Question

我需要知道查询中的问题在哪里，我该如何解决？

SQL查询：

SELECT 
    P.NameAr, P.NameEn,
    Sum(p.OrderQty) AS SumQty , 
    Sum(p.OrderQty * P.NewPrice) AS SumQtyPrice , 
    ROW_NUMBER() OVER(ORDER BY D.ProductID ASC) AS Number,
    'Soon' AS ColSoon
FROM OrderMasters M
INNER JOIN OrderDetails D ON D.OrderMasterID = M.OrderMasterID
INNER JOIN Products P ON P.ProductID = D.ProductID
INNER JOIN Categories C ON C.CategoryID = P.CategoryID

GROUP BY P.NameAr, P.NameEn
Order By D.OrderDetailsID

错误消息：

Msg 8120，Level 16，State 1，Line 7

Column＆＃39; OrderDetails.ProductID＆＃39;在选择列表中无效，因为它不包含在聚合函数或GROUP BY子句中。

当我删除包含@RowNumber代码的行执行时没有问题，但我在查询中需要它。

Answer 1

您不能按字段申请不属于分组的字段;

所以，你应该按照条款

更改你的订单

SELECT 
    P.NameAr, P.NameEn,
    Sum(p.OrderQty) AS SumQty , 
    Sum(p.OrderQty * P.NewPrice) AS SumQtyPrice , 
    ROW_NUMBER() OVER(ORDER BY P.NameAr ASC) AS Number,
    'Soon' AS ColSoon
FROM OrderMasters M
INNER JOIN OrderDetails D ON D.OrderMasterID = M.OrderMasterID
INNER JOIN Products P ON P.ProductID = D.ProductID
INNER JOIN Categories C ON C.CategoryID = P.CategoryID

GROUP BY P.NameAr, P.NameEn
Order By P.NameAr

我将P.NameAr作为订单字段提供示例。

Answer 2

SELECT 
    P.NameAr, P.NameEn,
    Sum(p.OrderQty) AS SumQty , 
    Sum(p.OrderQty * P.NewPrice) AS SumQtyPrice , 
    ROW_NUMBER() OVER(ORDER BY D.ProductID ASC) AS Number,
    'Soon' AS ColSoon,
    D.OrderDetailsID
FROM OrderMasters M
INNER JOIN OrderDetails D ON D.OrderMasterID = M.OrderMasterID
INNER JOIN Products P ON P.ProductID = D.ProductID
INNER JOIN Categories C ON C.CategoryID = P.CategoryID

GROUP BY P.NameAr, P.NameEn,D.ProductID,D.OrderDetailsID
Order By D.OrderDetailsID

我解决了这个问题所有提示

Answer 3

GROUP BY也应包含D.PRODUCTID：

group by p.NameAr, p.NameEn, d.ProductID

SQL SERVER，我的查询中的错误
