如何使用SQL在一行中显示数据

Question

我在加入购物篮后订购了产品“Cookie”和“Coffee”。那么这是我的Order表：

然后我编写了如下代码：

SELECT Order.OrderDate
    , User.NAME
    , User.Surname
    , User.Phone
    , User.Adress
    , Product.ProductName
    , Order.Price
    , Order.Piece
    , Cargo.CargoPrice 
FROM Order 
INNER JOIN User ON Order.UserID = User.UserID 
INNER JOIN Product ON Order.ProductID = Product.ProductID 
INNER JOIN Cargo ON Order.CargoID = Cargo.CargoID 
WHERE Order.OrderDate = '2018-02-05 17:30:13.000' 
AND Order.UserID = '1'

所以输出如下：

因此，我的订单总价值必须为90 + 80 + 7 = 177，我想在一行中显示这些值：user name，user surname，total price，{{ 1}}。

Answer 1

我认为这适用于您的问题

SELECT 
      User.NAME
    , User.Surname
    , TotalPrice = SUM((Order.Price * Order.Piece) + MIN(Cargo.CargoPrice) )
    , Order.OrderDate
FROM Order 
INNER JOIN User ON Order.UserID = User.UserID 
INNER JOIN Product ON Order.ProductID = Product.ProductID 
INNER JOIN Cargo ON Order.CargoID = Cargo.CargoID 
WHERE Order.OrderDate = '2018-02-05 17:30:13.000' 
AND Order.UserID = '1'
GROUP BY
      User.NAME
    , User.Surname
    , Order.OrderDate
