Page 303: Last line in query not necessary

On page 303, under "Correlated Subqueries", the last line in the example query is not necessary, and deleting the last line will not change the results of the query.

This example can also be written:

SELECT T.title_id, title
FROM titles T
WHERE PRICE <= 19.99
and T.title_id IN (
SELECT S.title_id FROM sales S, stores ST
WHERE S.stor_id=ST.stor_id
AND ST.state='CA' AND S.qty*T.price > 250
