尝试使用参数和多个连接创建存储过程

Question

我正在尝试创建一个带有一个参数并连接三个表的存储过程：OrdersOrders、Ordered_ProductsOrdered_Products 和 ProductsProducts。我想要所有没有匹配表的表中的列。该参数在 java 中使用，以便客户能够根据其用户 ID 搜索订单。

这是我想出的：

CREATE PROCEDURE sp_seeOrder
    @user_id
AS
    SELECT 
        O.order_id, O.order_quantity, O.user_id, O.Status, O.order_date, 
        O_P.orderID, O_P.product_code, 
        P.product_id, P.product_name, P.price
    FROM 
        Orders AS O
    FULL JOIN 
        Ordered_Products ON O.order_id = O_P.orderID,
    RIGHT JOIN 
        Products P ON O_P.product_code = P.product_id
    WHERE 
        user_id = @user_id;

我收到多个错误：

Msg 156, Level 15, State 1, Procedure sp_seeOrder, Line 4 [Batch Start Line 213]
Incorrect syntax near the keyword 'SELECT'.

Msg 156, Level 15, State 1, Procedure sp_seeOrder, Line 9 [Batch Start Line 213]
Incorrect syntax near the keyword 'RIGHT'.

我做错了什么？

Answer 1

将数据类型放入@user_id 参数中。我假设它是一个 INT，因为它是一个 ID。并删除“ON O.order_id = O_P.orderID”之后多余的 , 。更正后的查询应如下所示：

CREATE PROC sp_seeOrder
@user_id INT
AS
SELECT 
    O.order_id, O.order_quantity, O.user_id, O.Status, O.order_date, O_P.orderID, 
    O_P.product_code, P.product_id, P.product_name, P.price
FROM Orders AS O
FULL JOIN Ordered_Products AS O_P
    ON O.order_id = O_P.orderID
RIGHT JOIN Products P
    ON O_P.product_code = P.product_id
WHERE user_id = @user_id;
