimeStamp</b></p>
+<p><b>true</b></p>
+<p><b>false</b></p>
+<p><b>concat_operator</b></p>
+<p><b>replaceQuote</b></p>
+<p><b>hasLimit</b> support SELECT * FROM TABLE LIMIT 10 of MySQL.</p>
+<p><b>hasTop</b> support Microsoft style SELECT TOP 10 * FROM TABLE.</p>
+<p><b>ADORecordSet Functions to Override</b></p>
+<p>You will need to define a constructor for your ADORecordSet derived class that 
+  calls the parent class constructor.</p>
+<p><b>FetchField: </b> as documented above in ADORecordSet</p>
+<p>_<b>initrs</b>: low level initialization of the recordset: setup the _<b>numOfRows</b> 
+  and _<b>numOfFields</b> fields -- called by the constructor.</p>
+<p>_<b>seek</b>: seek to a particular row. Do not load the data into the fields 
+  array. This is done by _fetch. Returns true or false. Note that some implementations 
+  such as Interbase do not support seek. Set canSeek to false.</p>
+<p>_<b>fetch</b>: fetch a row using the database extension function and then move 
+  to the next row. Sets the <b>fields</b> array. If the parameter $ignore_fields 
+  is true then there is no need to populate the <b>fields</b> array, just move 
+  to the next row. then Returns true or false.</p>
+<p>_<b>close</b>: close the recordset</p>
+<p><b>Fields</b>: If the array row returned by the PHP extension is not an associative 
+  one, you will have to override this. See ADOdb-odbc.inc.php for an example. 
+  For databases such as MySQL and MSSQL where an associative array is returned, 
+  there is no need to override this function.</p>
+<p><b>ADOConnection Fields to Set</b></p>
+<p>canSeek: Set to true if the _seek function works.</p>

+<h2>Change Log<a name="Changes"></a><a name=ChangeLog></a></h2>
+<p><b>2.00 13 May 2002</b></p>
+<p>Added drivers <i>informix72</i> for pre-7.3 versions, and <i>oci805</i> for 
+  oracle 8.0.5, and postgres64 for postgresql 6.4 and earlier. The postgres and postgres7 drivers
+  are now identical.
+<p>Interbase now partially supports ADODB_FETCH_BOTH, by defaulting to ASSOC mode.
+<p>Proper support for blobs in mssql. Also revised blob support code 
+is base class. Now UpdateBlobFile() calls UpdateBlob() for consistency.
+<p>Added support for changed odbc_fetch_into api in php 4.2.0 
+with $conn-&gt;_has_stupid_odbc_fetch_api_change.
+<p>Fixed spelling of tablock locking hint in GenID( ) for mssql. 
+<p>Added RowLock( ) to several databases, including oci8, informix, sybase, etc. 
+  Fixed where error in mssql RowLock().
+<p>Added sysDate and sysTimeStamp properties to most database drivers. These are the sql
+functions/constants for that database that return the current date and current timestamp, and 
+are useful for portable inserts and updates.
+<p>Support for RecordCount() caused date handling in sybase and mssql to break. 
+Fixed, thanks to Toni Tunkkari, by creating derived classes for ADORecordSet_array for
+both databases. Generalized using arrayClass property. Also to support RecordCount(), 
+changed metatype handling for ado drivers. Now the type returned in FetchField 
+  is no longer a number, but the 1-char data type returned by MetaType.
+  At the same time, fixed a lot of date handling. Now mssql support dmy and mdy date formats. 
+Also speedups in sybase and mssql with preg_match and ^ in date/timestamp handling.
+Added support in sybase and mssql for 24 hour clock in timestamps (no AM/PM).
+<p>Extensive revisions to informix driver - thanks to Samuel CARRIERE samuel_carriere#hotmail.com 
+<p>Added $ok parameter to CommitTrans($ok) for easy rollbacks.
+<p>Fixed odbc MetaColumns and MetaTables to save and restore $ADODB_FETCH_MODE.
+<p>Some odbc drivers did not call the base connection class constructor. Fixed.
+<p>Fixed regex for GetUpdateSQL() and GetInsertSQL() to support more legal character combinations.
+
+<p><b>1.99 21 April 2002</b></p>
+<p>Added emulated RecordCount() to all database drivers if $ADODB_COUNTRECS = true 
+  (which it is by default). Inspired by Cristiano Duarte (cunha17#uol.com.br). 
+<p>Unified stored procedure support for mssql and oci8. Parameter() and PrepareSP() 
+  functions implemented. 
+<p>Added support for SELECT FIRST in informix, modified hasTop property to support 
+  this. 
+<p>Changed csv driver to handle updates/deletes/inserts properly (when Execute() returns true).
+Bind params also work now, and raiseErrorFn with csv driver. Added csv driver to QA process. 
+<p>Better error checking in oci8 UpdateBlob() and UpdateBlobFile().
+<p>Added TIME type to MySQL - patch by Manfred h9125297#zechine.wu-wien.ac.at
+<p>Prepare/Execute implemented for Interbase/Firebird 
+<p>Changed some regular expressions to be anchored by /^ $/ for speed.
+<p>Added UnixTimeStamp() and UnixDate() to ADOConnection(). Now these functions 
+  are in both ADOConnection and ADORecordSet classes.
+<p>Empty recordsets were not cached - fixed.
+<p>Thanks to Gaetano Giunta (g.giunta#libero.it) for the oci8 code review. We 
+  didn't agree on everything, but i hoped we agreed to disagree! 
+<p><b>1.90 6 April 2002</b></p>
+<p>Now all database drivers support fetch modes ADODB_FETCH_NUM and ADODB_FETCH_ASSOC, though
+	still not fully tested. Eg. Frontbase, Sybase, Informix.
+<p>NextRecordSet() support for mssql. Contributed by "Sven Axelsson" sven.axelsson#bokochwebb.se
+<p>Added blob support for SQL Anywhere. Contributed by Wade Johnson wade#wadejohnson.de
+<p>Fixed some security loopholes in server.php. Server.php also supports fetch mode.
+<p>Generalized GenID() to support odbc and mssql drivers. Mssql no longer generates GUID's.
+<p>Experimental RowLock($table,$where) for mssql.
+<p>Properly implemented Prepare() in oci8 and ODBC.
+<p>Added Bind() support to oci8 to support Prepare().
+<p>Improved error handler. Catches CacheExecute() and GenID() errors now.
+<p>Now if you are running php from the command line, debugging messages do not output html formating.
+Not 100% complete, but getting there.
+<p><b>1.81 22 March 2002</b></p>
+<p>Restored default $ADODB_FETCH_MODE = ADODB_FETCH_DEFAULT for backward compatibility.
