error with linked server

Hi
when i try to run a query using linked servers, i get the following
error.

Server: Msg 125, Level 15, State 1, Line 1
Case expressions may only be nested to level 10.

I do have more than 10 case statements, it works fine when it is less
than 10. can anyone tell me if there is a way to have more than 10
case statements. thanks alot.

Jay

Since most of your conditions are the same, have you tried something like
this?

Select category, val, Sum(QTY) As QTY , yr
From
(
Select val, QTY2 As QTY,
KEEP = Case
When code in ('004', '005, '003', '017', /* etc. */)
And ((YR > 2003) Or (YR = 2003 And MON > 12))
Else 'Y' End
From
amf a Join linkedserver.source.dbo.table2 b On a.COM = b.COM
Where CATEGORY In ('1') And CODE In ('001','003','004','005')
And b.YR Between 2003 And 2004 And b.MON <= 1
) x

hi
thanks for the suggestion. I have a problem, this is one of the query
where it is all the same, in a few others it varies a lot. i want to
know if the limitaion exists in sql using linked servers ( since it
works fine if i dont use linked servers and have them in the same
server). i want to get aroud this, so that i dont have to change all my
existing queries, and would hamper my using linked server. thanks.. any
suggestion?
