mysql - 检查 mySQL 是否正确

Question

PHPmyAdmin 一直拒绝这个 mySQL，我很确定它是正确的，实际上并不需要它运行，它的 uni 工作并且只需要提交，它看起来对我来说是正确的。

我得到的实际错误是

#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 'END' at line 23 

我尝试过添加和删除；要 LIMIT 和 END 哪一个帮助，我是不是很愚蠢？

CREATE PROCEDURE topFive(
   IN PID VARCHAR(6),
   IN CID VARCHAR(6)
)
BEGIN

SELECT `OrderItem`.`ProductID` , COUNT(*) AS `Popularity`
FROM `OrderItem`,
(
SELECT `Order`.`OrderID`
FROM `OrderItem`,`Order`
WHERE
(`Order`.`OrderID`=`OrderItem`.`OrderID`)
AND 
(`OrderItem`.`ProductID`=PID)
AND
(`Order`.`CustomerID`!=CID)
) AS `ORDER_ID_TABLE`
WHERE  (`OrderItem`.`OrderID` = `ORDER_ID_TABLE`.`OrderID`)
GROUP BY `OrderItem`.`ProductID`
ORDER BY `Popularity`
LIMIT 0,5

END

谢谢^_^

Answer 1

您必须更改分隔符。至少在 MySQL 客户端中，您可以这样做：

DELIMITER //

CREATE PROCEDURE topFive(
   IN PID VARCHAR(6),
   IN CID VARCHAR(6)
)
BEGIN

SELECT `OrderItem`.`ProductID` , COUNT(*) AS `Popularity`
FROM `OrderItem`,
(
SELECT `Order`.`OrderID`
FROM `OrderItem`,`Order`
WHERE
(`Order`.`OrderID`=`OrderItem`.`OrderID`)
AND 
(`OrderItem`.`ProductID`=PID)
AND
(`Order`.`CustomerID`!=CID)
) AS `ORDER_ID_TABLE`
WHERE  (`OrderItem`.`OrderID` = `ORDER_ID_TABLE`.`OrderID`)
GROUP BY `OrderItem`.`ProductID`
ORDER BY `Popularity`
LIMIT 0,5//

END
