【问题描述】：

我正在导入一个存储过程，该过程刚刚从我的开发服务器导出到我的生产服务器中，我在 phymyadmin 中遇到了以下错误。

SQL query: Documentation

$$ CREATE DEFINER = `devuser`@`localhost` FUNCTION `get_refundable_amount` (
enrol_id INT
) RETURNS double( 10, 2 ) READS SQL DATA BEGIN DECLARE refundable_amount double( 10, 2 ) DEFAULT 0;

SELECT (
sum( P.amount ) - EI.amount
)
INTO refundable_amount
FROM site_payment_processed AS P
INNER JOIN site_user_enroled AS E ON ( P.enrol_id = E.id
AND P.payment_type = 'Refund' )
INNER JOIN site_user_enroled_invoice AS EI ON EI.enrol_id = E.id
WHERE E.id = enrol_id
GROUP BY E.id;

RETURN (
refundable_amount
);

END$$

MySQL said: Documentation
#1064 - 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 '$

CREATE DEFINER=`devuser`@`localhost` FUNCTION `get_refundable_amount`' at line 1

【解决方案1】：

用新定义的分隔符包围存储过程代码的主体（例如，从 ; 到 $$）。

DELIMITER $$
CREATE DEFINER = `devuser`@`localhost` FUNCTION `get_refundable_amount` (
enrol_id INT
) RETURNS double( 10, 2 ) READS SQL DATA BEGIN DECLARE refundable_amount double( 10, 2 ) DEFAULT 0;

SELECT (
sum( P.amount ) - EI.amount
)
INTO refundable_amount
FROM site_payment_processed AS P
INNER JOIN site_user_enroled AS E ON ( P.enrol_id = E.id
AND P.payment_type = 'Refund' )
INNER JOIN site_user_enroled_invoice AS EI ON EI.enrol_id = E.id
WHERE E.id = enrol_id
GROUP BY E.id;

RETURN (
refundable_amount
);

END $$
DELIMITER ;

【解决方案2】：

Creating functions in mysql doesnt work - Error 1064 中提出的解决方案完全足够了。

问题在于 phpMyAdmin。从 mysql 命令行运行效果很好。