+<p>SelectLimit for oci8 improved - Our FIRST_ROWS optimization now does not overwrite existing hint.
+<p>New Sybase SQL Anywhere driver. Contributed by Wade Johnson wade#wadejohnson.de
+<p><b>1.80 15 March 2002</b></p>
+<p>Redesigned directory structure of ADOdb files. Added new driver directory where
+all database drivers reside.
+<p>Changed caching algorithm to create subdirectories. Now we scale better.
+<p>Informix driver now supports insert_id(). Contribution by "Andrea Pinnisi" pinnisi#sysnet.it
+<p>Added experimental ISO date and FetchField support for informix.
+<p>Fixed a quoting bug in Execute() with bind parameters, causing problems with blobs.
+<p>Mssql driver speedup by 10-15%.
+<p>Now in CacheExecute($secs2cache,$sql,...), $secs2cache is optional. If missing, it will
+take the value defined in $connection->cacheSecs (default is 3600 seconds). Note that
+CacheSelectLimit(), the secs2cache is still compulsory - sigh.
+<p>Sybase SQL Anywhere driver (using ODBC) contributed by Wade Johnson wade#wadejohnson.de
+<p><b>1.72 8 March 2002</b></p>
+<p>Added @ when returning Fields() to prevent spurious error - "Michael William Miller" mille562#pilot.msu.edu
+<p>MetaDatabases() for postgres contributed by Phil pamelant#nerim.net
+ <p>Mitchell T. Young (mitch#youngfamily.org) contributed informix driver.
+ <p>Fixed rs2html() problem. I cannot reproduce, so probably a problem with pre PHP 4.1.0 versions,
+  when supporting new ADODB_FETCH_MODEs.
+ <p>Mattia Rossi (mattia#technologist.com) contributed BlobDecode() and UpdateBlobFile() for postgresql
+ using the postgres specific pg_lo_import()/pg_lo_open() - i don't use them but hopefully others will
+ find this useful. See <a href="http://phplens.com/lens/lensforum/msgs.php?id=1262">this posting</a>
+ for an example of usage.
+ <p>Added UpdateBlobFile() for uploading files to a database.
+ <p>Made UpdateBlob() compatible with oci8po driver.
+ <p>Added noNullStrings support to oci8 driver. Oracle changes all ' ' strings to nulls,
+  so you need to set strings to ' ' to prevent the nullifying of strings. $conn->noNullStrings = true;
+  will do this for you automatically. This is useful when you define a char column as NOT NULL.
+  <p>Fixed UnixTimeStamp() bug - wasn't setting minutes and seconds properly. Patch from Agusti Fita i Borrell agusti#anglatecnic.com.
+  <p>Toni Tunkkari added patch for sybase dates. Problem with spaces in day part of date fixed.
+ <p><b>1.71 18 Jan 2002</b></p>
+ <p>Sequence start id support. Now $conn->Gen_ID('seqname', 50) to start sequence from 50.
+ <p>CSV driver fix for selectlimit, from Andreas - akaiser#vocote.de.
+<P>Gam3r spotted that a global variable was undefined in the session handler. 
+<p>Mssql date regex had error. Fixed - reported by Minh Hoang vb_user#yahoo.com.
+<p>DBTimeStamp() and DBDate() now accept iso dates and unix timestamps. This means
+that the PostgreSQL handling of dates in GetInsertSQL() and GetUpdateSQL() can
+be removed. Also if these functions are passed '' or null or false, we return a SQL null.
+<p>GetInsertSQL() and GetUpdateSQL() now accept a new parameter, $magicq to 
+indicate whether quotes should be inserted based on magic quote settings - suggested by
+dj#4ict.com.
+<p>Reformated docs slightly based on suggestions by Chris Small.
+ <p><b>1.65 28 Dec 2001</b></p>
+ <p>Fixed borland_ibase class naming bug.
+ <p>Now instead of using $rs->fields[0] internally, we use reset($rs->fields) so 
+ that we are compatible with ADODB_FETCH_ASSOC mode. Reported by Nico S.
+ <p>Changed recordset constructor and _initrs() for oci8 so that it returns the field definitions even
+ if no rows in the recordset. Reported by Rick Hickerson (rhickers#mv.mv.com).
+ <p>Improved support for postgresql in GetInsertSQL and GetUpdateSQL by
+  "mike" mike#partner2partner.com  and "Ryan Bailey" rebel#windriders.com
+ <p><b>1.64 20 Dec 2001</b></p>
+<p>Danny Milosavljevic &lt;danny.milo#gmx.net> added some patches for MySQL error handling
+and displaying default values.
+<p>Fixed some ADODB_FETCH_BOTH inconsistencies in odbc and interbase.
+<p>Added more tests to test suite to cover ADODB_FETCH_* and ADODB_ERROR_HANDLER.
+<p>Added firebird (ibase) driver
+<p>Added borland_ibase driver for interbase 6.5
+<p><b>1.63 13 Dec 2001</b></p>
+Absolute to the ADOdb-lib.inc.php file not set properly. Fixed.<p>
+
+<p><b>1.62 11 Dec 2001</b></p>
+<p>Major speedup of ADOdb for low-end web sites by reducing the php code loading and compiling
+cycle. We conditionally compile not so common functions. 
+Moved csv code to ADOdb-csvlib.inc.php to reduce adodb.inc.php parsing. This file
+is loaded only when the csv/proxy driver is used, or CacheExecute() is run.
+Also moved PageExecute(), GetSelectSQL() and GetUpdateSQL() core code to ADOdb-lib.inc.php.
+This reduced the 70K main adodb.inc.php file to 55K, and since at least 20K of the file
+is comments, we have reduced 50K of code in adodb.inc.php to 35K. There
+ should be 35% reduction in memory and thus 35% speedup in compiling the php code for the
+main adodb.inc.php file.
+<p>Highly tuned SelectLimit() for oci8 for massive speed improvements on large files. 
+Selecting 20 rows starting from the 20,000th row of a table is now 7 times faster. 
+Thx to Tomas V V Cox.
+<p>Allow . and # in table definitions in GetInsertSQL and GetUpdateSQL.
+ See ADODB_TABLE_REGEX constant. Thx to Ari Kuorikoski.
+<p>Added ADODB_PREFETCH_ROWS constant, defaulting to 10. This determines the number
+of records to prefetch in a SELECT statement. Only used by oci8.</p>
+<p>Added high portability Oracle class called oci8po. This uses ? for bind variables, and 
+lower cases column names.</p>
+<p>Now all database drivers support $ADODB_FETCH_MODE, including interbase, ado, and odbc:
+ADODB_FETCH_NUM and ADODB_FETCH_ASSOC. ADODB_FETCH_BOTH is not fully implemented for all 
+database drivers.
