【问题描述】：

所以我用 MySQL 编写了这个程序，谁能告诉我为什么它不起作用？

create procedure add_Order(
    IN custid int,
    IN productid int,
    IN storeid int,
    IN  empid int,
    IN quantity int,
    IN R_payment char(10),
    IN date date)
begin
    insert into Orders(custid, empid, storeid, orderdate) values (IN_cust, IN_empid, IN_storeid, IN_date);
    insert into Order_Product(orderid, productid, quantity, RegisterPayment) values (IN_orderid, IN_productid, IN_quantity, IN_R_payment);
end

这是错误信息：

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 1

【问题讨论】：

您需要定义不同的分隔符才能使用。见mysql手册：dev.mysql.com/doc/connector-net/en/…
值字段名称需要对 in 参数名称进行数学运算。

【解决方案1】：

DROP PROCEDURE IF EXISTS `add_Order`;
DELIMITER $$
CREATE PROCEDURE `add_Order`(
    IN custid int,
    IN productid int,
    IN storeid int,
    IN  empid int,
    IN quantity int,
    IN R_payment char(10),IN date date
)
BEGIN
    INSERT INTO Orders(custid, empid, storeid, orderdate) values (IN_cust,IN_empid, IN_storeid, IN_date);
    INSERT INTO Order_Product(orderid, productid, quantity, RegisterPayment) values (IN_orderid, IN_productid, IN_quantity, IN_R_payment);
END
$$

DELIMITER ;

【解决方案2】：

使用分隔符 //

DELIMITER $$
DROP PROCEDURE IF EXISTS `add_Order` $$
    create procedure add_Order(IN custid int, IN productid int, IN storeid int, IN 
    empid int, IN quantity int,
    IN R_payment char(10), IN date date)
    begin
    insert into Orders(custid, empid, storeid, orderdate) values (IN_cust, 
    IN_empid, IN_storeid, IN_date);
    insert into Order_Product(orderid, productid, quantity, RegisterPayment) 
    values (IN_orderid, IN_productid, IN_quantity, IN_R_payment);
    end $$
DELIMITER ;
