Subject: Applied DISTINCT as per Martin Langhoff's solution in MDL-11381
X-Git-Url: http://git.mjollnir.org/gw?a=commitdiff_plain;h=5f2a203fa0404985798c197ab192a2df632782df;p=moodle.git

Applied DISTINCT as per Martin Langhoff's solution in MDL-11381

user/index: ensure each user appears only once in participants list

Regardless of the number of enrolments, ensure we list a single entry
per user using DISTINCT. Much easier to manage than a GROUP BY.