+<p><b>1.61 Nov 2001</b></p>
+<p>Added PO_RecordCount() and PO_Insert_ID(). PO stands for portable. Pablo Roca 
+  [pabloroca#mvps.org]</p>
+<p>GenID now returns 0 if not available. Safer is that you should check $conn->hasGenID 
+  for availability.</p>
+<p>M'soft ADO we now correctly close recordset in _close() peterd#telephonetics.co.uk</p>
+<p>MSSQL now supports GenID(). It generates a 16-byte GUID from mssql newid() 
+  function.</p>
+<p>Changed ereg_replace to preg_replace in SelectLimit. This is a fix for mssql. 
+  Ereg doesn't support t or n! Reported by marino Carlos xaplo#postnuke-espanol.org</p>
+<p>Added $recordset->connection. This is the ADOConnection object for the recordset. 
+Works with cached and normal recordsets. Surprisingly, this had no affect on performance!</p>
+<p><b>1.54 15 Nov 2001</b></p>
+Fixed some more bugs in PageExecute().  I am getting sick of bug in this and will have to 
+reconsider my QA here. The main issue is that I don't use PageExecute() and 
+to check whether it is working requires a visual inspection of the html generated currently.
+It is possible to write a test script but it would be quite complicated :(
+<p> More speedups of SelectLimit() for DB2, Oci8, access, vfp, mssql.
+<p>
+
+<p><b>1.53 7 Nov 2001</b></p>
+Added support for ADODB_FETCH_ASSOC for ado and odbc drivers.<p>
+Tuned GetRowAssoc(false) in postgresql and mysql.<p>
+Stephen Van Dyke contributed ADOdb icon, accepted with some minor mods.<p>
+Enabled Affected_Rows() for postgresql<p>
+Speedup for Concat() using implode() - Benjamin Curtis ben_curtis#yahoo.com<p>
+Fixed some more bugs in PageExecute() to prevent infinite loops<p>
+<p><b>1.52 5 Nov 2001</b></p>
+Spelling error in CacheExecute() caused it to fail. $ql should be $sql in line 625!<p>
+Added fixes for parsing [ and ] in GetUpdateSQL().
+<p><b>1.51 5 Nov 2001</b></p>
+<p>Oci8 SelectLimit() speedup by using OCIFetch().
+<p>Oci8 was mistakenly reporting errors when $db->debug = true.
+<p>If a connection failed with ODBC, it was not correctly reported - fixed.
+<p>_connectionID was inited to -1, changed to false.
+<p>Added $rs->FetchRow(), to simplify API, ala PEAR DB
+<p>Added PEAR DB compat mode, which is still faster than PEAR! See ADOdb-pear.inc.php.
+<p>Removed postgres pconnect debugging statement.
+<p><b>1.50 31 Oct 2001</b></p>
+<p>ADOdbConnection renamed to ADOConnection, and ADOdbFieldObject to ADOFieldObject.
+<p>PageExecute() now checks for empty $rs correctly, and the errors in the docs on this subject have been fixed.
+<p>odbc_error() does not return 6 digit error correctly at times. Implemented workaround.
+<p>Added ADORecordSet_empty class. This will speedup INSERTS/DELETES/UPDATES because the return
+object created is much smaller.
+<p>Added Prepare() to odbc, and oci8 (but doesn't work properly for oci8 still).
+<p>Made pgsql a synonym for postgre7, and changed SELECT LIMIT to use OFFSET for compat with 
+postgres 7.2.
+<p>Revised ADOdb-cryptsession.php thanks to Ari.
+<p>Set resources to false on _close, to force freeing of resources.
+<p>Added ADOdb-errorhandler.inc.php, ADOdb-errorpear.inc.php and raiseErrorFn on Freek's urging.
+<p>GetRowAssoc($toUpper=true): $toUpper added as default.
+<p>Errors when connecting to a database were not captured formerly. Now we do it correctly.
+<p><b>1.40 19 September 2001</b></p>
+<p>PageExecute() to implement page scrolling added. Code and idea by Iv&aacute;n Oliva.</p>
+<p>Some minor postgresql fixes.</p>
+<p>Added sequence support using GenID() for postgresql, oci8, mysql, interbase.</p>
+<p>Added UpdateBlob support for interbase (untested).</p>
+<p>Added encrypted sessions (see ADOdb-cryptsession.php). By Ari Kuorikoski &lt;kuoriari#finebyte.com></p>
+<p><b>1.31 21 August 2001</b></p>
+<p>Many bug fixes thanks to "GaM3R (Cameron)" &lt;gamr#outworld.cx>. Some session changes due to Gam3r.
+<p>Fixed qstr() to quote  also.
+<p>rs2html() now pretty printed.
+<p>Jonathan Younger jyounger#unilab.com contributed the great idea GetUpdateSQL() and GetInsertSQL() which
+generates SQL to update and insert into a table from a recordset. Modify the recordset fields
+array, then can this function to generate the SQL (the SQL is not executed).
+<p>"Nicola Fankhauser" &lt;nicola.fankhauser#couniq.com> found some bugs in date handling for mssql.</p>
+<p>Added minimal Oracle support for LOBs. Still under development.</p>
+Added $ADODB_FETCH_MODE so you can control whether recordsets return arrays which are
+numeric, associative or both. This is a global variable you set. Currently only MySQL, Oci8, Postgres
+drivers support this.
+<p>PostgreSQL properly closes recordsets now. Reported by several people.
+<p>
+Added UpdateBlob() for Oracle. A hack to make it easier to save blobs.
+<p>
+Oracle timestamps did not display properly. Fixed.
+<p><b>1.20 6 June 2001</b></p>
+<p>Now Oracle can connect using tnsnames.ora or server and service name</p>
+<p>Extensive Oci8 speed optimizations. 
+Oci8 code revised to support variable binding, and /*+ FIRST_ROWS */ hint.</p>
+<p>Worked around some 4.0.6 bugs in odbc_fetch_into().</p>
+<p>Paolo S. Asioli paolo.asioli#libero.it suggested GetRowAssoc().</p>
+<p>Escape quotes for oracle wrongly set to '. Now '' is used.</p>

+<p>Jumped to version 1.20 because I don't like 13 :-)</p>
+<p><b>1.12 6 June 2001</b></p>

+simplifying the startup code.</p>
+<p>FetchNextObject() added. Suggested by Jakub Marecek. This makes FetchObject() obsolete, as

+>> ADODB Library for PHP4
+
+(c) 2000-2002 John Lim (jlim@natsoft.com.my)
+
+Released under both BSD and GNU Lesser GPL library license. 
