I'm a SQL newbie so please bare with me. I have two tables that I want to
query against and determine what records exist in the first that don't exist
in the second and vice versa. I'm wondering what is the most efficient means
to find and add the records that exist in the first table but not in the
second table to the second table. Also, I want to delete any records that
exist in the second table but don't exist in the first from the second table
(sorry, not a very clear description, I know). Any advise would be greatly
appreciated.
