+ADOdb Date Library, part of the ADOdb abstraction library\r
+Download: http://php.weblogs.com/adodb_date_time_library\r
+\r
+PHP native date functions use integer timestamps for computations.\r
+Because of this, dates are restricted to the years 1901-2038 on Unix \r
+and 1970-2038 on Windows due to integer overflow for dates beyond \r
+those years. This library overcomes these limitations by replacing the \r
+native function's signed integers (normally 32-bits) with PHP floating \r
+point numbers (normally 64-bits).\r
+\r
+Dates from 100 A.D. to 3000 A.D. and later\r
+have been tested. The minimum is 100 A.D. as <100 will invoke the\r
+2 => 4 digit year conversion. The maximum is billions of years in the \r
+future, but this is a theoretical limit as the computation of that year \r
+would take too long with the current implementation of adodb_mktime().\r
+\r
+This library replaces native functions as follows:\r
+\r
+<pre> \r
+ getdate() with adodb_getdate()\r
+ date() with adodb_date() \r
+ gmdate() with adodb_gmdate()\r
+ mktime() with adodb_mktime()\r
+ gmmktime() with adodb_gmmktime()45\r
+</pre>\r
+ \r
+The parameters are identical, except that adodb_date() accepts a subset\r
+of date()'s field formats. Mktime() will convert from local time to GMT, \r
+and date() will convert from GMT to local time, but daylight savings is \r
+not handled currently.\r
+\r
+This library is independant of the rest of ADOdb, and can be used\r
+as standalone code.\r
+\r
+PERFORMANCE\r
+\r
+For high speed, this library uses the native date functions where\r
+possible, and only switches to PHP code when the dates fall outside \r
+the 32-bit signed integer range.\r
+\r
+GREGORIAN CORRECTION\r
+\r
+Pope Gregory shortened October of A.D. 1582 by ten days. Thursday, \r
+October 4, 1582 (Julian) was followed immediately by Friday, October 15, \r
+1582 (Gregorian). \r
+\r
+Since 0.06, we handle this correctly, so:\r
+\r
+adodb_mktime(0,0,0,10,15,1582) - adodb_mktime(0,0,0,10,4,1582) \r
+ == 24 * 3600 (1 day)\r

+\r
+FUNCTION DESCRIPTIONS\r
+\r
+\r
+FUNCTION adodb_getdate($date=false)\r
+\r
+Returns an array containing date information, as getdate(), but supports\r
+dates greater than 1901 to 2038.\r
+\r
+\r
+FUNCTION adodb_date($fmt, $timestamp = false)\r
+\r
+Convert a timestamp to a formatted local date. If $timestamp is not defined, the\r
+current timestamp is used. Unlike the function date(), it supports dates\r
+outside the 1901 to 2038 range.\r
+\r
+The format fields that adodb_date supports:\r
+\r
+<pre>\r
+a - "am" or "pm" \r
+A - "AM" or "PM" \r
+d - day of the month, 2 digits with leading zeros; i.e. "01" to "31" \r
+D - day of the week, textual, 3 letters; e.g. "Fri" \r
+F - month, textual, long; e.g. "January" \r
+g - hour, 12-hour format without leading zeros; i.e. "1" to "12" \r
+G - hour, 24-hour format without leading zeros; i.e. "0" to "23" \r
+h - hour, 12-hour format; i.e. "01" to "12" \r
+H - hour, 24-hour format; i.e. "00" to "23" \r
+i - minutes; i.e. "00" to "59" \r
+j - day of the month without leading zeros; i.e. "1" to "31" \r
+l (lowercase 'L') - day of the week, textual, long; e.g. "Friday" \r
+L - boolean for whether it is a leap year; i.e. "0" or "1" \r
+m - month; i.e. "01" to "12" \r
+M - month, textual, 3 letters; e.g. "Jan" \r
+n - month without leading zeros; i.e. "1" to "12" \r
+O - Difference to Greenwich time in hours; e.g. "+0200" \r
+r - RFC 822 formatted date; e.g. "Thu, 21 Dec 2000 16:01:07 +0200" \r
+s - seconds; i.e. "00" to "59" \r
+S - English ordinal suffix for the day of the month, 2 characters; \r
+ i.e. "st", "nd", "rd" or "th" \r
+t - number of days in the given month; i.e. "28" to "31"\r
+T - Timezone setting of this machine; e.g. "EST" or "MDT" \r
+U - seconds since the Unix Epoch (January 1 1970 00:00:00 GMT) \r
+w - day of the week, numeric, i.e. "0" (Sunday) to "6" (Saturday) \r
+Y - year, 4 digits; e.g. "1999" \r
+y - year, 2 digits; e.g. "99" \r
+z - day of the year; i.e. "0" to "365" \r
+Z - timezone offset in seconds (i.e. "-43200" to "43200"). \r
+ The offset for timezones west of UTC is always negative, \r
+ and for those east of UTC is always positive. \r
+</pre>\r
+\r
+Unsupported:\r
+<pre>\r
+B - Swatch Internet time \r
+I (capital i) - "1" if Daylight Savings Time, "0" otherwise.\r
+W - ISO-8601 week number of year, weeks starting on Monday \r
+\r
+</pre>\r
+\r
+\r
+FUNCTION adodb_gmdate($fmt, $timestamp = false)\r
+\r
+Convert a timestamp to a formatted GMT date. If $timestamp is not defined, the\r
+current timestamp is used. Unlike the function date(), it supports dates\r
+outside the 1901 to 2038 range.\r
+\r
+\r
+FUNCTION adodb_mktime($hr, $min, $sec, $month, $day, $year)\r
+\r
+Converts a local date to a unix timestamp. Unlike the function mktime(), it supports\r
+dates outside the 1901 to 2038 range. Differs from mktime() in that all parameters\r
+are currently compulsory.\r
+\r
+FUNCTION adodb_gmmktime($hr, $min, $sec, $month, $day, $year)\r
+\r
+Converts a gmt date to a unix timestamp. Unlike the function gmmktime(), it supports\r
+dates outside the 1901 to 2038 range. Differs from gmmktime() in that all parameters\r
+are currently compulsory.\r
+\r
+=============================================================================\r
+\r
+NOTES\r
+\r
+Useful url for generating test timestamps:\r
+ http://www.4webhelp.net/us/timestamp.php\r
+\r
+Possible future optimizations include \r
+\r
+a. Using an algorithm similar to Plauger's in "The Standard C Library" \r
+(page 428, xttotm.c _Ttotm() function). Plauger's algorithm will not \r
+work outside 32-bit signed range, so i decided not to implement it.\r
+\r
+b. Iterate over a block of years (say 12) when searching for the \r
+correct year.\r
+\r
+c. Implement daylight savings, which looks awfully complicated, see\r
+ http://webexhibits.org/daylightsaving/\r
+\r
+\r
+CHANGELOG\r
+- 3 March 2003 0.08\r
+Added support for 'S' adodb_date() format char. Added constant ADODB_ALLOW_NEGATIVE_TS\r
+if you want PHP to handle negative timestamps between 1901 to 1969.\r
+\r
+- 27 Feb 2003 0.07\r
+All negative numbers handled by adodb now because of RH 7.3+ problems.\r
+See http://bugs.php.net/bug.php?id=20048&edit=2\r
+\r
+- 4 Feb 2003 0.06\r
+Fixed a typo, 1852 changed to 1582! This means that pre-1852 dates\r
+are now correctly handled.\r
+\r
+- 29 Jan 2003 0.05\r
+\r
+Leap year checking differs under Julian calendar (pre 1582). Also\r
+leap year code optimized by checking for most common case first.\r
+\r
+We also handle month overflow correctly in mktime (eg month set to 13).\r
+\r
+Day overflow for less than one month's days is supported.\r
+\r
+- 28 Jan 2003 0.04\r
+\r
+Gregorian correction handled. In PHP5, we might throw an error if \r
+mktime uses invalid dates around 5-14 Oct 1582. Released with ADOdb 3.10.\r
+Added limbo 5-14 Oct 1582 check, when we set to 15 Oct 1582.\r
+\r
+- 27 Jan 2003 0.03\r
+\r
+Fixed some more month problems due to gmt issues. Added constant ADODB_DATE_VERSION.\r
+Fixed calculation of days since start of year for <1970. \r
+\r
+- 27 Jan 2003 0.02\r
+\r
+Changed _adodb_getdate() to inline leap year checking for better performance.\r
+Fixed problem with time-zones west of GMT +0000.\r

-GNU LESSER GENERAL PUBLIC LICENSE\r
-Version 2.1, February 1999 \r
- \r
-Copyright (C) 1991, 1999 Free Software Foundation, Inc.\r
-59 Temple Place, Suite 330, Boston, MA 02111-1307 USA\r
-Everyone is permitted to copy and distribute verbatim copies\r
-of this license document, but changing it is not allowed.\r
-\r
-[This is the first released version of the Lesser GPL. It also counts\r
- as the successor of the GNU Library Public License, version 2, hence\r
- the version number 2.1.]\r
- \r
- \r
-Preamble\r
-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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-\r
-TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION\r
-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". \r
-\r
-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. \r
-\r
-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".) \r
-\r
-"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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-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: \r
-\r
-\r
-a) The modified work must itself be a software library. \r
-b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. \r
-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. \r
-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. \r
-(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.) \r
-\r
-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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-This option is useful when you wish to copy part of the code of the Library into a program that is not a library. \r
-\r
-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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-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.) \r
-\r
-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. \r
-\r
-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. \r
-\r
-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: \r
-\r
-\r
-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.) \r
-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. \r
-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. \r
-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. \r
-e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. \r
-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. \r
-\r
-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. \r
-\r
-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: \r
-\r
-\r
-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. \r
-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. \r
-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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. \r
-\r
-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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-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. \r
-\r
-NO WARRANTY \r
-\r

+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.

