Group By子句中的无效列名错误

Question

I'm trying to create a Sp for rdlc report. In which I'm using many user defined function for calculation. But when I'm trying to take function alias in group by clause it is givng an error "Msg 207, Level 16, State 1, Line 14 Invalid column name 'CommPaid'" Below is my Query

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

When I removed function alias then it give an other error which is obvious.

"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

Place the complex function you are using in the SELECT also into the GROUP BY:

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

The point is, that your alias is not available during the GROUP BY processing. SELECT is usually the latest part of the statement to be executed...

Answer 2

Remove CommPaid in GROUP BY

GROUP BY Employee.FirstName, CommissionStructure.Name

because by itself it is also an Aggregate field

But if you want the two aggregate fields, that is, TotalSales , CommPaid - you have two options:

Option 1 : Include the complex function in your GROUP BY

GROUP BY Employee.FirstName, CommissionStructure.Name, 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)

Option 2 : Make two Query and JOIN the two, like:

SELECT A.Tech, A.Commission, A.TotalSales, B.CommPaid FROM
(
SELECT   Employee.EmpID,  Employee.FirstName AS Tech, CommissionStructure.Name AS Commission, '$ ' + CONVERT(varchar(8), SUM(WorkOrderPayment.PaymentTotal)) 
                 AS TotalSales 

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
) A

INNER JOIN
SELECT A.Tech, A.Commission, A.TotalSales, B.CommPaid
(
SELECT   Employee.EmpID,  Employee.FirstName AS Tech, 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
) B
ON A.EmpID = B.EmpID
