note 24990 added to function.mysql-info

This function can be used as a workaround for a misfeature of MySQL: on an UPDATE, rows that aren't updated _solely because they looked the same before_ will not be seen in mysql_affected_rows(). This causes problems when you want to use the result of the update to determine if there's need to do an INSERT. With MySQL you can do an INSERT IGNORE if there's no risk of if failing because of a duplicate key other than the one used in the UPDATE. However, if this isn't the case or you want a bit of RDBMS independence, there's no easy/pretty workaround. I think I'll resort to doing a SELECT to determine the primary key before doing the update/insert, as using the CVS version of PHP isn't an option for me. -- http://www.php.net/manual/en/function.mysql-info.php http://master.php.net/manage/user-notes.php?action=edit+24990 http://master.php.net/manage/user-notes.php?action=delete+24990 http://master.php.net/manage/user-notes.php?action=reject+24990
