Hi,
I need to make the following query into a function- I thought it'd be easy, but I keep getting errors. (maybe starting too late at night?)
Can someone help me? Thanks, J
select
cASE WHEN ( MONTH(GetDate())<6 and Day(GetDate())<16)
then
year(getdate())-1
Else
year(getdate()) END as 'year'

I got no errors when running what you posted.

Right- it works fine as a select statement. I want to take it and turn it into a function so I only need to call it one time.

GETDATE() won't work inside an SS2000 function because of silly rules about being non-deterministic and all... you need to make a view for a simple GETDATE() ...

CREATE VIEW dbo.Now

AS

SELECT GETDATE() AS Now

Then, your code for the function would look like this...

SELECT CASE

WHEN MONTH(Now)<6 AND DAY(Now)<16

THEN YEAR(Now)-1

ELSE YEAR(Now)

END AS 'YEAR'

FROM dbo.Now

I believe SS2005 allows GETDATE() in a function, though.

Ok... so did that do the trick for you or what? A little feedback goes a long way around here...

Yes, thanks for your help- I did get it working. Sorry it took so long to respond- I'm telecommuting after coming off maternity leave and am working some very whacky hours!

Heh... going back to the other posts, I see that now...

Hope things are going well for Mother and Child.
