Query Question

I have the following table A, together the 2 columns make a key:

Then I have table B which is a subset of table A same columns.

How can I get the values which are in table A which are not in table B?  I need all the card/profile combinations in A which are not in B.

I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

try this
SELECT tableA.* FROM tableA LEFT JOIN tableB ON (tableA.CardNumber=tableB.CardNumber AND tableA.Profile=tableB.Profile) WHERE
(tableB.CardNumber IS NULL OR tableB.Profile IS NULL)

This is more simpler using EXCEPT command which eliminates records from the second query.

(SELECT     CardNumber, Profile
FROM         TableA)
(SELECT     CardNumber, Profile
FROM         Table2)
