If its so easy then why is your answer so *obviously* incorrect. I would normally do exactly what you said except for the fact table table B has a composite primary key composed of MyKey and UniqueKey and it relates to table A which has a composite foreign key of MyKey and UniqueKey. Not only that, your solution fails to use UniqueKey at all!! Received on Tue Aug 20 2002 - 17:31:34 CDT
