MySQL 创建存储过程时出错

Question

我想创建一个存储过程来处理来自我们网站的订单。问题是当我运行脚本时出现 MySQL 语法错误。我对 MySQL 存储过程很陌生。有人可以看看我的代码吗？

USE postbrood;
DELIMITER //
CREATE PROCEDURE MaakBestelling(IN KlantIDParam INT, IN ProductIDArray VARCHAR(255), IN AantalArray VARCHAR(255))

BEGIN
DECLARE BestelID INT DEFAULT 0;
DECLARE ArrayLenght INT DEFAULT 0;
DECLARE Counter INT DEFAULT 0;



SET ArrayLenght = LENGTH(ProductIDArray) - LENGTH(REPLACE(ProductIDArray, ',', '')) + 1;


INSERT INTO bestelling(klantID) VALUES (KlantIDParam);
SET BestelID = LAST_INSERT_ID();

WHILE Counter < ArrayLenght DO
INSERT INTO bestelregel VALUES (SUBSTRING_INDEX(ProductIDArray,',',Counter),BestelID,SUBSTRING_INDEX(AantalArray,',',Counter));
SET Counter = Counter + 1;
END WHILE;
END//
DELIMITER ;

提前致谢！

Answer 1

我认为

中的逗号未被识别

SET ArrayLenght = LENGTH(ProductIDArray) - LENGTH(REPLACE(ProductIDArray, ',', '')) + 1;

您应该尝试用 ascii 实体编号替换逗号：,

Answer 2

搞定了！ :)

USE postbrood;
DELIMITER //
CREATE PROCEDURE MaakBestelling(IN KlantIDParam INT, IN ProductIDArray VARCHAR(255), IN AantalArray VARCHAR(255))

BEGIN
DECLARE BestelID INT DEFAULT 0;
DECLARE ArrayLenght INT DEFAULT 0;
DECLARE Counter INT DEFAULT 0;



SET ArrayLenght = LENGTH(ProductIDArray) - LENGTH(REPLACE(ProductIDArray, ',', '')) + 1;


INSERT INTO bestelling(klantID) VALUES (KlantIDParam);
SET BestelID = LAST_INSERT_ID();

WHILE Counter < ArrayLenght DO
INSERT INTO bestelregel VALUES (SUBSTRING_INDEX(ProductIDArray,',',Counter),BestelID,SUBSTRING_INDEX(AantalArray,',',Counter),2.50);
SET Counter = Counter + 1;
END WHILE;
END//
DELIMITER ;
