Question

我想对Northwind数据库进行此类修改

将Chocolade添加到客户ALFKI的所有订单中，而不是包括它

（我试图使用插入，不幸的是我失败了。）

Answer 1

我从这里（https://northwinddatabase.codeplex.com/）采用了数据库模式。因此，逻辑很简单：找到客户'ALFKI'的所有订单，找到巧克力productID并将所有这些信息添加到表Orders_Details。

INSERT INTO Order_Details(orderID, productID, UniPrice, Quantity, Discount)
SELECT O.orderID,
       pr.productID,
       <your price>,
       <your quantity>,
       <your discount>
FROM Orders AS O, 
    (SELECT TOP 1 productID FROM Products WHERE productName like '%Chocolate%') AS pr
    JOIN Customers AS C ON O.customerID = C.customerID
WHERE C.companyName = 'ALFKI'

Northwind查询和修改
