SQL Query To Return Running Subtotal - Year to Date

Hello,

Data -
ID  Y_M       Revenue
1   201201  60
1   201202  50
1   201203  60
...
1   201212  10
1   201301  60
1   201302  20
1   201303  40
1   201304  10
...
2   201201  60
...

Result:
Data -
ID  Y_M       R  YTD
1   201201  60   60
1   201202  50  110
1   201203  60  170
...
1   201212  10  480
1   201301  60   60
1   201302  20   80

Is it posible to have a query to return Year-to-Date number for each row
(meaning if its March - the YTD is a sum of Jan-Feb-March for that year)?
Ultimately i would need a YTD/Previous Year YTD - but I don't think that it's possible in a single query, or is it?

Thank you

it is very important for this answer to know what version of SQL Server you are using.

It is possible to produce running totals, the method used differs (with older versions it is harder and less efficient).

please specify the version(s)

As you have your date embedded in the table as an integer, try this (assuming that your table is called Revenue - you didn't say):

select r.id, r.Y_M, r.R, (	select sum(R) 
					from dbo.Revenue 
					where	Y_M <= r.Y_M 
						and	Y_M > ((r.Y_M / 100)*100)	
				)	
from dbo.Revenue r
where ID = 1
group by id, Y_M, R

Just my humble best    <grin>

I would imagine that you'll want to put it into a procedure and call the procedure with the year number and the ID number ...
