如何在SQL SERVER 2005存储过程中,使用循环语句

CREAT PROCEDURE tester  
AS
BEGIN
    SET NOCOUNT ON;
    DECLARE @userId varchar(50)
    DECLARE @count int
    SET @count = 0
    SELECT @count = count(*) FROM   UserService_User WHERE Account like '%111%'
   WHILE @count > 0
    BEGIN
        SELECT @userId = Id FROM   UserService_User WHERE Account like '%111%'
        exec UserService_RemoveUserByUserId @userId
        SET @count = @count -1
    END
END
