Sir ,
I think that what you have given is to lengthy process i give procedure of my way how i calculate running total
-------------------
drop TABLE #data -- drop temp table if exists
CREATE TABLE #data (myctr INT IDENTITY,chrfolioid VARCHAR(20),numgrandtotal NUMERIC(18,2),running NUMERIC(18,2))
INSERT INTO #data (chrfolioid,numgrandtotal)
SELECT chrfolioid ,numgrandtotal
FROM tARHeader t
ORDER BY t.chrFolioID ,t.dteTxnDate
DECLARE @ctr AS INT
DECLARE @running NUMERIC(18,2)
DECLARE @oldfolioid AS VARCHAR(20)
SET @ctr = 1
SET @running = 0
SET @oldfolioid = ''
WHILE @ctr <= (SELECT COUNT(*) FROM #data)
BEGIN
IF @oldfolioid <>(SELECT chrfolioid FROM #data WHERE myctr = @ctr)
BEGIN
SET @running= 0
SET @oldfolioid = (SELECT chrfolioid FROM #data WHERE myctr = @ctr)
END
UPDATE #data SET running = (SELECT SUM(numgrandtotal)
from #data
where myctr <= @ctr and chrfolioid = @oldfolioid
GROUP BY chrfolioid ) WHERE myctr = @ctr
SET @ctr = @ctr + 1
PRINT @ctr
END
SELECT * FROM #data ORDER BY 1,2

Thank you for the feedback and the code... but have you actually tried such code for performance sake?

Sir ,

I have not seen any sake in performance of executing query , can you help it out where I doing Wrong

I tried this statement on a table which having 10 years of data and in each year there is n numbers of transaction in each folio code and there are more then 5000 folioid in in each accounting year ,my server configuration if MSDE setup of SQL server 2000 and system having memory of 2GB with core2DUO CPU

sir ,

Depend on party turnover if 2 rows return two rows and if 200000 return 200000 with running total

Perhaps you don't understand. I'm trying to setup an example based on what you said so you can see. I asked a simple question... how many rows in total for all 10 years?

Jeff,

Wouldn't a million row setup show what you are talking about? Of course, you could make it ten million.

Heh... it absolutely would... but he's using MSDE 2000 and, since it has some limits, I didn't want the test table to be a source of irritation.
