MySQL5.0存储过程语法

我只是在尝试创建我的第一个MySQL存储过程,并尝试直接从文档中复制一些示例,但它不起作用:

mysql> delimiter //
mysql> CREATE PROCEDURE ghost.test (OUT param1 INT) INSERT into admins SELECT COUNT(*) FROM bans; END//
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '; END' at line 1

这里有什么交易?这几乎等同于:

mysql> delimiter //

mysql> CREATE PROCEDURE simpleproc (OUT param1 INT)
    -> BEGIN
    ->   SELECT COUNT(*) INTO param1 FROM t;
    -> END//
Query OK, 0 rows affected (0.00 sec)
