This query takes 206 seconds: SELECT t1.blah, t1.foo, t2.id FROM t1, t2, t3 WHERE t1.SessionId = 427 AND t1.CatalogId = 22 AND t1.CatalogId = t3.CatalogId AND t2.id = t3.SomeId AND t2.Active != 0 If I change the last line to this, it takes 1 second: AND t2.Active = 1 The "Active" field is 0 or 1. The query returns the same rows, either way (about 1700 rows). There is an index on the Active field. These two queries both take 1 second: SELECT * FROM t2 WHERE Active = 1; SELECT * FROM t2 WHERE Active != 0; Any ideas?