+This means you can use it in proprietary products.
+ 
+ 
+>> Introduction
+
+PHP's database access functions are not standardised. This creates a 
+need for a database class library to hide the differences between the 
+different databases (encapsulate the differences) so we can easily 
+switch databases.
+
+We currently support MySQL, Interbase, Sybase, PostgreSQL, Oracle, 
+Microsoft SQL server,  Foxpro ODBC, Access ODBC, Informix, DB2 ODBC,
+Sybase SQL Anywhere, generic ODBC and Microsoft's ADO. 
+
+We hope more people will contribute drivers to support other databases.
+
+
+>> Documentation and Examples
+
+Refer to readme.htm for full documentation and examples. There is also a 
+tutorial tute.htm that contrasts ADODB code with mysql code.
+
+
+>>> Files
+Adodb.inc.php is the main file. You need to include only this file.
+
+Adodb-*.inc.php are the database specific driver code.
+
+Test.php contains a list of test commands to exercise the class library.
+
+Adodb-session.php is the PHP4 session handling code.
+
+Testdatabases.inc.php contains the list of databases to apply the tests on.
+
+Benchmark.php is a simple benchmark to test the throughput of a simple SELECT 
+statement for databases described in testdatabases.inc.php. The benchmark
+tables are created in test.php.
+
+readme.htm is the main documentation.
+
+tute.htm is the tutorial.

+ <div align=right><img src="cute_icons_for_site/adodb.gif"></div></td></tr></table>
+ 
+ If you are writing an application that is used in multiple environments and 
+  operating systems, you need to plan to support multiple databases. This article 
+  is based on my experiences with multiple database systems, stretching from 4th 
+  Dimension in my Mac days, to the databases I currently use, which are: Oracle, 
+  FoxPro, Access, MS SQL Server and MySQL. Although most of the advice here applies 
+  to using SQL with Perl, Python and other programming languages, I will focus on PHP and how 
+  the <a href="http://php.weblogs.com/adodb">ADOdb</a> database abstraction library 
+  offers some solutions.<p></p>
+<p>Most database vendors practice product lock-in. The best or fastest way to 
+  do things is often implemented using proprietary extensions to SQL. This makes 
+  it extremely hard to write portable SQL code that performs well under all conditions. 
+  When the first ANSI committee got together in 1984 to standardize SQL, the database 
+  vendors had such different implementations that they could only agree on the 
+  core functionality of SQL. Many important application specific requirements 
+  were not standardized, and after so many years since the ANSI effort began, 
+  it looks as if much useful database functionality will never be standardized. 
+  Even though ANSI-92 SQL has codified much more, we still have to implement portability 
+  at the application level.</p>

+<p>The SELECT statement has been standardized to a great degree. Nearly every 
+  database supports the following:</p>
+<p>SELECT [cols] FROM [tables]<br>
+  &nbsp;&nbsp;[WHERE conditions]<br>
+  &nbsp; [GROUP BY cols]<br>
+  &nbsp; [HAVING conditions] <br>
+  &nbsp; [ORDER BY cols]</p>
+<p>But so many useful techniques can only be implemented by using proprietary 
+  extensions. For example, when writing SQL to retrieve the first 10 rows for 
+  paging, you could write...</p>
+<table width="80%" border="1" cellspacing="0" cellpadding="0" align="center">
+  <tr> 
+    <td><b>Database</b></td>
+    <td><b>SQL Syntax</b></td>
+  </tr>
+  <tr> 
+    <td>DB2</td>
+    <td>select * from table fetch first 10 rows only</td>
+  </tr>
+  <tr> 
+    <td>Informix</td>
+    <td>select first 10 * from table</td>
+  </tr>
+  <tr> 
+    <td>Microsoft SQL Server and Access</td>
+    <td>select top 10 * from table</td>
+  </tr>
+  <tr> 
+    <td>MySQL and PostgreSQL</td>
+    <td>select * from table limit 10</td>
+  </tr>
+  <tr> 
+    <td>Oracle</td>
+    <td>select * from (select * from table) where rownum &lt;= 10</td>
+  </tr>
+</table>
+<p>This feature of getting a subset of data is so useful that in the PHP class 
+  library ADOdb, we have a SelectLimit( ) function that allows you to hide the 
+  implementation details within a function that will rewrite your SQL for you:</p>
+<pre>$connection-&gt;SelectLimit('select * from table', 10);
+</pre>
+<p><b>Selects: Fetch Modes</b></p>
+<p>PHP allows you to retrieve database records as arrays. You can choose to have 
+  the arrays indexed by field name or number. However different low-level PHP 
+  database drivers are inconsistent in their indexing efforts. ADOdb allows you 
+  to determine your prefered mode. You set this by setting the variable $ADODB_FETCH_MODE 
+  to either of the constants ADODB_FETCH_NUM (for numeric indexes) or ADODB_FETCH_ASSOC 
+  (using field names as an associative index).</p>
+<p>The default behaviour of ADOdb varies depending on the database you are using. 
+  For consistency, set the fetch mode to either ADODB_FETCH_NUM (for speed) or 
+  ADODB_FETCH_ASSOC (for convenience) at the beginning of your code. </p>
+<p><b>Selects: Counting Records</b></p>
+<p>Another problem with SELECTs is that some databases do not return the number 
+  of rows retrieved from a select statement. This is because the highest performance 
+  databases will return records to you even before the last record has been found. 
+</p>
+<p>In ADOdb, RecordCount( ) returns the number of rows returned, or will emulate 
+  it by buffering the rows and returning the count after all rows have been returned. 
+  This can be disabled for performance reasons when retrieving large recordsets 
+  by setting the global variable $ADODB_COUNTRECS = false. This variable is checked 
+  every time a query is executed, so you can selectively choose which recordsets 
+  to count.</p>
+<p>If you prefer to set $ADODB_COUNTRECS = false, ADOdb still has the PO_RecordCount( 
+  ) function. This will return the number of rows, or if it is not found, it will 
+  return an estimate using SELECT COUNT(*):</p>
+<pre>$rs = $db-&gt;Execute(&quot;select * from table where state=$state&quot;);
+$numrows = $rs-&gt;PO_RecordCount('table', &quot;state=$state&quot;);</pre>
+<p><b>Selects: Locking</b> </p>
+<p>SELECT statements are commonly used to implement row-level locking of tables. 
