In order to know how many rows are returned, you'd have to check @@ROWCOUNT after the query runs. So the below would appear in a different result set.

IF @@ROWCOUNT = 0
SELECT '\'

Perhaps someone else has a better solution though.

Hello Tara,

It is always one row, it is either one row of info or nothing.

when it is nothing i want to show just the '\' backslash.

Thank you.

If its a single row, then how about:


select top 1 *
from	(	select	FilePath [FilePath], 
			0 [r]
		from	tab_doc_repository 
		where	docid = 0
		union all
		select	'/', 
			1
	)d
order
by	[r] asc
