Dsum Problem with date criteria

[naveen prasad]

Hi all,
Kindly solve my problem.

I have 2 tables stock_received , stock_utilized.

stock_received fields -- date,3pcs,4pcs,boxes.

stock_utilized fields -- date,3pcs,4pcs,boxes.

I have successfully made a query to get the the current stock in hand as

select sum(3pcs)- dsum("3pcs","stock_utilized"),
sum(4pcs)-dsum("4pcs","stock_utilized"),sum(boxes)-dsum("boxes","stock_utilized") from stock_received ;

Here i have a complex problem, I cant make query with date criteria.

for example 01/05/2010 to 30/05/2010

I want to get how much stock received in that dates and how much was
utilized and how much is balance.

kindly help me how should i write query.

It would be easier and faster (at execution time) to use a single table
(with negative quantity for utilized items).

SELECT [3pcs] AS qty, [date] AS dateStamp FROM stock_received
UNION ALL
SELECT -[3pcs], [date] FROM stock_utilized


as a saved query will do that 'table' (without indexes, though), assume it
is called q1, then:

SELECT SUM(iif(qty>0, qty, 0)) AS receivedQty,
SUM(iif(qty<0, -qty, 0)) AS utilizedQty,
SUM(qty) AS brutQty
FROM q1
WHERE dateStamp BETWEEN #01/05/2010# AND #30/05/2010#

should to for the given date interval.