+  Other databases such as Oracle, Interbase, PostgreSQL and MySQL with InnoDB 
+  do not require row-level locking because they use versioning to display data 
+  consistent with a specific point in time.</p>
+<p>Currently, I recommend encapsulating the row-level locking in a separate function, 
+  such as RowLock($table, $where):</p>
+<pre>$connection-&gt;BeginTrans( );
+$connection-&gt;RowLock($table, $where); </pre>
+<pre><font color=green># some operation</font></pre>
+<pre>if ($ok) $connection-&gt;CommitTrans( );
+else $connection-&gt;RollbackTrans( );
+</pre>
+<p><b>Selects: Outer Joins</b></p>
+<p>Not all databases support outer joins. Furthermore the syntax for outer joins 
+  differs dramatically between database vendors. One portable (and possibly slower) 
+  method of implementing outer joins is using UNION.</p>
+<p>In Microsoft SQL Server a left outer join between two tables t1 and t2 could 
+  look like:</p>
+<pre>SELECT t1.col1, t1.col2, t2.cola <br>  FROM t1 LEFT JOIN t2 ON t1.col = t2.col</pre>
+<p>This can be emulated using:</p>
+<pre>SELECT t1.col1, t1.col2, t2.cola FROM t1, t2 <br>       WHERE t1.col = t2.col 
+   UNION ALL
+SELECT col1, col2, null FROM t1 <br>       WHERE t1.col not in (select distinct col from t2)</pre>
+<h3><b>Inserts</b> </h3>
+<p>When you create records, you need to generate unique id's for each record. 
+  There are two common techniques: (1) auto-incrementing columns and (2) sequences. 
+</p>
+<p>Auto-incrementing columns are supported by MySQL, Sybase and Microsoft Access 
+  and SQL Server. However most other databases do not support this feature. So 
+  for portability, you have little choice but to use sequences. Sequences are 
+  special functions that return a unique incrementing number every time you call 
+  it, suitable to be used as database keys. In ADOdb, we use the GenID( ) function. 
+  It has takes a parameter, the sequence name. Different tables can have different 
+  sequences. </p>
+<pre>$id = $connection-&gt;GenID('sequence_name');<br>$connection-&gt;Execute(&quot;insert into table (id, firstname, lastname) <br>               values ($id, $firstname, $lastname)&quot;);</pre>
+<p>For databases that do not support sequences natively, ADOdb emulates sequences 
+  by creating a table for every sequence.</p>
+<h3><b>Binding</b></h3>
+<p>Binding variables in an SQL statement is another tricky feature. Binding is 
+  useful because it allows pre-compilation of SQL. When inserting multiple records 
+  into a database in a loop, binding can offer a 50% (or greater) speedup. However 
+  many databases such as Access and MySQL do not support binding natively and 
+  there is some overhead in emulating binding. Furthermore, different databases 
+  (specificly Oracle!) implement binding differently. My recommendation is to 
+  use binding if your database queries are too slow, but make sure you are using 
+  a database that supports it like Oracle. </p>
+<p>ADOdb supports portable Prepare/Execute with:</p>
+<pre>$stmt = $db-&gt;Prepare('select * from customers where custid=? and state=?');
+$rs = $db-&gt;Execute($stmt, array($id,'New York'));</pre>
+<h2>DDL</h2>
+<p>There are database design tools such as ERWin or Dezign that allow you to generate 
+  data definition language commands such as ALTER TABLE or CREATE INDEX from Entity-Relationship 
+  diagrams. Other developers such as Manuel Lemos have developed portable XML 
+  based schemas for PHP with Metabase. I think this might suit many developers, 
+  but I prefer to manually define the database tables. This is because the placement 
+  of tables and selection of the different types of indexes has to be planned 
+  based on the number of hard disks and the i/o characteristics of the data. This 
+  can only be done manually. Here are some tuning hints:</p>
+<ul>
+  <li>The most important and frequently used tables deserve to be placed on their 
+    own separate hard disks. </li>
+  <li>Indexes and data should be kept on different hard disks. </li>
+  <li>Transaction logs and rollback segments deserve their own hard disks.</li>
+  <li>Be prepared to waste space. You probably need at least 5 hard disks for 
+    a high-performance database system:<br>
+    - 1 hard disk for the operating system and temporary data, <br>
+    - 1 for data,<br>
+    - 1 for indexes, <br>
+    - 1 for rollback, <br>
+    - 1 for transaction logs.</li>
+</ul>
+<h3>Data Types</h3>
+<p>Stick to a few data types that are available in most databases. Char, varchar 
+  and numeric/number are supported by most databases. Most other data types (including 
+  integer, boolean and float) cannot be relied on being available. I recommend 
+  using char(1) or number(1) to hold booleans. </p>
+<p>Different databases have different ways of representing dates and timestamps/datetime. 
+  ADOdb attempts to display all dates in ISO (YYYY-MM-DD) format. ADOdb also provides 
+  DBDate( ) and DBTimeStamp( ) to convert dates to formats that are acceptable 
+  to that database. Both functions accept Unix integer timestamps and date strings 
+  in ISO format.</p>
+<pre>$date1 = $connection-&gt;DBDate(time( ));<br>$date2 = $connection-&gt;DBTimeStamp('2002-02-23 13:03:33');</pre>
+<p>We also provide functions to convert database dates to Unix timestamps:</p>
+<pre>$unixts = $recordset-&gt;UnixDate('#2002-02-30#'); <font color="green"># MS Access date =&gt; unix timestamp</font></pre>
+<p>The maximum length of a char/varchar field is also database specific. You can 
+  only assume that field lengths of up to 250 characters are supported. This is 
+  normally impractical for web based forum or content management systems. You 
+  will need to be familiar with how databases handle large objects (LOBs). ADOdb 
+  implements two functions, UpdateBlob( ) and UpdateClob( ) that allow you to 
+  update fields holding Binary Large Objects (eg. pictures) and Character Large 
+  Objects (eg. HTML articles):</p>
+<pre><font color=green># for oracle </font>
+$conn->Execute('INSERT INTO blobtable (id, blobcol) VALUES (1,empty_blob())'); 
+$conn->UpdateBlob('blobtable','blobcol',$blobvalue,'id=1'); 
+   
+<font color=green># non-oracle databases</font>
+$conn->Execute('INSERT INTO blobtable (id, blobcol) VALUES (1, null)'); 
+$conn->UpdateBlob('blobtable','blobcol',$blobvalue,'id=1');
+</pre>
+<p>Null handling is another area where differences can occur. In general, I avoid 
+  using nulls except for dates and default all my numeric and character fields 
+  to 0 or the empty string. This maintains consistency with PHP, where empty strings 
+  and zero are treated as equivalent. However if your database has significant 
+  amounts of missing or unknown data, using nulls might be a good idea.
