通過創建存儲過程導致MySQL錯誤

Question

我想創建一個處理來自我們網站的訂單的存儲過程。問題是，當我運行腳本時出現MySQL語法錯誤。我對MySQL存儲過程很陌生。有人可以看我的代碼嗎？

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 ; 

在此先感謝！

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 ;

我覺得逗號不是在

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

被認可你應該嘗試與ascii實體號代替逗號：,