<pre>\r

+useful if you are calling black-box functions in which SQL queries might be executed.\r
+ Also all BeginTrans, CommitTrans and RollbackTrans calls inside a StartTrans block \r
+ will be disabled, so even if the black box function does a commit, it will be ignored.\r
+<pre>\r
+$DB->StartTrans();\r
+CallBlackBox();\r
+$DB->Execute("update table1 set val=$val1 where id=$id");\r
+$DB->Execute("update table2 set val=$val2 where id=$id");\r

+ Returns true on commit, false on rollback. If the parameter $autoComplete is true\r
+ monitor sql errors and commit and rollback as appropriate. Set $autoComplete to false \r
+ to force rollback even if no SQL error detected.\r
+<p><b>BeginTrans<a name="begintrans"></a>( )</b></p>\r

<p>You can also use the ADOdb <a href=#errorhandling>error handler</a> to die \r
and rollback your transactions for you transparently. Some buggy database extensions \r
are known to commit all outstanding tranasactions, so you might want to explicitly \r
<p>Since ADOdb 2.50, you are able to detect when you are inside a transaction. Check\r
that $connection->transCnt > 0. This variable is incremented whenever BeginTrans() is called,\r

+<p><b>3.40 ?? March 2003</b></p>\r
+<p>Modified postgresql UpdateBlobFile() because it did not work in safe mode.\r
+<p>Now connection object is passed to raiseErrorFn as last parameter. Needed by StartTrans().\r
+<p>Added StartTrans() and CompleteTrans(). It is recommended that you do not modify transOff, but\r
+use the above functions.\r
+<p>oci8po now obeys ADODB_ASSOC_CASE settings.\r
+<p>Added virtualized error codes, using PEAR DB equivalents. Requires you to manually include\r
+ adodb-error.inc.php yourself, with MetaError() and MetaErrorMsg($errno).\r
+<p>GetRowAssoc for mysql and pgsql were flawed. Fix by Ross Smith.\r
+<p>Added to datadict types I1, I2, I4 and I8. Changed datadict type 'T' to map to\r
+timestamp instead of datetime for postgresql.\r
+<p>Error handling in ExecuteSQLArray(), adodb-datadict.inc.php did not work. \r
+<p>We now auto-quote postgresql connection parameters when building connection string.\r
+<p>Added session expiry notification.\r
+<p>We now test with odbc mysql - made some changes to odbc recordset constructor.\r
+<p>MetaColumns now special cases access and other databases for odbc.\r
+<p><b>3.31 17 March 2003</b></p>\r
+<p>Added row checking for _fetch in postgres.\r
+<p>Added Interval type to MetaType for postgres.\r
+<p>Remapped postgres driver to call postgres7 driver internally.\r
+<p>Adorecordset_array::getarray() did not return array when nRows >= 0.\r
+<p>Postgresql: at times, no error message returned by pg_result_error()\r
+ but error message returned in pg_last_error(). Recoded again.\r
+<p>Interbase blob's now use chunking for updateblob.\r
+<p>Move() did not set EOF correctly. Reported by Jorma T.\r
+<p>We properly support mysql timestamp fields when we are creating mysql\r
+ tables using the data-dict interface.\r
+<p>Table regex includes backticks character now.\r
+<p><b>3.30 3 March 2003</b></p>\r
+<p>Added $ADODB_EXTENSION and $ADODB_COMPAT_FETCH constant.\r
+<p>Made blank1stItem configurable using syntax "value:text" in GetMenu/GetMenu2. Thx to Gabriel Birke.\r
+<p>Previously ADOdb differed from the Microsoft standard because it did not define \r
+ what to set $this->fields when EOF was reached. Now at EOF, ADOdb sets $this->fields \r
+ to false for all databases, which is consist with Microsoft's implementation. \r
+ Postgresql and mysql have always worked this way (in 3.11 and earlier). If \r
+ you are experiencing compatibility problems (and you are not using postgresql \r
+ nor mysql) on upgrading to 3.30, try setting the global variables $ADODB_COUNTRECS \r
+ = true (which is the default) and $ADODB_FETCH_COMPAT = true (this is a new \r
+ global variable). \r
+<p>We now check both pg_result_error and pg_last_error as sometimes pg_result_error does not display anything.\r
+ Iman Mayes \r
+<p>\r
+We no longer check for magic quotes gpc in Quote().\r
+<p>\r
+Misc fixes for table creation in adodb-datadict.inc.php. Thx to iamsure.\r
+<p>\r
+Time calculations use adodb_time library for all negative timestamps\r
+due to problems in Red Hat 7.3 or later. Formerly, only did this for \r
+Windows.\r
+<p>\r
+In mssqlpo, we now check if $sql in _query is a string before we change || to +. This is\r
+to support prepared stmts.\r
+<p>\r
+Move() and MoveLast() internals changed to support to support EOF and $this->fields change.\r
+<p>\r
+Added ADODB_FETCH_BOTH support to mssql. Thx to Angel Fradejas afradejas#mediafusion.es\r
+<p>\r
+We now check if link resource exists before we run mysql_escape_string in qstr().\r
+<p>\r
+Before we flock in csv code, we check that it is not a http url.\r
+<p><b>3.20 17 Feb 2003</b></p>\r
+<p>Added new Data Dictionary classes for creating tables and indexes. Warning - this is very much alpha quality code.\r
+The API can still change. See adodb/tests/test-datadict.php for more info.\r
+<p>We now ignore $ADODB_COUNTRECS for mysql, because PHP truncates incomplete recordsets \r
+ when mysql_unbuffered_query() is called a second time.\r
+<p>Now postgresql works correctly when $ADODB_COUNTRECS = false.\r
+<p>Changed _adodb_getcount to properly support SELECT DISTINCT.\r
+<p>Discovered that $ADODB_COUNTRECS=true has some problems with prepared queries - suspect\r
+PHP bug.\r
+<p>Now GetOne and GetRow run in $ADODB_COUNTRECS=false mode for better performance.\r
+<p>Added support for mysql_real_escape_string() and pg_escape_string() in qstr().\r
+<p>Added an intermediate variable for mysql _fetch() and MoveNext() to store fields, to prevent\r
+overwriting field array with boolean when mysql_fetch_array() returns false.\r
+<p>Made arrays for getinsertsql and getupdatesql case-insensitive. Suggested by Tim Uckun" tim#diligence.com\r
+<p><b>3.11 11 Feb 2003</b></p>\r
+<p>Added check for ADODB_NEVER_PERSIST constant in PConnect(). \r
+If defined, then PConnect() will actually call non-persistent Connect().\r
+<p>Modified interbase to properly work with Prepare().\r
+<p>Added $this->ibase_timefmt to allow you to change the date and time format.\r
+<p>Added support for $input_array parameter in CacheFlush().\r
+<p>Added experimental support for dbx, which was then removed when i found that\r
+it was slower than using native calls.\r
+<p>Added MetaPrimaryKeys for mssql and ibase/firebird.\r
+<p>Added new $trim parameter to GetCol and CacheGetCol\r
+<p>Uses updated adodb-time.inc.php 0.06.\r
+<p><b>3.10 27 Jan 2003</b>\r
+<p>Added adodb_date(), adodb_getdate(), adodb_mktime() and adodb-time.inc.php.\r
+<p>For interbase, added code to handle unlimited number of bind parameters. \r
+From Daniel Hasan daniel#hasan.cl.\r
+<p>Added BlobDecode and UpdateBlob for informix. Thx to Fernando Ortiz.\r
+<p>Added constant ADODB_WINDOWS. If defined, means that running on Windows.\r
+<p>Added constant ADODB_PHPVER which stores php version as a hex num. Removed $ADODB_PHPVER variable.\r
+<p>Felho Bacsi reported a minor white-space regular expression problem in GetInsertSQL.\r
+<p>Modified ADO to use variant to store _affectedRows\r
+<p>Changed ibase to use base class Replace(). Modified base class Replace() to support ibase.\r
+<p>Changed odbc to auto-detect when 0 records returned is wrong due to bad odbc drivers.\r
+<p>Changed mssql to use datetimeconvert ini setting only when 4.30 or later (does not work in 4.23).\r
+<p>ExecuteCursor($stmt, $cursorname, $params) now accepts a new $params array of additional bind \r
+parameters -- William Lovaton walovaton#yahoo.com.mx.\r
+<p>Added support for sybase_unbuffered_query if ADODB_COUNTRECS == false. Thx to chuck may.\r
+<p>Fixed FetchNextObj() bug. Thx to Jorma Tuomainen.\r
+<p>We now use SCOPE_IDENTITY() instead of @@IDENTITY for mssql - thx to marchesini#eside.it\r
+<p>Changed postgresql movenext logic to prevent illegal row number from being passed to pg_fetch_array().\r
+<p>Postgresql initrs bug found by "Bogdan RIPA" bripa#interakt.ro $f1 accidentally named $f\r
+<p><b>3.00 6 Jan 2003</b>\r

+<p>Added sql to retrive table and column info for odbc_mssql.\r
+<p><strong>2.91 3 Jan 2003</strong>\r
+<p>Revised PHP version checking to use $ADODB_PHPVER with legal values 0x4000, 0x4050, 0x4200, 0x4300.\r
+<p>Added support for bytea fields and oid blobs in postgres by allowing BlobDecode() \r

+<p>MetaColumns() max_length should use precision for types X and C for ms access. Fixed.\r
+<p>Speedup of odbc non-SELECT sql statements.\r
+<p>Added support in MetaColumns for Wide Char types for ODBC. We halve max_length \r

