note 42517 added to function.mysql-affected-rows

Just a MySQL note, using REPLACE INTO on a record could return either ONE or TWO affected rows with this function. Basically, REPLACE INTO will insert a record if no combination of unique keys is matched, or delete the existing record if the new record matches one or more unique keys, then insert the new record over it. This is actually helpful if you want to know if a record was already in there. (Affected rows=1 means there wasn't already a record there, Affected rows=2 means there was), but if you don't know how REPLACE INTO works it could confuse you. I didn't see this in the notes above and hope it helps someone out. ---- Manual Page -- http://www.php.net/manual/en/function.mysql-affected-rows.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+42517 Delete -- http://master.php.net/manage/user-notes.php?action=delete+42517&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+42517&report=yes Search -- http://master.php.net/manage/user-notes.php
