I need help! I have a Category parameter requirement. It has 200 values. I want to pick up all on "null" selection (I know it is crazy). otherwise filter based on category (cat1, cat2, etc).
I am not getting desired result using parameter below.
Where Category in (@Category) or Category is null (I am getting zero records instead of all). Is it possible using IIF or Case condition??
Thanks in advance for your help!
