How many records are in each table?
It could take a while, especially if you don't have indexes on the join
fields.

Hi Neil,
what you need is a LEFT JOIN:
SELECT a.*
FROM TableA a
LEFT JOIN TableB b ON a.ID = b.ID (assuming ID is what you relate the
tables on )
WHERE b.ID IS NULL;
should hopefully do what you want.