+<h3><b>Stored Procedures</b></h3>
+<p>Stored procedures are another problem area. Some databases allow recordsets 
+  to be returned in a stored procedure (Microsoft SQL Server and Sybase), and 
+  others only allow output parameters to be returned. Stored procedures sometimes 
+  need to be wrapped in special syntax. For example, Oracle requires such code 
+  to be wrapped in an anonymous block with BEGIN and END. Also internal sql functions 
+  such as +, ||, TRIM( ), SUBSTR( ) or INSTR( ) vary between vendors. </p>
+<p>An example of how to call a stored procedure with 2 parameters and 1 return 
+  value follows:</p>
+<pre>	switch ($db->databaseType) {
+	case '<font color="#993300">mssql</font>':
+	  $sql = <font color="#000000"><font color="#993333">'<font color="#993300">SP_RUNSOMETHING</font>'</font></font>; break;
+	case '<font color="#993300">oci8</font>':
+	  $sql = 
+<font color="#993300">	  </font><font color="#000000"><font color="#993300">&quot;declare RETVAL integer;begin :RETVAL := </font><font color="#000000"><font color="#993333"><font color="#993300">SP_RUNSOMETHING</font></font></font><font color="#993300">(:myid,:group);end;&quot;;
+</font>	  break;</font>
+	default:
+	  die('<font color="#993300">Unsupported feature</font>');
+	}
+<font color="#000000"><font color="green">	# @RETVAL = SP_RUNSOMETHING @myid,@group</font>
+	$stmt = $db-&gt;PrepareSP($sql);    <br>	$db-&gt;Parameter($stmt,$id,'<font color="#993300">myid</font>'); 
+	$db-&gt;Parameter($stmt,$group,'<font color="#993300">group</font>');
+	<font color="green"># true indicates output parameter<br>	</font>$db-&gt;Parameter($stmt,$ret,'<font color="#993300">RETVAL</font>',true); 
+	$db-&gt;Execute($stmt); </font></pre>
+<p>As you can see, the ADOdb API is the same for both databases. But the stored 
+  procedure SQL syntax is quite different between databases and is not portable, 
+  so be forewarned! However sometimes you have little choice as some systems only 
+  allow data to be accessed via stored procedures. This is when the ultimate portability 
+  solution might be the only solution: <i>treating portable SQL as a localization 
+  exercise...</i></p>
+<h3><b>SQL as a Localization Exercise</b></h3>
+<p> In general to provide real portability, you will have to treat SQL coding 
+  as a localization exercise. In PHP, it has become common to define separate 
+  language files for English, Russian, Korean, etc. Similarly, I would suggest 
+  you have separate Sybase, Intebase, MySQL, etc files, and conditionally include 
+  the SQL based on the database. For example, each MySQL SQL statement would be 
+  stored in a separate variable, in a file called 'mysql-lang.inc.php'.</p>
+<pre>$sqlGetPassword = '<font color="#993300">select password from users where userid=%s</font>';
+$sqlSearchKeyword = &quot;<font color="#993300">SELECT * FROM articles WHERE match (title,body) against (%s</font>)&quot;;</pre>
+<p>In our main PHP file:</p>
+<pre><font color=green># define which database to load...</font>
+<b>$database = '<font color="#993300">mysql</font>';
+include_once(&quot;<font color="#993300">$database-lang.inc.php</font>&quot;);</b>
+
+$db = NewADOConnection($database);
+$db->PConnect(...) or die('<font color="#993300">Failed to connect to database</font>');
+
+<font color=green># search for a keyword $word</font>
+$rs = $db-&gt;Execute(sprintf($sqlSearchKeyWord,$db-&gt;qstr($word)));</pre>
+<p>Note that we quote the $word variable using the qstr( ) function. This is because 
+  each database quotes strings using different conventions.</p>
+<p>
+<h3>Final Thoughts</h3>
+<p>The best way to ensure that you have portable SQL is to have your data tables designed using 
+sound principles. Learn the theory of normalization and entity-relationship diagrams and model 
+your data carefully. Understand how joins and indexes work and how they are used to tune performance.

+<h1>Tutorial: Moving from MySQL to ADODB</h1>
+
+<pre>        You say eether and I say eyether, 
+        You say neether and I say nyther; 
+        Eether, eyether, neether, nyther - 
+        Let's call the whole thing off ! 
+<br>
+        You like potato and I like po-tah-to, 
+        You like tomato and I like to-mah-to; 
+        Potato, po-tah-to, tomato, to-mah-to - 
+        Let's call the whole thing off ! 
+</pre>
+<p>I love this song, especially the version with Louis Armstrong and Ella singing 
+  duet. It is all about how hard it is for two people in love to be compatible 
+  with each other. It's about compromise and finding a common ground, and that's 
+  what this article is all about. 
+<p>PHP is all about creating dynamic web-sites with the least fuss and the most 
+  fun. To create these websites we need to use databases to retrieve login information, 
+  to splash dynamic news onto the web page and store forum postings. So let's 
+  say we were using the popular MySQL database for this. Your company has done 
+  such a fantastic job that the Web site is more popular than your wildest dreams. 
+  You find that MySQL cannot scale to handle the workload; time to switch databases. 
+<p> Unfortunately in PHP every database is accessed slightly differently. To connect 
+  to MySQL, you would use <i>mysql_connect()</i>; when you decide to upgrade to 
+  Oracle or Microsoft SQL Server, you would use <i>ocilogon() </i>or <i>mssql_connect()</i> 
+  respectively. What is worse is that the parameters you use for the different 
+  connect functions are different also.. One database says po-tato, the other 
+  database says pota-to. Oh-oh. 
+<h3>Let's NOT call the whole thing off</h3>
+<p>A database wrapper library such as ADODB comes in handy when you need to ensure portability. It provides 
+  you with a common API to communicate with any supported database so you don't have to call things off. <p>
+
+<p>ADODB stands for Active Data Objects DataBase (sorry computer guys are sometimes 
+  not very original). ADODB currently supports MySQL, PostgreSQL, Oracle, Interbase, 
+  Microsoft SQL Server, Access, FoxPro, Sybase, ODBC and ADO. You can download 
+  ADODB from <a href=http://php.weblogs.com/adodb><a href="http://php.weblogs.com/adodb">http://php.weblogs.com/adodb</a></a>.
