Is it OK to keep adding to those joins? In a view there could be say 50 countries. The user can keep on adding more to exclude. So would I just expand on the ANDs like so: AND map1.cc !='CA' AND map1.cc !='US' AND map1.cc !='LV'... ? -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/mysql?unsub=arch...@jab.org
