所以我有一张桌子，上面有一堆订单。每个订单都有一个采购订单编号（第5列）。我的表包含每个订单号的所有行值。例如，订单3130148有5个已订购的商品，因此它有5行。

现在我正在尝试计算总数。像订购的总数量，使用的每个运输代码的总和，等等。我遇到的一个问题是所有订单的总价值之和。我的表有一个订单值列。但是，由于该表是按每个订单项划分的，所以我不能仅对整个Order_Value列进行汇总，因为有很多重复项（每行一个）。因此，我需要对采购订单号不同的所有订单值求和。
这是我使用的编码行，但无法正常工作
Sum(Order_ValueG) FROM (SELECT MAX(Order_Value) AS Order_ValueG FROM T GROUP BY Customer_Purchase_Order_Number) T2 --AS Total_Orders_Value
我在这里找到了此代码-> SUM(DISTINCT) Based on Other Columns
我尝试过多次更改线路，但似乎无法正常工作。我收到有关AS关键字的错误。
这是完整的代码（我在begin语句之后选择所有内容并运行）

我认为该错误与尝试在子查询中使用表T有关。如果这是一个简单的查询，那么我只能使用GROUP BY Customer_Purchase_Order_Number，但是由于我要选择多个内容，因此无法正常工作。
答案 0 :(得分：0)
好的，您发布的代码太破损而无法使用，并且您尚未共享DDL或原始数据，因此，我将为您提供伪代码方面的指导。
因此，我需要对采购订单号不同的所有订单值求和。
您可以执行以下操作：
SUM(CASE
WHEN ROW_NUMBER() OVER (PARTITION BY PurchaseOrderNumber ORDER BY SomeColumn)=1 THEN OrderValue
ELSE 0
END) AS SumValues
