Force a SQL Server query to return no rows

Question

I have the following query:

SELECT 
     CASE
          WHEN ([DBO].fn_WorkDays(GETDATE(), DATEADD(d, 1, EOMONTH(GETDATE()))) = 2)
               THEN 1
     END

That should return 1 if the condition is true (obviously), but I want it to return nothing (no rows) if false. Instead, it's returning a null row. How do I force it to return 1 or nothing?

Answer 1

How about

IF [DBO].fn_STRS_WorkDays(GETDATE(), DATEADD(d, 1, EOMONTH(GETDATE()))) = 2
    SELECT 1

Answer 2

select * from dbo.table where 1=0
