Like Fred said, UNION if you use 4.x, but if you use 3.23.x, you could use the MERGE tables option: <URL: http://www.mysql.com/doc/en/MERGE.html > You basically create a 'wrapper' table around your existing two (or more) identically strucured tables, and can query them all in a single SELECT like if it was a single table. -- Roger -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
