------解决方案--------------------
没试你的语句没有任何错误啊。

SQL code

mysql> delimiter //
mysql> CREATE PROCEDURE dowhile()
    -> BEGIN
    ->  DECLARE v1 INT DEFAULT 5;
    ->  WHILE v1 > 0 DO
    ->    SET v1 = v1 - 1;
    ->  END WHILE;
    -> END
    -> //
Query OK, 0 rows affected (0.44 sec)

mysql> delimiter ;
mysql>
mysql> call dowhile;
Query OK, 0 rows affected (0.00 sec)
