C# 使用C应用程序在asp.net中出现Sql查询错误

我只是尝试使用这个查询按数据网格显示细节

select 
P.Sitename as Site
,P.Vendorname as Vendor
,P.POno,PS.Itemcode as ItemCode
,sum(PS.Quantity) as Qty
,sum(PS.Basic) as Basic
,Sum(PS.DiscountAmt) as [Disc Amt]
,sum(PS.PFAmt) as [PF Amt]
,sum(PS.EDAmt) as [ED Amt]
,sum(PS.VATCSTAmt) as [VATCST Amt]
,sum(PS.Netamt) as Total
,I.Itemname as Itemname
,I.UOM as UOM  
from tbl_Itemmaster I, tbl_Purchaseorder_sub PS,tbl_Purchaseorder P 
where P.POdate between '8/30/2012' and '8/31/2012' 
and PS.status in (4,5) 
and I.Itemidentify=Ps.ITemcode 
and PS.pono=p.POno 
group by PS.Itemcode,P.Sitename,P.Vendorname,I.Itemname,I.UOM   
order by Site,Vendor,ItemCode

但是，我在执行这个过程中遇到了一个错误

"Column 'tbl_Purchaseorder.POno' is invalid in the select list because 
it is not contained in either an aggregate function or the GROUP BY clause."

有人能告诉我如何更正吗

您需要通过CLUSE将POno添加到组中

差不多

select  P.Sitename as Site,
        P.Vendorname as Vendor,
        P.POno,
        PS.Itemcode as ItemCode,
        sum(PS.Quantity) as Qty,
        sum(PS.Basic) as Basic,
        Sum(PS.DiscountAmt) as [Disc Amt],
        sum(PS.PFAmt) as [PF Amt],
        sum(PS.EDAmt) as [ED Amt],
        sum(PS.VATCSTAmt) as [VATCST Amt],
        sum(PS.Netamt) as Total ,
        I.Itemname as Itemname,
        I.UOM as UOM  
from    tbl_Itemmaster I, 
        tbl_Purchaseorder_sub PS,
        tbl_Purchaseorder P

and     '8/31/2012'

group by    PS.Itemcode,
            P.Sitename,
            P.Vendorname,
            I.Itemname,
            I.UOM,
            P.POno <-- You need to add this to your query
order by    Site,
            Vendor,
            ItemCode
