Hi All,
How Do we Sum up the Values As Per the Date in a Particular Month ,I am Designing the Report wher i have to Drill Down U pto the Date Level, I Need To Sum up the Percentage value From th Previous Dates and So on ...it has to continue.
If i take up the particular Date say 4/July/2010 -it should show me the value summing up all the Previous date that comes in the July Month Say as 48 %
when i drill down up to the level of the particular date ,it should show me the value upto date(i;e sum of all the values) instead of value on that date.
Please Let me know how can i write the sql query to get this result or is it possible to achieve in ssrs directly.
Thanks & regards

I don't use SSRS but isn't there a RunningTotal function in SSRS?

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.

Yes, there is a 'RunningValue' aggregate function that can be used for this.

Post some sample data along with your query.

For your own education,look up the ANSI/ISO Standard syntax for
SUM(<expression>)
OVER (PARTITION BY ..
ORDER BY ..
[ROW|RANGE] ..)
That last clause is how you do running computation in better SQLs.

Joe,

would you mind showing an SQL 2005 compliant example of your general code applied to the following table (expected result: running total for SomeValue order by SomeID)?

DECLARE @tbl TABLE

(

SomeID INT IDENTITY(1,1),

SomeValue INT

)

INSERT INTO @tbl(SomeValue)

SELECT 1 UNION ALL

SELECT 3 UNION ALL

SELECT 5 UNION ALL

SELECT 7

SELECT *

FROM @tbl

Yep... and someday they'll make that work correctly in SQL Server. 😉

A wise choice... how is it in the area of performance?
