Check the manual that corresponds to your MySQL server version for the right syntax to use near ';DELETE FROM orders WHERE table_name = "zorder_47629403705b7e7f Here is my script... $sql = 'SELECT table_name FROM orders WHERE completed = "0000-00-00 00:00:00"'; $objRecordSet = new RecordSet($sql); $sql = ''; while ($rows = mysql_fetch_array($objRecordSet->getResultID())) { //$sql .= ' DROP TABLE xxx.'.$rows['table_name'].';DELETE FROM orders WHERE table_name = "'.$rows['table_name'].'";'; } $dbConn = mysql_connect("localhost", "root", "new-password"); mysql_select_db("xxx", $dbConn); mysql_query($sql, $dbConn); echo "<br>".mysql_error(); Any ideas
