Good Day To All,
I'm working on a budgetreport that ask the user to enter the up to date.
If the user enters let's say 08/2012 I'm able to get actual data from the begin of the beginning of the year to the end of the month of 08/2012.
My problem is now the user wants to get the budgeted data for the remaining part of the year. For this example I need 09/2012 through 12/2012 budget data.

This is what I have so far but doesn't work properly.

sum(CASE When t.uMonth between dateadd(m,11,dbo.get_boy(dateadd(m, month('#date2#') + 1,'#date2#'),p.hmy)) and dateadd(m,11,dbo.get_boy(dateadd(y,1,'#date2#'),p.hmy))
THEN
CASE a.iNormalBalance WHEN 1
THEN l.dpercent*.01*isnull(-t.sBudget,0)
ELSE l.dpercent*.01*isnull(t.sBudget,0) END
ELSE 0 END ) data8,




***dbo.get_BOY is a function that get Beginning Of Year
*** #date2# ***** is a parameter that is entered by the user
**** data 8 is the placeholder for the end result.
**** a.iNormalBalance is a flag field when 1 do something when it's 0 do something else
*** u.month is the month I test against from the enter parameter
Thanks

Instead of using UDFs (dbo.get_BOY) that will reduce performance, try looking at this article.

Agreed that the BOY function is a waste of CPU cycles when the conversion is quite easy as follows:


SET DATEFORMAT MDY
SELECT BOY=DATEADD(year, DATEDIFF(year, 0, MyDate), 0)
,EOY=DATEADD(year, 1, DATEADD(year, DATEDIFF(year, 0, MyDate), 0))-1
FROM (SELECT CAST(REPLACE('08/2012','/','-01-') AS DATETIME)) a(MyDate)





My mantra: No loops! No CURSORs! No RBAR! Hoo-uh!

My thought question: Have you ever been told that your query runs too fast?

My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.


Need to UNPIVOT? Why not CROSS APPLY VALUES instead?
Since random numbers are too important to be left to chance, let's generate some!
Learn to understand recursive CTEs by example.
Splitting strings based on patterns can be fast!

I don't want to post it again, so Google around here for "Report_Periods"; it is a basic look-up table for temporal durations. Don't use UDFs; they screw up the optimizer, cannot port and are a bitch to maintain.


Please ignore this stupid remark!
Although in your case UDF is not really required, they are very helpful and useful where appropriate.
UDF is a powerful feature of SQL Server and when UDFs implemented correctly, they do not screw up the optimiser. If you thinking to port your system into other RDBMS, believe me, having UDFs will not be your main concerns. They are not harder to maintain than stored procedures.
Mr. Celko hates many different features of SQL Server (which he cannot comprehend) and he is very vocal about it...

Easy, big guy. You're right but that's something that he would say. ;-)

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
Although they tell us that they want it real bad, our primary goal is to ensure that we dont actually give it to them that way.
Although change is inevitable, change for the better is not.
Just because you can do something in PowerShell, doesnt mean you should. Wink

I've spent 5 minutes to choose the word from the list of "wrong", "irrelevant" and "stupid".
Then tossed my lucky three-side coin and got the one...
Hehe

You should have used a nullable column, and just removed the adjective entirely...

Sorry, but it's not nullable in my database. The remark was stupid, why not qualify it as such?
Actually, it was the most polite adjective I could come up with...