+<p>Added 'B' to types handled by GetUpdateSQL/GetInsertSQL.\r
+<p>Fixed warning message in oci8 driver with $persist variable when using PConnect.\r
+<p><b>2.90 11 Dec 2002</b>\r
+<p>Mssql and mssqlpo and oci8po now support ADODB_ASSOC_CASE. \r
+<p>Now MetaType() can accept a field object as the first parameter. \r

and is backward compatible. Suggested by Heinz Hombergs heinz#hhombergs.de.\r
<p>Fixed postgresql MoveNext() problems when called repeatedly after EOF. \r
<p>Added render_pagelinks to adodb-pager.inc.php. Code by "Pablo Costa" pablo#cbsp.com.br.\r
<p>MetaType() speedup in adodb.inc.php by using hashing instead of switch. Best performance\r
if constant arrays are supported, as they are in PHP5.\r
-<p>adodb-session.php now updates only the expiry date if the crc32 check indicates that the data\r
-has not been modified.\r
-<p><b>2.31 20 Aug 2002</b></p>\r

-Formerly we only used crc32().\r
-<p>Informix SelectLimit() problem with $ADODB_COUNTRECS fixed.\r
-<p>Fixed informix SELECT FIRST x DISTINCT, and not SELECT DISTINCT FIRST x - reported by F Riosa\r
-<p>Now default adodb error handlers ignores error if @ used.\r
-<p>If you set $conn->autoRollback=true, we auto-rollback persistent connections for odbc, mysql, oci8, mssql. \r
-Default for autoRollback is false. No need to do so for postgres. \r
-As interbase requires a transaction id (what a flawed api), we don't do it for interbase.\r

-<p>Karsten Kraus (Karsten.Kraus#web.de), contributed error-handling code to ADONewConnection. \r
- Unfortunately due to backward compat problems, had to rollback most of the changes.\r
-<p>Added new parameter to GetAssoc() to allow returning an array of key-value pairs, \r
-ignoring any additional columns in the recordset. Off by default.\r
-<p>Corrected mssql $conn->sysDate to return only date using convert().\r
-<p>CacheExecute() improved debugging output.\r
-<p>Changed rs2html() so newlines are converted to BR tags. Also optimized rs2html() based\r

-<p>Changed maxblobsize for odbc to default to 64000.\r
-<p><b>2.00 13 May 2002</b></p>\r
-<p>Added drivers <i>informix72</i> for pre-7.3 versions, and <i>oci805</i> for \r
- oracle 8.0.5, and postgres64 for postgresql 6.4 and earlier. The postgres and postgres7 drivers\r
- are now identical.\r
-<p>Interbase now partially supports ADODB_FETCH_BOTH, by defaulting to ASSOC mode.\r
-<p>Proper support for blobs in mssql. Also revised blob support code \r
-is base class. Now UpdateBlobFile() calls UpdateBlob() for consistency.\r
-<p>Added support for changed odbc_fetch_into api in php 4.2.0 \r
-with $conn->_has_stupid_odbc_fetch_api_change.\r
-<p>Fixed spelling of tablock locking hint in GenID( ) for mssql. \r
-<p>Added RowLock( ) to several databases, including oci8, informix, sybase, etc. \r
- Fixed where error in mssql RowLock().\r
-<p>Added sysDate and sysTimeStamp properties to most database drivers. These are the sql\r

-are useful for portable inserts and updates.\r
-<p>Support for RecordCount() caused date handling in sybase and mssql to break. \r
-Fixed, thanks to Toni Tunkkari, by creating derived classes for ADORecordSet_array for\r
-both databases. Generalized using arrayClass property. Also to support RecordCount(), \r
-changed metatype handling for ado drivers. Now the type returned in FetchField \r
- is no longer a number, but the 1-char data type returned by MetaType.\r

-<p>Experimental RowLock($table,$where) for mssql.\r
-<p>Properly implemented Prepare() in oci8 and ODBC.\r
-<p>Added Bind() support to oci8 to support Prepare().\r
-<p>Improved error handler. Catches CacheExecute() and GenID() errors now.\r
-<p>Now if you are running php from the command line, debugging messages do not output html formating.\r
-Not 100% complete, but getting there.\r
-<p><b>1.81 22 March 2002</b></p>\r
-<p>Restored default $ADODB_FETCH_MODE = ADODB_FETCH_DEFAULT for backward compatibility.\r

-CacheSelectLimit(), the secs2cache is still compulsory - sigh.\r
-<p>Sybase SQL Anywhere driver (using ODBC) contributed by Wade Johnson wade#wadejohnson.de\r
-<p><b>1.72 8 March 2002</b></p>\r

- when supporting new ADODB_FETCH_MODEs.\r
- <p>Mattia Rossi (mattia#technologist.com) contributed BlobDecode() and UpdateBlobFile() for postgresql\r
- using the postgres specific pg_lo_import()/pg_lo_open() - i don't use them but hopefully others will\r
- find this useful. See <a href="http://phplens.com/lens/lensforum/msgs.php?id=1262">this posting</a>\r
- for an example of usage.\r
- <p>Added UpdateBlobFile() for uploading files to a database.\r
- <p>Made UpdateBlob() compatible with oci8po driver.\r
- <p>Added noNullStrings support to oci8 driver. Oracle changes all ' ' strings to nulls,\r
- so you need to set strings to ' ' to prevent the nullifying of strings. $conn->noNullStrings = true;\r

-<p>Mssql date regex had error. Fixed - reported by Minh Hoang vb_user#yahoo.com.\r
-<p>DBTimeStamp() and DBDate() now accept iso dates and unix timestamps. This means\r
-that the PostgreSQL handling of dates in GetInsertSQL() and GetUpdateSQL() can\r
-be removed. Also if these functions are passed '' or null or false, we return a SQL null.\r
-<p>GetInsertSQL() and GetUpdateSQL() now accept a new parameter, $magicq to \r
-indicate whether quotes should be inserted based on magic quote settings - suggested by\r
-dj#4ict.com.\r
-<p>Reformated docs slightly based on suggestions by Chris Small.\r
- <p><b>1.65 28 Dec 2001</b></p>\r
- <p>Fixed borland_ibase class naming bug.\r
- <p>Now instead of using $rs->fields[0] internally, we use reset($rs->fields) so \r
- that we are compatible with ADODB_FETCH_ASSOC mode. Reported by Nico S.\r
- <p>Changed recordset constructor and _initrs() for oci8 so that it returns the field definitions even\r
- if no rows in the recordset. Reported by Rick Hickerson (rhickers#mv.mv.com).\r

-\r
-<p><b>1.62 11 Dec 2001</b></p>\r
-<p>Major speedup of ADOdb for low-end web sites by reducing the php code loading and compiling\r
-cycle. We conditionally compile not so common functions. \r
-Moved csv code to adodb-csvlib.inc.php to reduce adodb.inc.php parsing. This file\r
-is loaded only when the csv/proxy driver is used, or CacheExecute() is run.\r
-Also moved PageExecute(), GetSelectSQL() and GetUpdateSQL() core code to adodb-lib.inc.php.\r
-This reduced the 70K main adodb.inc.php file to 55K, and since at least 20K of the file\r
-is comments, we have reduced 50K of code in adodb.inc.php to 35K. There\r
- should be 35% reduction in memory and thus 35% speedup in compiling the php code for the\r
-main adodb.inc.php file.\r
-<p>Highly tuned SelectLimit() for oci8 for massive speed improvements on large files. \r
-Selecting 20 rows starting from the 20,000th row of a table is now 7 times faster. \r
-Thx to Tomas V V Cox.\r
-<p>Allow . and # in table definitions in GetInsertSQL and GetUpdateSQL.\r
- See ADODB_TABLE_REGEX constant. Thx to Ari Kuorikoski.\r
-<p>Added ADODB_PREFETCH_ROWS constant, defaulting to 10. This determines the number\r
-of records to prefetch in a SELECT statement. Only used by oci8.</p>\r
-<p>Added high portability Oracle class called oci8po. This uses ? for bind variables, and \r
-lower cases column names.</p>\r
-<p>Now all database drivers support $ADODB_FETCH_MODE, including interbase, ado, and odbc:\r
-ADODB_FETCH_NUM and ADODB_FETCH_ASSOC. ADODB_FETCH_BOTH is not fully implemented for all \r
-database drivers.\r
-<p><b>1.61 Nov 2001</b></p>\r
-<p>Added PO_RecordCount() and PO_Insert_ID(). PO stands for portable. Pablo Roca \r
- [pabloroca#mvps.org]</p>\r

- for availability.</p>\r
-<p>M'soft ADO we now correctly close recordset in _close() peterd#telephonetics.co.uk</p>\r
-<p>MSSQL now supports GenID(). It generates a 16-byte GUID from mssql newid() \r
- function.</p>\r
-<p>Changed ereg_replace to preg_replace in SelectLimit. This is a fix for mssql. \r
- Ereg doesn't support t or n! Reported by marino Carlos xaplo#postnuke-espanol.org</p>\r
-<p>Added $recordset->connection. This is the ADOConnection object for the recordset. \r
-Works with cached and normal recordsets. Surprisingly, this had no affect on performance!</p>\r
-<p><b>1.54 15 Nov 2001</b></p>\r
-Fixed some more bugs in PageExecute(). I am getting sick of bug in this and will have to \r
-reconsider my QA here. The main issue is that I don't use PageExecute() and \r
-to check whether it is working requires a visual inspection of the html generated currently.\r
-It is possible to write a test script but it would be quite complicated :(\r
-<p> More speedups of SelectLimit() for DB2, Oci8, access, vfp, mssql.\r
-<p>\r
-\r
-<p><b>1.53 7 Nov 2001</b></p>\r

