while downvoting, it should also ask for a comment for the reason and might be display as reason for downvoting to the author (it can still be anonymous)?

Hi Joe, You can use following query:

SELECT ISNULL( (SELECT File_Name
FROM Files
WHERE File_Name = @FileName1),1)

This would solve your problem, in case there is no result, it will return you 1 otherwise the matching result.
