Question

我有一个返回一些列的数据集。我正在编写一个查询，该查询将显示另一列买方的每一行的日期时间范围内的两列TotalQty和TotalValue的总和。这意味着总行数将是不同买家的数量。但不知何故，我的查询不是在日期时间范围内对行进行求和。它显示了每个日期的所有值。我怎么解决这个问题？我试过这个 -

 Create PROCEDURE [dbo].[spRPTMonthWiseProductionSummaryFORATL]

       @ToDate = DateAdd(d,-1,DateAdd(m,1,Convert(Datetime,@MonthName)))

Group by year(UseDate),month(UseDate),UseDate,Buyer

End

我收到这样的数据 enter image description here

对于买方s.OLIVER，m1qty，m1value和m2qty，m2value的值太多了。但是m1qty，m1value和m2qty的1个值应该是1的值，“s.Oliver”的m2值是在条件条件下指定的日期范围的总和。

Answer 1

您的程序相当大，需要一些时间才能理解完整的逻辑。但是，有一件事似乎可能是问题，它是你的CASE表达式。它们可能应该在聚合函数中。我的意思是，而不是像这样写它们：

CASE WHEN UseDate>=@FromDate And UseDate< @FromDate2 THEN SUM(TotalQty) END

你应该（可能）这样写：

SUM(CASE WHEN UseDate>=@FromDate And UseDate< @FromDate2 THEN TotalQty END)

然后您还应该从GROUP BY中移除UseDate（但可能同时保留year(UseDate)和month(UseDate) - 再说一次，如果不深入了解逻辑，很难说。）

Answer 2

如果我粗略地简化了您的查询，我会在group by中看到一些奇怪的内容。

 SELECT B.Buyer
   FROM 
  (
   SELECT Buyer
     FROM 
    (
     SELECT C.Name as Buyer
     FROM ....
    )
  ) B
GROUP BY year(UseDate),month(UseDate),UseDate,Buyer

如果您想要每个买家一行，为什么不将买家列为最高级别？

如果您将group by更改为

，则每位买家可获得一行

GROUP BY Buyer

将日期分组也会为每位买家提供几行，即每个分组日期一行。您的查询似乎想要在不同的列上传播不同日期的结果，因此无需对这些列进行分组。

实际上，您可能希望在之前的一个内部查询中group by Buyer。

在时间范围内的值的总和不起作用
