Sorry, brain was switched off when I wrote that. It should be: SELECT single_rooms+double_rooms+twin_rooms from TABLE; Or, if you want a boolean value depending if there are less than 10: SELECT IF((single_rooms+double_rooms+twin_rooms) < 10,1,0) from TABLE; Edward -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