+<h3>MySQL Example</h3>
+<p>The most common database used with PHP is MySQL, so I guess you should be familiar 
+  with the following code. It connects to a MySQL server at <i>localhost</i>, 
+  database <i>mydb</i>, and executes an SQL select statement. The results are 
+  printed, one line per row. 
+<pre><font color="#666600">$db = <b>mysql_connect</b>(&quot;localhost&quot;, &quot;root&quot;, &quot;password&quot;);
+<b>mysql_select_db</b>(&quot;mydb&quot;,$db);</font>
+<font color="#660000">$result = <b>mysql_query</b>(&quot;SELECT * FROM employees&quot;,$db)</font><code><font color="#663300">;
+if ($result === false) die(&quot;failed&quot;);</font></code> 
+<font color="#006666"><b>while</b> ($fields =<b> mysql_fetch_row</b>($result)) &#123;
+ <b>for</b> ($i=0, $max=sizeof($fields); $i &lt; $max; $i++) &#123;
+        <b>print</b> $fields[$i].' ';
+ &#125;
+ <b>print</b> &quot;&lt;br&gt;\n&quot;;
+&#125;</font> 
+</pre>
+<p>The above code has been color-coded by section. The first section is the connection 
+  phase. The second is the execution of the SQL, and the last section is displaying 
+  the fields. The <i>while</i> loop scans the rows of the result, while the <i>for</i> 
+  loop scans the fields in one row.</p>
+<p>Here is the equivalent code in ADODB</p>

+ &#125;</font> </pre>
+<p></p>
+<p>Now porting to Oracle is as simple as changing the second line to <code>NewADOConnection('oracle')</code>. 
+  Let's walk through the code...</p>
+<h3>Connecting to the Database</h3>
+<p></p>
+<pre><b><font color="#666600">include(&quot;adodb.inc.php&quot;);</b>
+$db = <b>NewADOConnection</b>('mysql');
+$db-&gt;<b>Connect</b>(&quot;localhost&quot;, &quot;root&quot;, &quot;password&quot;, &quot;mydb&quot;);</font></pre>
+<p>The connection code is a bit more sophisticated than MySQL's because our needs 
+  are more sophisticated. In ADODB, we use an object-oriented approach to managing 
+  the complexity of handling multiple databases. We have different classes to 
+  handle different databases. If you aren't familiar with object-oriented programing, 
+  don't worry -- the complexity is all hidden away in the<code> NewADOConnection()</code> 
+  function.</p>
+<p>To conserve memory, we only load the PHP code specific to the database you 
+  are connecting to. We do this by calling <code>NewADOConnection(databasedriver)</code>. 
+  Legal database drivers include <i>mysql, mssql, oracle, oci8, postgres, sybase, 
+  vfp, access, ibase </i>and many others.</p>
+<p>Then we create a new instance of the connection class by calling <code>NewADOConnection()</code>. 
+  Finally we connect to the database using <code>$db-&gt;Connect(). </code></p>
+<h3>Executing the SQL</h3>
+<p><code><font color="#663300">$result = $db-&gt;<b>Execute</b>(&quot;SELECT * 
+  FROM employees&quot;);<br>
+  if ($result === false) die(&quot;failed&quot;)</font></code><code><font color="#663300">;</font></code> 
+  <br>
+</p>
+<p>Sending the SQL statement to the server is straight forward. Execute() will 
+  return a recordset object on successful execution. You should check $result 
+  as we do above.
+<p>An issue that confuses beginners is the fact that we have two types of objects 
+  in ADODB, the connection object and the recordset object. When do we use each?
+<p>The connection object ($db) is responsible for connecting to the database, 
+  formatting your SQL and querying the database server. The recordset object ($result) 
+  is responsible for retrieving the results and formatting the reply as text or 
+  as an array.
+<p>The only thing I need to add is that ADODB provides several helper functions 
+  for making INSERT and UPDATE statements easier, which we will cover in the Advanced 
+  section. 
+<h3>Retrieving the Data<br>
+</h3>
+<pre><font color="#006666"><b>while</b> (!$result-&gt;EOF) &#123;
+   <b>for</b> ($i=0, $max=$result-&gt;<b>FieldCount</b>(); $i &lt; $max; $i++)
+       <b>print</b> $result-&gt;fields[$i].' ';
+   $result-&gt;<b>MoveNext</b>();
+   <b>print</b> &quot;&lt;br&gt;\n&quot;;
+&#125;</font></pre>
+<p>The paradigm for getting the data is that it's like reading a file. For every 
+  line, we check first whether we have reached the end-of-file (EOF). While not 
+  end-of-file, loop through each field in the row. Then move to the next line 
+  (MoveNext) and repeat. 
+<p>The <code>$result-&gt;fields[]</code> array is generated by the PHP database 
+  extension. Some database extensions do not index the array by field name. 
+  To force indexing by name - that is associative arrays - 
+  use the $ADODB_FETCH_MODE global variable. 
+<pre>
+	$<b>ADODB_FETCH_MODE</b> = ADODB_FETCH_NUM;
+	$rs1 = $db->Execute('select * from table');
+	$<b>ADODB_FETCH_MODE</b> = ADODB_FETCH_ASSOC;
+	$rs2 = $db->Execute('select * from table');
+	print_r($rs1->fields); // shows <i>array([0]=>'v0',[1] =>'v1')</i>
+	print_r($rs2->fields); // shows <i>array(['col1']=>'v0',['col2'] =>'v1')</i>
+</pre>
+<p>
+As you can see in the above example, both recordsets store and use different fetch modes
+based on the $ADODB_FETCH_MODE setting when the recordset was created by Execute().</p>
+<h2>ADOConnection<a name="ADOConnection"></a></h2>
+<p>Object that performs the connection to the database, executes SQL statements 
+  and has a set of utility functions for standardising the format of SQL statements 
+  for issues such as concatenation and date formats.</p>
+  
+<h3>Other Useful Functions</h3>
+<p><code>$recordset-&gt;Move($pos)</code> scrolls to that particular row. ADODB supports forward 
+  scrolling for all databases. Some databases will not support backwards scrolling. 
+  This is normally not a problem as you can always cache records to simulate backwards 
+  scrolling. 
+<p><code>$recordset-&gt;RecordCount()</code> returns the number of records accessed by the 
+  SQL statement. Some databases will return -1 because it is not supported. 
+<p><code>$recordset-&gt;GetArray()</code> returns the result as an array. 
