錯誤！ -不能在用於GROUP BY子句的group by列表的表達式中使用聚合或子查詢

Question

我收到此錯誤：無法在用於GROUP BY子句的group by列表的表達式中使用聚合或子查詢。

我環顧四周，但找不到任何可以幫助我的情況。

我正在使用SQL Server 2012

Answer 1

您的GROUP BY中的case語句中有子查詢。 例如，查看case語句的第一部分：

When Commodities.ShippedReceivedId = 'R' And Commodities.ForeignDomesticId = 'F' Then
 Case When Commodities.Amount Is Null Or Commodities.Unit Is Null Then Null
    Else
    Round (Commodities.Amount/Case When Commodities.Unit = 'B' Then (Select BushelFactor From CommodityCode
          Where CommodityCode.CommodityCode = Commodities.CommodityCode)
    Else (Select ShortTonFactor From Unit
          Where Unit.Unit = Commodities.Unit) End,2
     )
     End
  Else 0
  End,

首先有兩個選項，以Select BushelFactor...和Select ShortTonFactor...開頭，因此您必須將其刪除。

我很快就重新格式化了您的查詢並刪除/評論了其中的一些問題：

SELECT --DISTINCT - do you really want DISTINCT?

我不希望這會產生您想要的答案，但是由於邏輯已被簡化，因此它可能更容易發現原始查詢的問題所在？
