Using more than one case when statement

Question

Hi there,
I have a question on using case when statements.
Currently I have a table where it shows me mulitple dates.
Order Saledate TransferDate StartDate Enddate GetDate
I have created a where statement to show me records against the transferdate dependant if it appears within the date range of the year, or if it appears within the startdate and today's date.
(lpatran.trandate between targets.startdate
and (case when targets.enddate < getdate() then targets.enddate else getdate() end))
However on some of the records the transfer date is null, and so they want to use the saledate as the date to use.
So I created
(case when Lpatran.trandate is not null then (Lpatran.trandate between targets.startdate
and (case when targets.enddate < getdate() then targets.enddate else getdate()))
else (lpatran.saledate between targets.startdate
and (case when targets.enddate < getdate() then targets.enddate else getdate())) end )
However it gives me an incorrect syntax near the word ‘between ‘ 
Is there a simple fix for this or does sql not allow me to do this?

Answer 1

I have created a new column called transferdate and done a case when statement
CASE
WHEN lpatran.trandate
IS
NULL
THEN lpatran.saledate
ELSE lpatran.trandate
END
AS Transferdate,
Then created a temptable and did a select * from temptable.  Created a where statement from transferdate, which does work and gives me the correct data. 
TransferDate between startdate
and(case
when enddate
<
getdate()
then enddate
else
getdate()
end))
However I wanted to know if there was a way of obtaining the same data without having to use the temptable ?
