TSQL Case in where statement if parameter is null

Question

I have a SP that gives me a lot of hard times.

The sp gets a two parameters @madeByUserId and @reportedByUserId. I want to have something like:

 select          


        

Answer 1

I think this will give you what you're after.

IF (@reportedByUser IS NULL)
    select * from table 
    where MadeByUserId = @madeByUserId
ELSE
    select * from table 
    where MadeByUserId = @madeByUserId and ReportedByUserID = @reportedByUserID)
