Yes, I would definitely use a different index. You need an index which has both columns. Try one of these. The second should be faster, but you are only allowed to have one clustered index per table. Use the clustered option on the index you use the most. Do one of these from mysql command line interface.

CREATE INDEX exp_update ON campaigns ( mw_export, last_update )
--or this 
CREATE clustered INDEX cl_exp_update ON campaigns ( mw_export, last_up
+date )

Thanks. I know that I should be using indexes and I was surprised that the ones I created didn't help out much.
