Oracle:
INSERT INTO (SELECT department_id, department_name, location_id
FROM departments WHERE location_id < 2000 WITH CHECK OPTION)
VALUES (9999, 'Entertainment', 1500);
why have select statement for insert columns? and also that where clause
does not make a lot of sense to me...
can someone one tell me what it means and what is the purpose for this kind
of query?
Thanks!
