Question

i have error on my sql query.

my query :

SELECT sum(billsItems_Quantity) as TotalQ , 
    sum(billsItems_ItemDiscount) as TotalD , 
    sum(billsItems_ItemTotal) as TotalI , 
    bills.bills_ID , 
    billsitems.billsItems_BillItemSerial , 
    bills.bills_CashierID , 
    bills.bills_StoreID , 
    billsitems.billsItems_Unit , 
    billsitems.billsItems_Price 
FROM bills , billsitems 
WHERE bills.bills_ID = billsitems.billsItems_BillItemSerial
  and bills.bills_CashierID = '".$id."'
  and bills.bills_StoreID = '$ausers_StoreId'

Ok I think I understand your problem. Are you usign SQL Server 2005 or newer?

If so, you can do this with the “OVER” clause, wich will let you do sums and get all the other columns. here’s a way to do this

SELECT sum(billsItems_Quantity) OVER (PARTITION BY /*group by columns for the sum here*/) as TotalQ , 
   sum (billsItems_ItemDiscount) OVER (PARTITION BY /*group by columns for the sum here*/) as TotalD , 
   sum (billsItems_ItemTotal) OVER (PARTITION BY /*group by columns for the sum here*/) as TotalI , 
   bills.bills_ID , billsitems.billsItems_BillItemSerial , bills.bills_CashierID , 
   bills.bills_StoreID , billsitems.billsItems_Unit , billsitems.billsItems_Price FROM bills , 
   billsitems 
WHERE bills.bills_ID = billsitems.billsItems_BillItemSerial
  and bills.bills_CashierID = '".$id."'
  and bills.bills_StoreID = '$ausers_StoreId'
order by billsitems.billsItems_Unit
