Thank you for your response. While I rather dislike using hacks the above would probably work well enough for my purposes. Unfortunately I do most of my work in a version of MySQL <5.0 (3.23.49) so I don't have access to the index merge optimization so the above would only use one index for me, but that would probably be good enough. One more reason to try to get my sys admin to upgrade... -- Rob Wultsch [EMAIL PROTECTED] wultsch (aim) -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
