Group By 子句中的列名无效错误

Question

我正在尝试为 rdlc 报告创建一个 Sp。其中我使用了许多用户定义的函数进行计算。但是当我试图在 group by 子句中使用函数别名时，它给出了一个错误“消息 207，级别 16，状态 1，第 14 行无效的列名‘CommPaid’”下面是我的查询

SELECT        Employee.FirstName AS Tech, CommissionStructure.Name AS Commission, '$ ' + CONVERT(varchar(8), SUM(WorkOrderPayment.PaymentTotal)) 
                     AS TotalSales --, ISNULL(SUM(PurchaseOrder.AmountPaidToSupplier), 0) AS POAmount, ISNULL(SUM(WorkOrderPayment.TOC),0) AS TOC,
                    -- SUM(dbo.GetCashInvoiceAmount(WorkOrderPayment.WorkOrderPaymentID)) AS CashInvoice, ISNULL(SUM(dbo.GetSecTechAmount(WorkOrderPayment.WorkOrderID)),0) AS SecTechAmount
                    ,dbo.GetCommission(SUM(WorkOrderPayment.PaymentTotal),SUM(dbo.GetCashInvoiceAmount(WorkOrderPayment.WorkOrderPaymentID)),ISNULL(SUM(PurchaseOrder.AmountPaidToSupplier), 0),ISNULL(SUM(WorkOrderPayment.TOC),0),ISNULL(SUM(dbo.GetSecTechAmount(WorkOrderPayment.WorkOrderID)),0),CommissionStructure.CommissionPercentage) As CommPaid

FROM            WorkOrder INNER JOIN
                     WorkOrderPayment ON WorkOrder.WorkOrderID = WorkOrderPayment.WorkOrderID INNER JOIN
                     Employee ON WorkOrder.empID = Employee.empID INNER JOIN
                     CommissionStructure ON Employee.CommissionStructureID = CommissionStructure.CommissionStructureID INNER JOIN
                     [User] ON Employee.UserID = [User].UserID LEFT OUTER JOIN
                     PurchaseOrder ON WorkOrderPayment.WorkOrderPaymentID = PurchaseOrder.WorkOrderPaymentID

WHERE        (WorkOrder.OrderStatusID = 3) AND (WorkOrder.Deleted = 0) AND ([User].Active = 1) AND (CONVERT(varchar, WorkOrder.ScheduleStartTime, 101) 
                     >= '10/01/2013') AND (CONVERT(varchar, WorkOrder.ScheduleStartTime, 101) <= '10/24/2013')

GROUP BY Employee.FirstName, CommissionStructure.Name,CommPaid

当我删除函数别名时，它会给出另一个明显的错误。

"Msg 8120, Level 16, State 1, Line 4
Column 'CommissionStructure.CommissionPercentage' is invalid in the select list because it is not contained in either an aggregate function or the GROUP BY clause."

Answer 1

将您在 SELECT 中使用的复杂函数也放入 GROUP BY 中：

GROUP BY 
... 
,dbo.GetCommission(...

关键是，您的别名在 GROUP BY 处理期间不可用。SELECT 通常是要执行的语句的最新部分...
