MySQL存储函数创建错误ERROR 1064和1327

我正在使用MySQL v5.1.36,我正在尝试使用此代码创建存储函数.

DELIMITER //
CREATE FUNCTION `modx`.getSTID (x VARCHAR(255)) RETURNS INT DETERMINISTIC
    BEGIN
    DECLARE y INT;
    SELECT id INTO y
    FROM `modx`.coverage_state
    WHERE `coverage_state`.name = x;
    RETURN y;
    END//

当进入MySQL控制台时,我得到了这个回复.

mysql>  DELIMITER //
mysql>  CREATE FUNCTION `modx`.getSTID (x VARCHAR(255)) RETURNS INT DETERMINISTIC
    ->          BEGIN
    ->          DECLARE y INT;
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 '' at
line 3
mysql>          SELECT id INTO y
    ->          FROM `modx`.coverage_state
    ->          WHERE `coverage_state`.name = x;
ERROR 1327 (42000): Undeclared variable: y
mysql>          RETURN y;
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 'RETUR
N y' at line 1
mysql>          END//

从我在网上找到的我的语法是正确的.我究竟做错了什么？ 最佳答案 从mysql控制台创建函数/过程时,第一个命令应该是DELIMITER //.否则,它使用默认分隔符(;),
