Hi,
where if @param1 <>0   left(value1,4)=@param1
otherwise don't execute this part in the where condition
How to write the query?

Soumya

What I have tried:

where LEFT(ISNULL(value1, 0000), 4) =

CASE
WHEN @param1 <> 0 THEN CAST(@param1 AS NVARCHAR(12))
END	


But this won't execute if
@param1
=0

SQL
WHERE ((@PARAM1<>0 AND left(value1,4)=@param1) OR @PARAM1= 0)

Try following-
SQL
WHERE (@param1 == 0) OR (LEFT(ISNULL(value1, 0000), 4) =@param1)


Logical OR does the trick here. When value of @param1 is 0 it will not execute the second part.

Hope, it helps :)
Please let me know if this doesn't help.
