Why not go all the way...and squeeze EVERY LAST DROP of performance out = of this query?

TRUNCATE TABLE URL_PAGES drop storage;

I don't understand why some DBAs just don't "cross all the T's and dot = all the I's"

etc.

The following command will speed the query up tremendously:

TRUNCATE TABLE URL_PAGES; Executing this command will speed up the query for an order of = magnitude. You don't have to thank me. That is all I can help you with = without knowing the availability of indexes, distribution of data in the = indexed columns, size of the table and server version.
