note 19779 added to function.mysql-num-rows

RE: Why does mysql_num_rows($query) in Control Structures returns "Warning: Supplied argument is not a valid MySQL result resource in ..." ? by html_addict@hotmail.com 30-Jan-2002 11:43 and Manuel_Hegemann@web.de 08-Feb-2002 07:49 I encountered the same problem and found that the "Warning" occures when no row was returned NOT by reason of "Empty set" BUT by reason of SQL error. Just try typing the query in MySQL prompt, then you will get an error. -- http://www.php.net/manual/en/function.mysql-num-rows.php http://master.php.net/manage/user-notes.php?action=edit+19779 http://master.php.net/manage/user-notes.php?action=delete+19779 http://master.php.net/manage/user-notes.php?action=reject+19779
