That can happen and it is fine.

If you add a single column dummy key, you would still have to have uniqueness constraints on the present keys, then you would have to validate the dummy key against the natural key. You will probably get faster joins, but the database will get corrupted. Received on Wed Sep 26 2001 - 23:54:59 CEST
