Not really. You could do something like foreach ( array('team', 'conflicts', 'home_field') as $table ) { $result = mysql_query("DELETE FROM $table WHERE team_id = '$team_id'"); } but that's the same as far as MySQL is concerned. > I tried > $result=mysql_query("DELETE FROM team,conflicts,home_field WHERE team_id = > '$team_id'"); > But of course, that doesn't work.

I'm pretty sure there's nothing resembling that that will work, I don't see what you think the advantage would be, and I don't understand what you mean about trying to delete from tables that don't have team_id (should MySQL magically know which records are associated with an ID that's not even in the table?). -- Keith C.