-<p>Removed postgres pconnect debugging statement.\r
-<p><b>1.50 31 Oct 2001</b></p>\r
-<p>ADOdbConnection renamed to ADOConnection, and ADOdbFieldObject to ADOFieldObject.\r
-<p>PageExecute() now checks for empty $rs correctly, and the errors in the docs on this subject have been fixed.\r
-<p>odbc_error() does not return 6 digit error correctly at times. Implemented workaround.\r
-<p>Added ADORecordSet_empty class. This will speedup INSERTS/DELETES/UPDATES because the return\r
-object created is much smaller.\r
-<p>Added Prepare() to odbc, and oci8 (but doesn't work properly for oci8 still).\r
-<p>Made pgsql a synonym for postgre7, and changed SELECT LIMIT to use OFFSET for compat with \r
-postgres 7.2.\r
-<p>Revised adodb-cryptsession.php thanks to Ari.\r
-<p>Set resources to false on _close, to force freeing of resources.\r
-<p>Added adodb-errorhandler.inc.php, adodb-errorpear.inc.php and raiseErrorFn on Freek's urging.\r
-<p>GetRowAssoc($toUpper=true): $toUpper added as default.\r
-<p>Errors when connecting to a database were not captured formerly. Now we do it correctly.\r

-<p>rs2html() now pretty printed.\r
-<p>Jonathan Younger jyounger#unilab.com contributed the great idea GetUpdateSQL() and GetInsertSQL() which\r
-generates SQL to update and insert into a table from a recordset. Modify the recordset fields\r
-array, then can this function to generate the SQL (the SQL is not executed).\r
-<p>"Nicola Fankhauser" <nicola.fankhauser#couniq.com> found some bugs in date handling for mssql.</p>\r
-<p>Added minimal Oracle support for LOBs. Still under development.</p>\r
-Added $ADODB_FETCH_MODE so you can control whether recordsets return arrays which are\r
-numeric, associative or both. This is a global variable you set. Currently only MySQL, Oci8, Postgres\r

-<p>Misc fixes to SelectLimit() to support Access (top must follow distinct) and Fields() \r
-in the array recordset. From Reinhard Balling.</p>\r
-<p><b>0.96 27 Mar 2001</b></p>\r
-<p>ADOConnection Close() did not return a value correctly. Thanks to akul#otamedia.com.</p>\r
-<p>When the horrible magic_quotes is enabled, back-slash () is changed to double-backslash (\).\r

-<p>Also many PostgreSQL changes by Freek. He almost rewrote the whole PostgreSQL driver!</p>\r
-<p>Added fix to input parameters in Execute for non-strings by Ron Baldwin.</p>\r
-<p>Added new metatype, X for TeXt. Formerly, metatype B for Blob also included\r
-text fields. Now 'B' is for binary/image data. 'X' for textual data.</p>\r

+\r
+USAGE:\r
+\r
+ // First create a normal connection\r
+ $db->NewADOConnection('mysql');\r
+ $db->Connect(...);\r
+ \r
+ // Then create a data dictionary object, using this connection\r
+ $dict = NewDataDictionary($db);\r
+ \r
+ // We demonstrate creating tables and indexes\r
+ $sqlarray = $dict->CreateTableSQL($tabname, $fldarray, $taboptarray);\r
+ $dict->ExecuteSQLArray($sqlarray);\r
+ \r
+ $sqlarray = $dict->CreateIndexSQL($idxname, $tabname, $flds);\r
+ $dict->ExecuteSQLArray($sqlarray);\r
+ \r
+FUNCTIONS:\r
+\r
+ ========\r
+ function CreateDatabase($dbname, $optionsarray)\r
+ \r
+ \r
+ ========\r
+ function CreateTableSQL($tabname, $fldarray, $taboptarray=false)\r
+ \r
+ RETURNS: an array of strings, the sql to be executed, or false\r
+ $tabname: name of table\r
+ $fldarray: array containing field info\r
+ $taboptarray: array containing table options\r
+ \r
+ The format of $fldarray is a 2-dimensional array, where each row in the \r
+ 1st dimension represents one field. Each row has this format:\r
+ \r
+ array($fieldname, $type, [,$colsize] [,$otheroptions]*)\r
+ \r
+ The first 2 fields must be the field name and the field type. The field type\r
+ can be a portable type codes or the actual type for that database. \r
+ Legal portable type codes include:\r
+\r
+ C: varchar\r
+ X: CLOB (character large object) or largest varchar size \r
+ if CLOB is not supported\r
+ C2: Multibyte varchar\r
+ X2: Multibyte CLOB\r
+ \r
+ B: BLOB (binary large object)\r
+ \r
+ D: Date (some databases do not support this, and we return a datetime type)\r
+ T: Datetime or Timestamp\r
+ L: Integer field suitable for storing booleans (0 or 1)\r
+ I: Integer (mapped to I4)\r
+ I1: 1-byte integer\r
+ I2: 2-byte integer\r
+ I4: 4-byte integer\r
+ I8: 8-byte integer\r
+ F: Floating point number\r
+ N: Numeric or decimal number\r
+ \r
+ The $colsize field represents the size of the field. If a decimal number is \r
+ used, then it is assumed that the number following the dot is the precision,\r
+ so 6.2 means a number of size 6 digits and 2 decimal places. It is \r
+ recommended that the default for number types be represented as a string to \r
+ avoid any rounding errors.\r
+ \r
+ The $otheroptions include the following keywords (case-insensitive):\r
+\r
+ AUTO For autoincrement number. Emulated with triggers if not available.\r
+ Sets NOTNULL also.\r
+ AUTOINCREMENT Same as auto.\r
+ KEY Primary key field. Sets NOTNULL also. Compound keys are supported.\r
+ PRIMARY Same as KEY.\r
+ DEFAULT The default value. Character strings are auto-quoted unless\r
+ the string begins and ends with spaces, eg ' SYSDATE '.\r
+ NOTNULL If field is not null.\r
+ DEFDATE Set default value to call function to get today's date.\r
+ DEFTIMESTAMP Set default to call function to get today's datetime.\r
+ NOQUOTE Prevents autoquoting of default string values.\r
+ CONSTRAINTS Additional constraints defined at the end of the field\r
+ definition.\r
+ \r
+ Examples:\r
+ array('COLNAME', 'DECIMAL', '8.4', 'DEFAULT' => 0, 'NotNull')\r
+ array('ID', 'I' , 'AUTO')\r
+ array('MYDATE', 'D' , 'DEFDATE')\r
+ array('NAME', 'C' ,'32', \r
+ 'CONSTRAINTS' => 'FOREIGN KEY REFERENCES reftable')\r
+ \r
+ The $taboptarray is the 3rd parameter of the CreateTableSQL function. \r
+ This contains table specific settings. Legal keywords include\r
+ \r
+ REPLACE Indicates that the previous table definition should be removed\r
+ together with ALL data.\r
+ CONSTRAINTS Additional constraints defined for the whole table. You will\r
+ probably need to prefix this with a comma.\r
+ \r
+ Database specific table options can be defined also using the name of the\r
+ database type as the array key. For example:\r
+ \r
+ $taboptarray = array('mysql' => 'TYPE=ISAM', 'oci8' => 'tablespace users');\r
+ \r
+ You can also define foreignkey constraints. The following is syntax for \r
+ postgresql:\r
+ \r
+ $taboptarray = array('constraints' => \r
+ ', FOREIGN KEY (col1) REFERENCES reftable (refcol)');\r
+\r
+ \r
+ ========\r
+ function CreateIndexSQL($idxname, $tabname, $flds, $idxoptarray=false)\r
+ \r
+ RETURNS: an array of strings, the sql to be executed, or false\r
+ $idxname: name of index\r
+ $tabname: name of table\r
+ $fldarray: list of fields as a comma delimited string or an array of strings\r
+ $idxoptarray: array of index creation options\r
+ \r
+ $idxoptarray is similar to $taboptarray in that index specific information can\r
+ be embedded in the array. Other options include:\r
+ \r
+ CLUSTERED Create clustered index (only mssql)\r
+ BITMAP Create bitmap index (only oci8)\r
+ UNIQUE Make unique index\r
+ FULLTEXT Make fulltext index (only mysql)\r
+ HASH Create hash index (only postgres)\r
+ \r
+ ======== \r
+ function AddColumnSQL($tabname, $flds)\r
+ \r
+ ========\r
+ function AlterColumnSQL($tabname, $flds)\r
+ \r
+ ========\r
+ function DropColumnSQL($tabname, $flds)\r
+ \r
+ ========\r
+ function ExecuteSQLArray($sqlarray, $contOnError = true)\r
+ \r
+ RETURNS: 0 if failed, 1 if executed all but with errors, 2 if executed successfully\r
+ $sqlarray: an array of strings with sql code (no semicolon at the end of string)\r

