[/code]

Now what i want to do is this ...

UCOA is to be updated with the average of all previous transactions where the climstid and isin_id are the same.

example

take case where holdid(transaction no) in the sample data is 14.
What i need is a query which will sum up the data in the tran_value column upto holdid 5.

Again I need a set based solution. Gurus .. please help

Attitude is everything

update cube_fact_table
set UCOA = z.total
FROM cube_fact_table y JOIN (
SELECT b.HoldID,b.ISIN_ID,b.CLIMSTID,SUM(a.Tran_Value) As total
FROM cube_fact_table a join cube_fact_table b on a.ISIN_ID = b.ISIN_ID AND a.CLIMSTID=b.CLIMSTID and a.HoldID < b.HoldID
group by b.HoldID,b.ISIN_ID,b.CLIMSTID) z
ON y.ISIN_ID = z.ISIN_ID AND y.CLIMSTID = z.CLIMSTID AND y.Holdid = z.holdid

Thanks ... but that misses out on the first record


(
select 
	HOLDID, 
	(
		select 
			sum(tran_value) 
		from 
			cube_fact_table 
		where 
			holdid <= b.holdid 
			and isin_id = b.isin_id 
			and climstid = b.climstid
	)/holding "UCOA"
from 
	cube_fact_table b
)

This worked ...

My understanding is that you want to sum everything that came before. Therefore line one will not be updated as there is nothing before.

Sum includes the current transaction also ... :) ..

Sorry my mistake... I didn't read it that well. Also you ask for average not sum.. try this

update cube_fact_table
set UCOA = z.total
FROM cube_fact_table y JOIN (
SELECT b.HoldID,b.ISIN_ID,b.CLIMSTID,AVG(a.Tran_Value) As total
FROM cube_fact_table a join cube_fact_table b on a.ISIN_ID = b.ISIN_ID AND a.CLIMSTID=b.CLIMSTID and a.HoldID <= b.HoldID
group by b.HoldID,b.ISIN_ID,b.CLIMSTID) z
ON y.ISIN_ID = z.ISIN_ID AND y.CLIMSTID = z.CLIMSTID AND y.Holdid = z.holdid
