Do you have separate indexes on: Table1.ID Table2.ID Table1.Field1 Table2.Field1 Table1.Field1 Table1.Field2
> Select * > FROM Table1 as a > INNER JOIN Table2 as b ON (a.ID = b.ID or (a.Field1 = b.Field1 and > a.Field2 = b.Field2)) > WHERE bla bla bla > > We have tried to set up indexes and the query still takes 8 minutes to > run. It only returns 6,000 records. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
