[AccessD] Running sum in a query without DSUM

Thanks Jim.
That makes sense but it still essentially does a dsum in the embedded select
statement. It then runs very slowly for large tables.

Thanks

Here is some a method from a query samples database I got from Lord knows
where. HTH

SELECT [Order Details].OrderID, Sum([UnitPrice]*[Quantity]*(1-[Discount]))
AS OrderTotal, (SELECT Sum(UnitPrice*Quantity*(1-Discount)) FROM [Order
Details] OD WHERE OD.OrderID <= [Order Details].OrderID) AS RunningTotal
FROM [Order Details]
GROUP BY [Order Details].OrderID;

Any way to do a running sum in a "query" without having to deal with the
overhead of a domain function (Like DSUM)?
