>Hi Courtney,
If the USAGE table has already been created then you can issue an INSERT:

INSERT INTO Usage(caid,pairs)
SELECT caid,pairs
FROM RetardedUsage
WHERE caid=20 and

             pairs < 600;

>You could have done the whole thing at the time you created the new table by
Issuing;
CREATE TABLE Usage AS
SELECT caid, pairs
FROM RetardedUsage
WHERE caid=20 and

             pairs<600;