- If you are writing an application that is used in multiple environments and \r
- operating systems, you need to plan to support multiple databases. This article \r
- is based on my experiences with multiple database systems, stretching from 4th \r
- Dimension in my Mac days, to the databases I currently use, which are: Oracle, \r
- FoxPro, Access, MS SQL Server and MySQL. Although most of the advice here applies \r
- to using SQL with Perl, Python and other programming languages, I will focus on PHP and how \r
- the <a href="http://php.weblogs.com/adodb">ADOdb</a> database abstraction library \r
- offers some solutions.<p></p>\r
-<p>Most database vendors practice product lock-in. The best or fastest way to \r
- do things is often implemented using proprietary extensions to SQL. This makes \r
- it extremely hard to write portable SQL code that performs well under all conditions. \r
- When the first ANSI committee got together in 1984 to standardize SQL, the database \r
- vendors had such different implementations that they could only agree on the \r
- core functionality of SQL. Many important application specific requirements \r
- were not standardized, and after so many years since the ANSI effort began, \r
- it looks as if much useful database functionality will never be standardized. \r
- Even though ANSI-92 SQL has codified much more, we still have to implement portability \r
- at the application level.</p>\r
-<h3><b>Selects</b></h3>\r
-<p>The SELECT statement has been standardized to a great degree. Nearly every \r
- database supports the following:</p>\r
-<p>SELECT [cols] FROM [tables]<br>\r
- [WHERE conditions]<br>\r
- [GROUP BY cols]<br>\r
- [HAVING conditions] <br>\r
- [ORDER BY cols]</p>\r
-<p>But so many useful techniques can only be implemented by using proprietary \r
- extensions. For example, when writing SQL to retrieve the first 10 rows for \r
- paging, you could write...</p>\r
-<table width="80%" border="1" cellspacing="0" cellpadding="0" align="center">\r
- <tr> \r
- <td><b>Database</b></td>\r
- <td><b>SQL Syntax</b></td>\r
- </tr>\r
- <tr> \r
- <td>DB2</td>\r
- <td>select * from table fetch first 10 rows only</td>\r
- </tr>\r
- <tr> \r
- <td>Informix</td>\r
- <td>select first 10 * from table</td>\r
- </tr>\r
- <tr> \r
- <td>Microsoft SQL Server and Access</td>\r
- <td>select top 10 * from table</td>\r
- </tr>\r
- <tr> \r
- <td>MySQL and PostgreSQL</td>\r
- <td>select * from table limit 10</td>\r
- </tr>\r
- <tr> \r
- <td>Oracle 8i</td>\r
- <td>select * from (select * from table) where rownum <= 10</td>\r
- </tr>\r
-</table>\r
-<p>This feature of getting a subset of data is so useful that in the PHP class \r
- library ADOdb, we have a SelectLimit( ) function that allows you to hide the \r
- implementation details within a function that will rewrite your SQL for you:</p>\r
-<pre>$connection->SelectLimit('select * from table', 10);\r
-</pre>\r
-<p><b>Selects: Fetch Modes</b></p>\r
-<p>PHP allows you to retrieve database records as arrays. You can choose to have \r
- the arrays indexed by field name or number. However different low-level PHP \r
- database drivers are inconsistent in their indexing efforts. ADOdb allows you \r
- to determine your prefered mode. You set this by setting the variable $ADODB_FETCH_MODE \r
- to either of the constants ADODB_FETCH_NUM (for numeric indexes) or ADODB_FETCH_ASSOC \r
- (using field names as an associative index).</p>\r
-<p>The default behaviour of ADOdb varies depending on the database you are using. \r
- For consistency, set the fetch mode to either ADODB_FETCH_NUM (for speed) or \r
- ADODB_FETCH_ASSOC (for convenience) at the beginning of your code. </p>\r
-<p><b>Selects: Counting Records</b></p>\r
-<p>Another problem with SELECTs is that some databases do not return the number \r
- of rows retrieved from a select statement. This is because the highest performance \r
- databases will return records to you even before the last record has been found. \r
-</p>\r
-<p>In ADOdb, RecordCount( ) returns the number of rows returned, or will emulate \r
- it by buffering the rows and returning the count after all rows have been returned. \r
- This can be disabled for performance reasons when retrieving large recordsets \r
- by setting the global variable $ADODB_COUNTRECS = false. This variable is checked \r
- every time a query is executed, so you can selectively choose which recordsets \r
- to count.</p>\r
-<p>If you prefer to set $ADODB_COUNTRECS = false, ADOdb still has the PO_RecordCount( \r
- ) function. This will return the number of rows, or if it is not found, it will \r
- return an estimate using SELECT COUNT(*):</p>\r
-<pre>$rs = $db->Execute("select * from table where state=$state");\r
-$numrows = $rs->PO_RecordCount('table', "state=$state");</pre>\r
-<p><b>Selects: Locking</b> </p>\r
-<p>SELECT statements are commonly used to implement row-level locking of tables. \r
- Other databases such as Oracle, Interbase, PostgreSQL and MySQL with InnoDB \r
- do not require row-level locking because they use versioning to display data \r
- consistent with a specific point in time.</p>\r
-<p>Currently, I recommend encapsulating the row-level locking in a separate function, \r
- such as RowLock($table, $where):</p>\r
-<pre>$connection->BeginTrans( );\r
-$connection->RowLock($table, $where); </pre>\r
-<pre><font color=green># some operation</font></pre>\r
-<pre>if ($ok) $connection->CommitTrans( );\r
-else $connection->RollbackTrans( );\r
-</pre>\r
-<p><b>Selects: Outer Joins</b></p>\r
-<p>Not all databases support outer joins. Furthermore the syntax for outer joins \r
- differs dramatically between database vendors. One portable (and possibly slower) \r
- method of implementing outer joins is using UNION.</p>\r
-<p>For example, an ANSI-92 left outer join between two tables t1 and t2 could \r
- look like:</p>\r
-<pre>SELECT t1.col1, t1.col2, t2.cola <br> FROM t1 <i>LEFT JOIN</i> t2 ON t1.col = t2.col</pre>\r
-<p>This can be emulated using:</p>\r
-<pre>SELECT t1.col1, t1.col2, t2.cola FROM t1, t2 <br> WHERE t1.col = t2.col \r
- UNION ALL\r
-SELECT col1, col2, null FROM t1 <br> WHERE t1.col not in (select distinct col from t2)\r
-</pre>\r
-<p>Since ADOdb 2.13, we provide some hints in the connection object as to legal \r
- join variations. This is still incomplete and sometimes depends on the database \r
- version you are using, but is useful as a general guideline:</p>\r
-<p><font face="Courier New, Courier, mono">$conn->leftOuter</font>: holds the \r
- operator used for left outer joins (eg. '*='), or false if not known or not \r
- available.<br>\r
- <font face="Courier New, Courier, mono">$conn->rightOuter</font>: holds the \r
- operator used for right outer joins (eg '=*'), or false if not known or not \r
- available.<br>\r
- <font face="Courier New, Courier, mono">$conn->ansiOuter</font>: boolean \r
- that if true means that ANSI-92 style outer joins are supported, or false if \r
- not known.</p>\r
-<h3><b>Inserts</b> </h3>\r
-<p>When you create records, you need to generate unique id's for each record. \r
- There are two common techniques: (1) auto-incrementing columns and (2) sequences. \r
-</p>\r
-<p>Auto-incrementing columns are supported by MySQL, Sybase and Microsoft Access \r
- and SQL Server. However most other databases do not support this feature. So \r
- for portability, you have little choice but to use sequences. Sequences are \r
- special functions that return a unique incrementing number every time you call \r
- it, suitable to be used as database keys. In ADOdb, we use the GenID( ) function. \r
- It has takes a parameter, the sequence name. Different tables can have different \r
- sequences. </p>\r
-<pre>$id = $connection->GenID('sequence_name');<br>$connection->Execute("insert into table (id, firstname, lastname) <br> values ($id, $firstname, $lastname)");</pre>\r
-<p>For databases that do not support sequences natively, ADOdb emulates sequences \r
- by creating a table for every sequence.</p>\r
-<h3><b>Binding</b></h3>\r
-<p>Binding variables in an SQL statement is another tricky feature. Binding is \r
- useful because it allows pre-compilation of SQL. When inserting multiple records \r
- into a database in a loop, binding can offer a 50% (or greater) speedup. However \r
- many databases such as Access and MySQL do not support binding natively and \r
- there is some overhead in emulating binding. Furthermore, different databases \r
- (specificly Oracle!) implement binding differently. My recommendation is to \r
- use binding if your database queries are too slow, but make sure you are using \r
- a database that supports it like Oracle. </p>\r
-<p>ADOdb supports portable Prepare/Execute with:</p>\r
-<pre>$stmt = $db->Prepare('select * from customers where custid=? and state=?');\r
-$rs = $db->Execute($stmt, array($id,'New York'));</pre>\r
-<h2>DDL and Tuning</h2>\r
-<p>There are database design tools such as ERWin or Dezign that allow you to generate \r
- data definition language commands such as ALTER TABLE or CREATE INDEX from Entity-Relationship \r
- diagrams. Other developers such as Manuel Lemos have developed portable XML \r
- based schemas for PHP with Metabase. I think this might suit many developers, \r
- but I prefer to manually define the database tables. This is because for high \r
- performance, the placement of tables and selection of the different types of \r
- indexes has to be planned based on the number of hard disks and the i/o characteristics \r
- of the data. This can only be done manually. Here are some tuning hints:</p>\r
-<ul>\r
- <li>The most important and frequently used tables deserve to be placed on their \r
- own separate hard disks. </li>\r
- <li>Indexes and data should be kept on different hard disks. </li>\r
- <li>Transaction logs and rollback segments deserve their own hard disks.</li>\r
- <li>Using Striping (RAID 5) is only useful when you rarely write to your database. \r
- Mirroring is a better compromise between reading and writing.</li>\r
- <li>Consider bypassing the file system and using raw disks.</li>\r
- <li>Make sure you have asynchronous IO enabled for your database and operating \r
- system.</li>\r
- <li>Be prepared to waste space. You probably need at least 5 hard disks for \r
- a high-performance database system:<br>\r
- - 1 hard disk for the operating system and temporary data, <br>\r
- - 1 for data,<br>\r
- - 1 for indexes, <br>\r
- - 1 for rollback, <br>\r
- - 1 for transaction logs.</li>\r
-</ul>\r
-<h3>Data Types</h3>\r
-<p>Stick to a few data types that are available in most databases. Char, varchar \r
- and numeric/number are supported by most databases. Most other data types (including \r
- integer, boolean and float) cannot be relied on being available. I recommend \r
- using char(1) or number(1) to hold booleans. </p>\r
-<p>Different databases have different ways of representing dates and timestamps/datetime. \r
- ADOdb attempts to display all dates in ISO (YYYY-MM-DD) format. ADOdb also provides \r
- DBDate( ) and DBTimeStamp( ) to convert dates to formats that are acceptable \r
- to that database. Both functions accept Unix integer timestamps and date strings \r
- in ISO format.</p>\r
-<pre>$date1 = $connection->DBDate(time( ));<br>$date2 = $connection->DBTimeStamp('2002-02-23 13:03:33');</pre>\r
-<p>We also provide functions to convert database dates to Unix timestamps:</p>\r
-<pre>$unixts = $recordset->UnixDate('#2002-02-30#'); <font color="green"># MS Access date => unix timestamp</font></pre>\r
-<p>The maximum length of a char/varchar field is also database specific. You can \r
- only assume that field lengths of up to 250 characters are supported. This is \r
- normally impractical for web based forum or content management systems. You \r
- will need to be familiar with how databases handle large objects (LOBs). ADOdb \r
- implements two functions, UpdateBlob( ) and UpdateClob( ) that allow you to \r
- update fields holding Binary Large Objects (eg. pictures) and Character Large \r
- Objects (eg. HTML articles):</p>\r
-<pre><font color=green># for oracle </font>\r
-$conn->Execute('INSERT INTO blobtable (id, blobcol) VALUES (1,empty_blob())'); \r
-$conn->UpdateBlob('blobtable','blobcol',$blobvalue,'id=1'); \r
- \r
-<font color=green># non-oracle databases</font>\r
-$conn->Execute('INSERT INTO blobtable (id, blobcol) VALUES (1, null)'); \r
-$conn->UpdateBlob('blobtable','blobcol',$blobvalue,'id=1');\r
-</pre>\r
-<p>Null handling is another area where differences can occur. This is a mine-field, \r
- because 3-value logic is tricky.\r
-<p>In general, I avoid using nulls except for dates and default all my numeric \r
- and character fields to 0 or the empty string. This maintains consistency with \r
- PHP, where empty strings and zero are treated as equivalent, and avoids SQL \r
- ambiguities when you use the ANY and EXISTS operators. However if your database \r
- has significant amounts of missing or unknown data, using nulls might be a good \r
- idea. \r
-<h3><b>Stored Procedures</b></h3>\r
-<p>Stored procedures are another problem area. Some databases allow recordsets \r
- to be returned in a stored procedure (Microsoft SQL Server and Sybase), and \r
- others only allow output parameters to be returned. Stored procedures sometimes \r
- need to be wrapped in special syntax. For example, Oracle requires such code \r
- to be wrapped in an anonymous block with BEGIN and END. Also internal sql operators \r
- and functions such as +, ||, TRIM( ), SUBSTR( ) or INSTR( ) vary between vendors. \r
-</p>\r
-<p>An example of how to call a stored procedure with 2 parameters and 1 return \r
- value follows:</p>\r
-<pre> switch ($db->databaseType) {\r
- case '<font color="#993300">mssql</font>':\r
- $sql = <font color="#000000"><font color="#993333">'<font color="#993300">SP_RUNSOMETHING</font>'</font></font>; break;\r
- case '<font color="#993300">oci8</font>':\r
- $sql = \r
-<font color="#993300"> </font><font color="#000000"><font color="#993300">"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;";\r
-</font> break;</font>\r
- default:\r
- die('<font color="#993300">Unsupported feature</font>');\r
- }\r
-<font color="#000000"><font color="green"> # @RETVAL = SP_RUNSOMETHING @myid,@group</font>\r
- $stmt = $db->PrepareSP($sql); <br> $db->Parameter($stmt,$id,'<font color="#993300">myid</font>'); \r
- $db->Parameter($stmt,$group,'<font color="#993300">group</font>');\r
- <font color="green"># true indicates output parameter<br> </font>$db->Parameter($stmt,$ret,'<font color="#993300">RETVAL</font>',true); \r
- $db->Execute($stmt); </font></pre>\r
-<p>As you can see, the ADOdb API is the same for both databases. But the stored \r
- procedure SQL syntax is quite different between databases and is not portable, \r
- so be forewarned! However sometimes you have little choice as some systems only \r
- allow data to be accessed via stored procedures. This is when the ultimate portability \r
- solution might be the only solution: <i>treating portable SQL as a localization \r
- exercise...</i></p>\r
-<h3><b>SQL as a Localization Exercise</b></h3>\r
-<p> In general to provide real portability, you will have to treat SQL coding \r
- as a localization exercise. In PHP, it has become common to define separate \r
- language files for English, Russian, Korean, etc. Similarly, I would suggest \r
- you have separate Sybase, Intebase, MySQL, etc files, and conditionally include \r
- the SQL based on the database. For example, each MySQL SQL statement would be \r
- stored in a separate variable, in a file called 'mysql-lang.inc.php'.</p>\r
-<pre>$sqlGetPassword = '<font color="#993300">select password from users where userid=%s</font>';\r
-$sqlSearchKeyword = "<font color="#993300">SELECT * FROM articles WHERE match (title,body) against (%s</font>)";</pre>\r
-<p>In our main PHP file:</p>\r
-<pre><font color=green># define which database to load...</font>\r
-<b>$database = '<font color="#993300">mysql</font>';\r
-include_once("<font color="#993300">$database-lang.inc.php</font>");</b>\r
-\r
-$db = &NewADOConnection($database);\r
-$db->PConnect(...) or die('<font color="#993300">Failed to connect to database</font>');\r
-\r
-<font color=green># search for a keyword $word</font>\r
-$rs = $db->Execute(sprintf($sqlSearchKeyWord,$db->qstr($word)));</pre>\r
-<p>Note that we quote the $word variable using the qstr( ) function. This is because \r
- each database quotes strings using different conventions.</p>\r
-<p>\r
-<h3>Final Thoughts</h3>\r
-<p>The best way to ensure that you have portable SQL is to have your data tables designed using \r
-sound principles. Learn the theory of normalization and entity-relationship diagrams and model \r
-your data carefully. Understand how joins and indexes work and how they are used to tune performance.\r

