SQL LIMIT clauses aren't cross-db so they must be replaced by function calls using the new limitfrom and limitnum parameters. Current uses are:

admin/report/courseoverview/reportsgraph.php: $sql = $param->sql ." LIMIT ".$numcourses;
admin/report/courseoverview/reportsgraph.php: ." LIMIT ".$numcourses;

blocks/blog_tags/block_blog_tags.php: $sql .= "LIMIT {$this->config->numberoftags} ";

blocks/search_glossaries/search_glossaries.php: $sqllimit = " LIMIT $entriesbypage OFFSET $offset";
blocks/search_glossaries/search_glossaries.php: $sqllimit = " LIMIT $offset, $entriesbypage";

blog/lib.php: //echo 'Debug: BlogFilter fetch_entries() sql="'. $SQL . $orderby . $limit .'"<br />'. $this->categoryid; //debug

lib/datalib.php: $limit = sql_paging_limit($limitfrom, $limitnum);
lib/datalib.php: $limit = "";

lib/dmllib.php: return 'LIMIT '. $recordsperpage .' OFFSET '. $page;
lib/dmllib.php: return 'LIMIT '. $page .','. $recordsperpage;

mod/chat/lib.php: ORDER BY timestamp DESC LIMIT 1")) {

mod/data/rsslib.php: "LIMIT {$data->rssarticles}";

mod/glossary/sql.php: $sqllimit = " LIMIT $entriesbypage OFFSET $offset";
mod/glossary/sql.php: $sqllimit = " LIMIT $offset, $entriesbypage";

mod/quiz/report/analysis/report.php: $scorelimit = $quiz->sumgrades * $lowmarklimit/ 100;
mod/quiz/report/analysis/report.php: $limit = '';
mod/quiz/report/analysis/report.php: $limit = ', max(qa.sumgrades) ';
mod/quiz/report/analysis/report.php: $limit = ', min(qa.timemodified) ';
mod/quiz/report/analysis/report.php: $limit = ', max(qa.timemodified) ';

mod/wiki/ewiki/ewiki.php: . " WHERE (pagename=$id) $version ORDER BY version DESC LIMIT 1"
mod/wiki/ewikimoodlelib.php: # . " WHERE (pagename=$id) $version ORDER BY version DESC LIMIT 1"
