我收到此错误：无法在GROUP BY子句列表中使用的表达式中使用聚合或子查询。

我环顾四周，但在我的情况下找不到任何可以帮助我的东西。

我正在使用SQL Server 2012

您的{1}}中的案例陈述中有子查询。例如，查看案例陈述的第一部分：

GROUP BY

有两个开始，从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, 和Select BushelFactor...开始，所以你必须删除它们。

我快速重新格式化您的查询并删除/评论其中的一些问题：

    INNER JOIN CommodityCode cc ON c.CommodityCode = cc.CommodityCode

    INNER JOIN Facility f ON tc.FacilityID = f.FacilityID

    INNER JOIN TransactionFee td ON tc.TransactionID = tf.TransactionID

我不希望这会产生你想要的答案，但是现在逻辑有点简化可能会更容易发现原始查询的错误？
