我有一个要求,我必须使用三个 IN 参数和 6 个 OUT 参数调用 MySql 存储过程。
程序
DELIMITER $$
DROP PROCEDURE IF EXISTS GET_PRODUCT_INFO $$
CREATE PROCEDURE GET_PRODUCT_INFO(IN productName varchar(25),
IN divisionID int(11), IN productQuantity int(11),
OUT Price double, OUT price_without_vat double,
OUT vat double, OUT Quantity int, OUT ProductsId int, OUT ExpDate date)
BEGIN
select I.quantity into Quantity from ProductInventory I
where I.pname=productName and I.divid=divisionID ;
if Quantity > productQuantity THEN
select P.productID,P.price,P.price_without_vat,P.vat, I.quantity,P.ExpiryDate
into ProductsId,Price,price_without_vat,vat,Quantity,ExpDate
from product P,ProductInventory I
where P.pname=productName and I.pname=productName
and P.orgid=divisionID and I.divid=divisionID ;
update productinventory
set quantity=(quantity-productQuantity)
where pname=productName and divID=divisionID;
END IF;
END $$
call GET_PRODUCT_INFO('Crocin',1,2,@Price,@price_without_vat,@vat,@Quantity,@ProductsId,@ExpiryDate)$$
在这里,我可以在 mysql cmd 提示符中检索记录...但是每当我尝试从我的 JDBC 代码调用该过程时,都会收到此错误
例外
