I used different datatypes which, of course, was the wrong test. When I update the values in t1 I need to ensure I only get data from t1 that has the new column NULL. Constraints to be checked are still only the ones attached to the altered table directly. A constraint on t1 only will not affect data on t2. -- Rod Taylor <[EMAIL PROTECTED]> PGP Key: http://www.rbt.ca/rbtpub.asc