+<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 = $connection->GenID('sequence_name');<br>$connection->Execute("insert into table (id, firstname, lastname) <br> values ($id, $firstname, $lastname)");</pre>
+<p>For databases that do not support sequences natively, ADOdb emulates sequences
+ by creating a table for every sequence.</p>
+<h3><b>Binding</b></h3>
+<p>Binding variables in an SQL statement is another tricky feature. Binding is
+ useful because it allows pre-compilation of SQL. When inserting multiple records
+ into a database in a loop, binding can offer a 50% (or greater) speedup. However
+ many databases such as Access and MySQL do not support binding natively and
+ there is some overhead in emulating binding. Furthermore, different databases
+ (specificly Oracle!) implement binding differently. My recommendation is to
+ use binding if your database queries are too slow, but make sure you are using
+ a database that supports it like Oracle. </p>
+<p>ADOdb supports portable Prepare/Execute with:</p>
+<pre>$stmt = $db->Prepare('select * from customers where custid=? and state=?');
+$rs = $db->Execute($stmt, array($id,'New York'));</pre>
+<h2>DDL and Tuning</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 for high
+ performance, 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>Using Striping (RAID 5) is only useful when you rarely write to your database.
+ Mirroring is a better compromise between reading and writing.</li>
+ <li>Consider bypassing the file system and using raw disks.</li>
+ <li>Make sure you have asynchronous IO enabled for your database and operating
+ system.</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 = $connection->DBDate(time( ));<br>$date2 = $connection->DBTimeStamp('2002-02-23 13:03:33');</pre>
+<p>We also provide functions to convert database dates to Unix timestamps:</p>
+<pre>$unixts = $recordset->UnixDate('#2002-02-30#'); <font color="green"># MS Access date => unix timestamp</font></pre>
+<p>The maximum length of a char/varchar field is also database specific. You can
+ only assume that field lengths of up to 250 characters are supported. This is
+ normally impractical for web based forum or content management systems. You
+ will need to be familiar with how databases handle large objects (LOBs). ADOdb
+ implements two functions, UpdateBlob( ) and UpdateClob( ) that allow you to
+ update fields holding Binary Large Objects (eg. pictures) and Character Large
+ Objects (eg. HTML articles):</p>
+<pre><font color=green># for oracle </font>
+$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',$blobvalue,'id=1');
+</pre>
+<p>Null handling is another area where differences can occur. This is a mine-field,
+ because 3-value logic is tricky.
+<p>In general, I avoid using nulls except for dates and default all my numeric
+ and character fields to 0 or the empty string. This maintains consistency with
+ PHP, where empty strings and zero are treated as equivalent, and avoids SQL
+ ambiguities when you use the ANY and EXISTS operators. However if your database
+ has significant amounts of missing or unknown data, using nulls might be a good
+ idea.
+<h3><b>Stored Procedures</b></h3>
+<p>Stored procedures are another problem area. Some databases allow recordsets
+ to be returned in a stored procedure (Microsoft SQL Server and Sybase), and
+ others only allow output parameters to be returned. Stored procedures sometimes
+ need to be wrapped in special syntax. For example, Oracle requires such code
+ to be wrapped in an anonymous block with BEGIN and END. Also internal sql operators
+ and functions such as +, ||, TRIM( ), SUBSTR( ) or INSTR( ) vary between vendors.
+</p>
+<p>An example of how to call a stored procedure with 2 parameters and 1 return
+ value follows:</p>
+<pre> switch ($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">"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;";
+</font> break;</font>
+ default:
+ die('<font color="#993300">Unsupported feature</font>');
+ }
+<font color="#000000"><font color="green"> # @RETVAL = SP_RUNSOMETHING @myid,@group</font>
+ $stmt = $db->PrepareSP($sql); <br> $db->Parameter($stmt,$id,'<font color="#993300">myid</font>');
+ $db->Parameter($stmt,$group,'<font color="#993300">group</font>');
+ <font color="green"># true indicates output parameter<br> </font>$db->Parameter($stmt,$ret,'<font color="#993300">RETVAL</font>',true);
+ $db->Execute($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 = "<font color="#993300">SELECT * FROM articles WHERE match (title,body) against (%s</font>)";</pre>
+<p>In our main PHP file:</p>
+<pre><font color=green># define which database to load...</font>
+<b>$database = '<font color="#993300">mysql</font>';
+include_once("<font color="#993300">$database-lang.inc.php</font>");</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 = $db->Execute(sprintf($sqlSearchKeyWord,$db->qstr($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.

