Question

我的查询有点长，所以我将尝试使内容简短，只讨论相关信息。我有一列称为Total_Returned_Value。我想对所有单个返回值求和以获得所有返回的最终总返回值。由于表的结构，该列具有重复项，因此我不能仅对该列进行求和。我想根据另一个名为“ Customer_Purchase_Order_Number”的“ id”类型列对该列求和，其中仅对每个采购订单号之一求和。

这就是我的做法。

,rn = ROW_NUMBER() OVER (PARTITION BY Customer_Purchase_Order_Number ORDER BY Customer_Purchase_Order_Number)

,SUM(CASE WHEN rn = 1 then rh.Total_Returned_Value ELSE 0 END) OVER (PARTITION BY rh.Customer_Number) as Total_Returned_Values

因此，它按Customer_Purchase_Order_Number进行组织，为每组相等的数字分配一个行号，并且仅将行号= 1的那些相加。

似乎很简单。但是，出现错误“无效的列名'rn'。”。如果我尝试将行号选择语句直接放入case语句中，则表明我不能在聚合中包含聚合。有谁知道该怎么办？

这是我的完整代码。

我已解决您的查询。您不能将RN用作别名列名称，因此请完全替换rn，它将起作用

DECLARE @LocalCompanyCode VARCHAR(5)
SET @LocalCompanyCode = '03'
DECLARE @LocalDivisionCode VARCHAR(5)
SET @LocalDivisionCode = '001'
DECLARE @LocalFROMDate DATETIME
SET @LocalFROMDate = '2/04/2019'
DECLARE @LocalToDate DATETIME
SET @LocalToDate = '2/08/2019'
SET NOCOUNT ON;

WITH rh AS

        ,rh.Return_Number
        ,(rh.Total_Value-rh.Freight_Charges) as Returned_Value
        ,rh.Freight_Charges
        ,rh.Remarks
