I'm pretty sure that just looks like a bunch of ORs to MySQL. If it didn't use the index with OR, it won't use it with IN. What usually works is to change it to UNION: SELECT wite_what, wite_desc FROM witelist WHERE wite_what = '$oct1' UNION SELECT wite_what, wite_desc FROM witelist WHERE wite_what = '$oct1.$oct2' UNION ...etc. - Perrin -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