-<pre> You say eether and I say eyether, \r
- You say neether and I say nyther; \r
- Eether, eyether, neether, nyther - \r
- Let's call the whole thing off ! \r
-<br>\r
- You like potato and I like po-tah-to, \r
- You like tomato and I like to-mah-to; \r
- Potato, po-tah-to, tomato, to-mah-to - \r
- Let's call the whole thing off ! \r
-</pre>\r
-<p>I love this song, especially the version with Louis Armstrong and Ella singing \r
- duet. It is all about how hard it is for two people in love to be compatible \r
- with each other. It's about compromise and finding a common ground, and that's \r
- what this article is all about. \r
-<p>PHP is all about creating dynamic web-sites with the least fuss and the most \r
- fun. To create these websites we need to use databases to retrieve login information, \r
- to splash dynamic news onto the web page and store forum postings. So let's \r
- say we were using the popular MySQL database for this. Your company has done \r
- such a fantastic job that the Web site is more popular than your wildest dreams. \r
- You find that MySQL cannot scale to handle the workload; time to switch databases. \r
-<p> Unfortunately in PHP every database is accessed slightly differently. To connect \r
- to MySQL, you would use <i>mysql_connect()</i>; when you decide to upgrade to \r
- Oracle or Microsoft SQL Server, you would use <i>ocilogon() </i>or <i>mssql_connect()</i> \r
- respectively. What is worse is that the parameters you use for the different \r
- connect functions are different also.. One database says po-tato, the other \r
- database says pota-to. Oh-oh. \r
-<h3>Let's NOT call the whole thing off</h3>\r
-<p>A database wrapper library such as ADODB comes in handy when you need to ensure portability. It provides \r
- you with a common API to communicate with any supported database so you don't have to call things off. <p>\r
-\r
-<p>ADODB stands for Active Data Objects DataBase (sorry computer guys are sometimes \r
- not very original). ADODB currently supports MySQL, PostgreSQL, Oracle, Interbase, \r
- Microsoft SQL Server, Access, FoxPro, Sybase, ODBC and ADO. You can download \r
- ADODB from <a href=http://php.weblogs.com/adodb></a><a href="http://php.weblogs.com/adodb">http://php.weblogs.com/adodb</a>.\r
-<h3>MySQL Example</h3>\r
-<p>The most common database used with PHP is MySQL, so I guess you should be familiar \r
- with the following code. It connects to a MySQL server at <i>localhost</i>, \r
- database <i>mydb</i>, and executes an SQL select statement. The results are \r
- printed, one line per row. \r
-<pre><font color="#666600">$db = <b>mysql_connect</b>("localhost", "root", "password");\r
-<b>mysql_select_db</b>("mydb",$db);</font>\r
-<font color="#660000">$result = <b>mysql_query</b>("SELECT * FROM employees",$db)</font><code><font color="#663300">;\r
-if ($result === false) die("failed");</font></code> \r
-<font color="#006666"><b>while</b> ($fields =<b> mysql_fetch_row</b>($result)) {\r
- <b>for</b> ($i=0, $max=sizeof($fields); $i < $max; $i++) {\r
- <b>print</b> $fields[$i].' ';\r
- }\r
- <b>print</b> "<br>\n";\r
-}</font> \r
-</pre>\r
-<p>The above code has been color-coded by section. The first section is the connection \r
- phase. The second is the execution of the SQL, and the last section is displaying \r
- the fields. The <i>while</i> loop scans the rows of the result, while the <i>for</i> \r
- loop scans the fields in one row.</p>\r
-<p>Here is the equivalent code in ADODB</p>\r
-<pre><b><font color="#666600"> include("adodb.inc.php");</font></b><font color="#666600">\r
- $db = <b>NewADOConnection</b>('mysql');\r
- $db-><b>Connect</b>("localhost", "root", "password", "mydb");</font>\r
- <font color="#663300">$result = $db-><b>Execute</b>("SELECT * FROM employees");\r
- </font><font color="#663300"></font><code><font color="#663300">if ($result === false) die("failed")</font></code><code><font color="#663300">;</font></code> \r
- <font color="#006666"><b>while</b> (!$result->EOF) {\r
- <b>for</b> ($i=0, $max=$result-><b>FieldCount</b>(); $i < $max; $i++)\r
- <b>print</b> $result->fields[$i].' ';\r
- $result-><b>MoveNext</b>();\r
- <b>print</b> "<br>\n";\r
- }</font> </pre>\r
-<p></p>\r
-<p>Now porting to Oracle is as simple as changing the second line to <code>NewADOConnection('oracle')</code>. \r
- Let's walk through the code...</p>\r
-<h3>Connecting to the Database</h3>\r
-<p></p>\r
-<pre><b><font color="#666600">include("adodb.inc.php");</font></b><font color="#666600">\r
-$db = <b>NewADOConnection</b>('mysql');\r
-$db-><b>Connect</b>("localhost", "root", "password", "mydb");</font></pre>\r
-<p>The connection code is a bit more sophisticated than MySQL's because our needs \r
- are more sophisticated. In ADODB, we use an object-oriented approach to managing \r
- the complexity of handling multiple databases. We have different classes to \r
- handle different databases. If you aren't familiar with object-oriented programing, \r
- don't worry -- the complexity is all hidden away in the<code> NewADOConnection()</code> \r
- function.</p>\r
-<p>To conserve memory, we only load the PHP code specific to the database you \r
- are connecting to. We do this by calling <code>NewADOConnection(databasedriver)</code>. \r
- Legal database drivers include <i>mysql, mssql, oracle, oci8, postgres, sybase, \r
- vfp, access, ibase </i>and many others.</p>\r
-<p>Then we create a new instance of the connection class by calling <code>NewADOConnection()</code>. \r
- Finally we connect to the database using <code>$db->Connect(). </code></p>\r
-<h3>Executing the SQL</h3>\r
-<p><code><font color="#663300">$result = $db-><b>Execute</b>("SELECT * \r
- FROM employees");<br>\r
- if ($result === false) die("failed")</font></code><code><font color="#663300">;</font></code> \r
- <br>\r
-</p>\r
-<p>Sending the SQL statement to the server is straight forward. Execute() will \r
- return a recordset object on successful execution. You should check $result \r
- as we do above.\r
-<p>An issue that confuses beginners is the fact that we have two types of objects \r
- in ADODB, the connection object and the recordset object. When do we use each?\r
-<p>The connection object ($db) is responsible for connecting to the database, \r
- formatting your SQL and querying the database server. The recordset object ($result) \r
- is responsible for retrieving the results and formatting the reply as text or \r
- as an array.\r
-<p>The only thing I need to add is that ADODB provides several helper functions \r
- for making INSERT and UPDATE statements easier, which we will cover in the Advanced \r
- section. \r
-<h3>Retrieving the Data<br>\r
-</h3>\r
-<pre><font color="#006666"><b>while</b> (!$result->EOF) {\r
- <b>for</b> ($i=0, $max=$result-><b>FieldCount</b>(); $i < $max; $i++)\r
- <b>print</b> $result->fields[$i].' ';\r
- $result-><b>MoveNext</b>();\r
- <b>print</b> "<br>\n";\r
-}</font></pre>\r
-<p>The paradigm for getting the data is that it's like reading a file. For every \r
- line, we check first whether we have reached the end-of-file (EOF). While not \r
- end-of-file, loop through each field in the row. Then move to the next line \r
- (MoveNext) and repeat. \r
-<p>The <code>$result->fields[]</code> array is generated by the PHP database \r
- extension. Some database extensions do not index the array by field name. \r
- To force indexing by name - that is associative arrays - \r
- use the $ADODB_FETCH_MODE global variable. \r
-<pre>\r
- $<b>ADODB_FETCH_MODE</b> = ADODB_FETCH_NUM;\r
- $rs1 = $db->Execute('select * from table');\r
- $<b>ADODB_FETCH_MODE</b> = ADODB_FETCH_ASSOC;\r
- $rs2 = $db->Execute('select * from table');\r
- print_r($rs1->fields); // shows <i>array([0]=>'v0',[1] =>'v1')</i>\r
- print_r($rs2->fields); // shows <i>array(['col1']=>'v0',['col2'] =>'v1')</i>\r
-</pre>\r
-<p>\r
-As you can see in the above example, both recordsets store and use different fetch modes\r
-based on the $ADODB_FETCH_MODE setting when the recordset was created by Execute().</p>\r
-<h2>ADOConnection<a name="ADOConnection"></a></h2>\r
-<p>Object that performs the connection to the database, executes SQL statements \r
- and has a set of utility functions for standardising the format of SQL statements \r
- for issues such as concatenation and date formats.</p>\r
- \r
-<h3>Other Useful Functions</h3>\r
-<p><code>$recordset->Move($pos)</code> scrolls to that particular row. ADODB supports forward \r
- scrolling for all databases. Some databases will not support backwards scrolling. \r
- This is normally not a problem as you can always cache records to simulate backwards \r
- scrolling. \r
-<p><code>$recordset->RecordCount()</code> returns the number of records accessed by the \r
- SQL statement. Some databases will return -1 because it is not supported. \r
-<p><code>$recordset->GetArray()</code> returns the result as an array. \r
-<p><code>rs2html($recordset)</code> is a function that is generates a HTML table based on the \r
- $recordset passed to it. An example with the relevant lines in bold:\r
-<pre> include('adodb.inc.php'); \r
- <b>include('tohtml.inc.php');</b> /* includes the rs2html function */\r
- $conn = &ADONewConnection('mysql'); \r
- $conn->PConnect('localhost','userid','password','database');\r
- $rs = $conn->Execute('select * from table');\r
- <b> rs2html($rs)</b>; /* recordset to html table */ </pre>\r
-<p>There are many other helper functions that are listed in the documentation available at <a href="http://php.weblogs.com/adodb_manual"></a><a href="http://php.weblogs.com/adodb_manual">http://php.weblogs.com/adodb_manual</a>. \r
-<h2>Advanced Material</h2>\r
-<h3>Inserts and Updates </h3>\r
-<p>Let's say you want to insert the following data into a database. \r
-<p><b>ID</b> = 3<br>\r
- <b>TheDate</b>=mktime(0,0,0,8,31,2001) /* 31st August 2001 */<br>\r
- <b>Note</b>= sugar why don't we call it off \r
-<p>When you move to another database, your insert might no longer work.</p>\r
-<p>The first problem is that each database has a different default date format. \r
- MySQL expects YYYY-MM-DD format, while other databases have different defaults. \r
- ADODB has a function called DBDate() that addresses this issue by converting \r
- converting the date to the correct format.</p>\r
-<p>The next problem is that the <b>don't</b> in the Note needs to be quoted. In \r
- MySQL, we use <b>don\'t</b> but in some other databases (Sybase, Access, Microsoft \r
- SQL Server) we use <b>don''t. </b>The qstr() function addresses this issue.</p>\r
-<p>So how do we use the functions? Like this:</p>\r
-<pre>$sql = "INSERT INTO table (id, thedate,note) values (" \r
- . $<b>ID</b> . ','\r
- . $db->DBDate($<b>TheDate</b>) .','\r
- . $db->qstr($<b>Note</b>).")";\r
-$db->Execute($sql);</pre>\r
-<p>ADODB also supports <code>$connection->Affected_Rows()</code> (returns the \r
- number of rows affected by last update or delete) and <code>$recordset->Insert_ID()</code> \r
- (returns last autoincrement number generated by an insert statement). Be forewarned \r
- that not all databases support the two functions.<br>\r
-</p>\r
-<h3>MetaTypes</h3>\r
-<p>You can find out more information about each of the fields (I use the words \r
- fields and columns interchangebly) you are selecting by calling the recordset \r
- method <code>FetchField($fieldoffset)</code>. This will return an object with \r
- 3 properties: name, type and max_length. \r
-<pre>For example:</pre>\r
-<pre>$recordset = $conn->Execute("select adate from table");<br>$f0 = $recordset->FetchField(0);\r
-</pre>\r
-<p>Then <code>$f0->name</code> will hold <i>'adata'</i>, <code>$f0->type</code> \r
- will be set to '<i>date'</i>. If the max_length is unknown, it will be set to \r
- -1. \r
-<p>One problem with handling different databases is that each database often calls \r
- the same type by a different name. For example a <i>timestamp</i> type is called \r
- <i>datetime</i> in one database and <i>time</i> in another. So ADODB has a special \r
- <code>MetaType($type, $max_length)</code> function that standardises the types \r
- to the following: \r
-<p>C: character and varchar types<br>\r
- X: text or long character (eg. more than 255 bytes wide).<br>\r
- B: blob or binary image<br>\r
- D: date<br>\r
- T: timestamp<br>\r
- L: logical (boolean)<br>\r
- I: integer<br>\r
- N: numeric (float, double, money) \r
-<p>In the above date example, \r
-<p><code>$recordset = $conn->Execute("select adate from table");<br>\r
- $f0 = $recordset->FetchField(0);<br>\r
- $type = $recordset->MetaType($f0->type, $f0->max_length);<br>\r
- print $type; /* should print 'D'</code> */\r
-<p> \r
-<p><b>Select Limit and Top Support</b> \r
-<p>ADODB has a function called $connection->SelectLimit($sql,$nrows,$offset) that allows\r
-you to retrieve a subset of the recordset. This will take advantage of native\r
-SELECT TOP on Microsoft products and SELECT ... LIMIT with PostgreSQL and MySQL, and\r
-emulated if the database does not support it.\r
-<p><b>Caching Support</b> \r
-<p>ADODB allows you to cache recordsets in your file system, and only requery the database\r
-server after a certain timeout period with $connection->CacheExecute($secs2cache,$sql) and \r
-$connection->CacheSelectLimit($secs2cache,$sql,$nrows,$offset).\r
-<p><b>PHP4 Session Handler Support</b> \r
-<p>ADODB also supports PHP4 session handlers. You can store your session variables \r
- in a database for true scalability using ADODB. For further information, visit \r
- <a href="http://php.weblogs.com/adodb-sessions"></a><a href="http://php.weblogs.com/adodb-sessions">http://php.weblogs.com/adodb-sessions</a>\r
-<h3>Commercial Use Encouraged</h3>\r
-<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>\r

