Hello, I've tried your way, but my SQL reports error, that I have specified more than ONE primary key, so I can't do the primary key on both fields. Is that a mySQL 3.X limitation ? My tables are ISAM. Following your advice, I've deleted the relation_person_carID, so only cardID and personID are left i nthe table, with no primary key. Is it a good idea, and is it safe, not to have a primary key ?
