Look at the functions HOUR(time), MINUTE(time), SECOND(time). These will give you interger output for each part of the time field. Also TIME_TO_SEC(time) may be useful for you. I believe that all of these are supported in 3.23. If your times aren't greater than 838:59:59 this should work for you. -- Tom Crimmins Interface Specialist Pottawattamie County, Iowa -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