+
+<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><a href="http://php.weblogs.com/adodb">http://php.weblogs.com/adodb</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">$db = <b>mysql_connect</b>("localhost", "root", "password");
+<b>mysql_select_db</b>("mydb",$db);</font>
+<font color="#660000">$result = <b>mysql_query</b>("SELECT * FROM employees",$db)</font><code><font color="#663300">;
+if ($result === false) die("failed");</font></code>
+<font color="#006666"><b>while</b> ($fields =<b> mysql_fetch_row</b>($result)) {
+ <b>for</b> ($i=0, $max=sizeof($fields); $i < $max; $i++) {
+ <b>print</b> $fields[$i].' ';
+ }
+ <b>print</b> "<br>\n";
+}</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>
+<pre><b><font color="#666600"> include("adodb.inc.php");</font></b><font color="#666600">
+ $db = <b>NewADOConnection</b>('mysql');
+ $db-><b>Connect</b>("localhost", "root", "password", "mydb");</font>
+ <font color="#663300">$result = $db-><b>Execute</b>("SELECT * FROM employees");
+ </font><font color="#663300"></font><code><font color="#663300">if ($result === false) die("failed")</font></code><code><font color="#663300">;</font></code>
+ <font color="#006666"><b>while</b> (!$result->EOF) {
+ <b>for</b> ($i=0, $max=$result-><b>FieldCount</b>(); $i < $max; $i++)
+ <b>print</b> $result->fields[$i].' ';
+ $result-><b>MoveNext</b>();
+ <b>print</b> "<br>\n";
+ }</font> </pre>
+<p></p>
+<p>Now porting to Oracle is as simple as changing the second line to <code>NewADOConnection('oracle')</code>.
+ Let's walk through the code...</p>
+<h3>Connecting to the Database</h3>
+<p></p>
+<pre><b><font color="#666600">include("adodb.inc.php");</font></b><font color="#666600">
+$db = <b>NewADOConnection</b>('mysql');
+$db-><b>Connect</b>("localhost", "root", "password", "mydb");</font></pre>
+<p>The connection code is a bit more sophisticated than MySQL's because our needs
+ are more sophisticated. In ADODB, we use an object-oriented approach to managing
+ the complexity of handling multiple databases. We have different classes to
+ handle different databases. If you aren't familiar with object-oriented programing,
+ don't worry -- the complexity is all hidden away in the<code> NewADOConnection()</code>
+ function.</p>
+<p>To conserve memory, we only load the PHP code specific to the database you
+ are connecting to. We do this by calling <code>NewADOConnection(databasedriver)</code>.
+ Legal database drivers include <i>mysql, mssql, oracle, oci8, postgres, sybase,
+ vfp, access, ibase </i>and many others.</p>
+<p>Then we create a new instance of the connection class by calling <code>NewADOConnection()</code>.
+ Finally we connect to the database using <code>$db->Connect(). </code></p>
+<h3>Executing the SQL</h3>
+<p><code><font color="#663300">$result = $db-><b>Execute</b>("SELECT *
+ FROM employees");<br>
+ if ($result === false) die("failed")</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->EOF) {
+ <b>for</b> ($i=0, $max=$result-><b>FieldCount</b>(); $i < $max; $i++)
+ <b>print</b> $result->fields[$i].' ';
+ $result-><b>MoveNext</b>();
+ <b>print</b> "<br>\n";
+}</font></pre>
+<p>The paradigm for getting the data is that it's like reading a file. For every
+ line, we check first whether we have reached the end-of-file (EOF). While not
+ end-of-file, loop through each field in the row. Then move to the next line
+ (MoveNext) and repeat.
+<p>The <code>$result->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->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->RecordCount()</code> returns the number of records accessed by the
+ SQL statement. Some databases will return -1 because it is not supported.
+<p><code>$recordset->GetArray()</code> returns the result as an array.
+<p><code>rs2html($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 = &ADONewConnection('mysql');
+ $conn->PConnect('localhost','userid','password','database');
+ $rs = $conn->Execute('select * from table');
+ <b> rs2html($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><a href="http://php.weblogs.com/adodb_manual">http://php.weblogs.com/adodb_manual</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 = "INSERT INTO table (id, thedate,note) values ("
+ . $<b>ID</b> . ','
+ . $db->DBDate($<b>TheDate</b>) .','
+ . $db->qstr($<b>Note</b>).")";
+$db->Execute($sql);</pre>
+<p>ADODB also supports <code>$connection->Affected_Rows()</code> (returns the
+ number of rows affected by last update or delete) and <code>$recordset->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 = $conn->Execute("select adate from table");<br>$f0 = $recordset->FetchField(0);
+</pre>
+<p>Then <code>$f0->name</code> will hold <i>'adata'</i>, <code>$f0->type</code>
+ will be set to '<i>date'</i>. If the max_length is unknown, it will be set to
+ -1.
+<p>One problem with handling different databases is that each database often calls
+ the same type by a different name. For example a <i>timestamp</i> type is called
+ <i>datetime</i> in one database and <i>time</i> in another. So ADODB has a special
+ <code>MetaType($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->Execute("select adate from table");<br>
+ $f0 = $recordset->FetchField(0);<br>
+ $type = $recordset->MetaType($f0->type, $f0->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><a href="http://php.weblogs.com/adodb-sessions">http://php.weblogs.com/adodb-sessions</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>
