Levi:
If you are wanting to use "isnull" you might also be able to do something like:
Code Snippet
isnull (cast(theValue as varchar), '--')
like for instance in:
Code Snippet
select isnull (cast(theValue as varchar), '--')
as convertedValue
from ( select 14 as theValue union all
select null
) a
/*
convertedValue
------------------------------
14
--
*/
