Of course you're right. Thanks. According to your suggestion this one works okey: SELECT @a FROM tCustomers WHERE @a:=FIRMLEGALZIPCODE REGEXP [0-9] -- ./ premax ./ [EMAIL PROTECTED] ./ koniec i bomba, a kto czytal ten traba. w.g. -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]

According to your suggestion this one works okey: SELECT @a FROM tCustomers WHERE @a:=FIRMLEGALZIPCODE REGEXP [0-9] True, although in this case you don't need a user variable at all: SELECT FIRMLEGALZIPCODE FROM tCustomers WHERE FIRMLEGALZIPCODE REGEXP [0-9] -- Paul DuBois, MySQL Documentation Team Madison, Wisconsin, USA MySQL AB, www.mysql.com -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe:http://lists.mysql.com/[EMAIL PROTECTED]