+<p><code>rs2html($recordset)</code> is a function that is generates a HTML table based on the 
+  $recordset passed to it. An example with the relevant lines in bold:
+<pre>   include('adodb.inc.php'); 
+   <b>include('tohtml.inc.php');</b> /* includes the rs2html function */
+   $conn = &amp;ADONewConnection('mysql'); 
+   $conn-&gt;PConnect('localhost','userid','password','database');
+   $rs = $conn-&gt;Execute('select * from table');
+  <b> rs2html($rs)</b>; /* recordset to html table */ </pre>
+<p>There are many other helper functions that are listed in the documentation available at <a href="http://php.weblogs.com/adodb_manual"><a href="http://php.weblogs.com/adodb_manual">http://php.weblogs.com/adodb_manual</a></a>. 
+<h2>Advanced Material</h2>
+<h3>Inserts and Updates </h3>
+<p>Let's say you want to insert the following data into a database. 
+<p><b>ID</b> = 3<br>
+  <b>TheDate</b>=mktime(0,0,0,8,31,2001) /* 31st August 2001 */<br>
+  <b>Note</b>= sugar why don't we call it off 
+<p>When you move to another database, your insert might no longer work.</p>
+<p>The first problem is that each database has a different default date format. 
+  MySQL expects YYYY-MM-DD format, while other databases have different defaults. 
+  ADODB has a function called DBDate() that addresses this issue by converting 
+  converting the date to the correct format.</p>
+<p>The next problem is that the <b>don't</b> in the Note needs to be quoted. In 
+  MySQL, we use <b>don\'t</b> but in some other databases (Sybase, Access, Microsoft 
+  SQL Server) we use <b>don''t. </b>The qstr() function addresses this issue.</p>
+<p>So how do we use the functions? Like this:</p>
+<pre>$sql = &quot;INSERT INTO table (id, thedate,note) values (&quot; 
+   . $<b>ID</b> . ','
+   . $db-&gt;DBDate($<b>TheDate</b>) .','
+   . $db-&gt;qstr($<b>Note</b>).&quot;)&quot;;
+$db-&gt;Execute($sql);</pre>
+<p>ADODB also supports <code>$connection-&gt;Affected_Rows()</code> (returns the 
+  number of rows affected by last update or delete) and <code>$recordset-&gt;Insert_ID()</code> 
+  (returns last autoincrement number generated by an insert statement). Be forewarned 
+  that not all databases support the two functions.<br>
+</p>
+<h3>MetaTypes</h3>
+<p>You can find out more information about each of the fields (I use the words 
+  fields and columns interchangebly) you are selecting by calling the recordset 
+  method <code>FetchField($fieldoffset)</code>. This will return an object with 
+  3 properties: name, type and max_length. 
+<pre>For example:</pre>
+<pre>$recordset = $conn-&gt;Execute(&quot;select adate from table&quot;);<br>$f0 = $recordset-&gt;FetchField(0);
+</pre>
+<p>Then <code>$f0-&gt;name</code> will hold <i>'adata'</i>, <code>$f0-&gt;type</code> 
+  will be set to '<i>date'</i>. If the max_length is unknown, it will be set to 
+  -1. 
+<p>One problem with handling different databases is that each database often calls 
+  the same type by a different name. For example a <i>timestamp</i> type is called 
+  <i>datetime</i> in one database and <i>time</i> in another. So ADODB has a special 
+  <code>MetaType($type, $max_length)</code> function that standardises the types 
+  to the following: 
+<p>C: character and varchar types<br>
+  X: text or long character (eg. more than 255 bytes wide).<br>
+  B: blob or binary image<br>
+  D: date<br>
+  T: timestamp<br>
+  L: logical (boolean)<br>
+  I: integer<br>
+  N: numeric (float, double, money) 
+<p>In the above date example, 
+<p><code>$recordset = $conn-&gt;Execute(&quot;select adate from table&quot;);<br>
+  $f0 = $recordset-&gt;FetchField(0);<br>
+  $type = $recordset-&gt;MetaType($f0-&gt;type, $f0-&gt;max_length);<br>
+  print $type; /* should print 'D'</code> */
+<p> 
+<p><b>Select Limit and Top Support</b> 
+<p>ADODB has a function called $connection->SelectLimit($sql,$nrows,$offset) that allows
+you to retrieve a subset of the recordset. This will take advantage of native
+SELECT TOP on Microsoft products and SELECT ... LIMIT with PostgreSQL and MySQL, and
+emulated if the database does not support it.
+<p><b>Caching Support</b> 
+<p>ADODB allows you to cache recordsets in your file system, and only requery the database
+server after a certain timeout period with $connection->CacheExecute($secs2cache,$sql) and 
+$connection->CacheSelectLimit($secs2cache,$sql,$nrows,$offset).
+<p><b>PHP4 Session Handler Support</b> 
+<p>ADODB also supports PHP4 session handlers. You can store your session variables 
+  in a database for true scalability using ADODB. For further information, visit 
+  <a href="http://php.weblogs.com/adodb-sessions"><a href="http://php.weblogs.com/adodb-sessions">http://php.weblogs.com/adodb-sessions</a></a>
+<h3>Commercial Use Encouraged</h3>
+<p>If you plan to write commercial PHP applications that you want to resell, you should consider ADODB. It has been released using the lesser GPL, which means you can legally include it in commercial applications, while keeping your code proprietary. Commercial use of ADODB is strongly encouraged! We are using it internally for this reason.<p>

+  <i>let's call the whole thing off</i>.<br>
+  <br>
+<pre>
+   Refrain 
+<br>
+        You say eether and I say eyether, 
+        You say neether and I say nyther; 
+        Eether, eyether, neether, nyther - 
+        Let's call the whole thing off ! 
+<br>
+        You like potato and I like po-tah-to,

+<br>
+But oh, if we call the whole thing off, then we must part. 
+And oh, if we ever part, then that might break my heart. 
+<br>
+        So, if you like pajamas and I like pa-jah-mas, 
+        I'll wear pajamas and give up pa-jah-mas. 
+        For we know we 
+        Need each other, so we 
+        Better call the calling off off. 
+        Let's call the whole thing off ! 
+<br>
+   Second Refrain 
+<br>
+        You say laughter and I say lawfter, 
+        You say after and I say awfter; 
+        Laughter, lawfter, after, awfter - 
+        Let's call the whole thing off !

+        You, sa's'parilla and I sa's'parella; 
+        Vanilla, vanella, choc'late, strawb'ry - 
+        Let's call the whole thing off ! 
+<br>
+But oh, if we call the whole thing off, then we must part. 
+And oh, if we ever part, then that might break my heart. 
+<br>
+        So, if you go for oysters and I go for ersters, 
+        I'll order oysters and cancel the ersters. 
+        For we know we 
+        Need each other, so we 
+        Better call the calling off off. 
+        Let's call the whole thing off !
