What have you done so far? Where are you stuck?

This is pretty basic...so basic i think im over complicating the answer. For example all you would have to do is the following query and grab the "answer" using your preferred data access layer

SELECT
CASE
WHEN COUNT(*) = '0' THEN 'THERE ARE NO NULL ROWS'
ELSE 'CONTAINS NULL ROWS' END AS NullRowCounter
FROM YourTableNameHere WHERE FileNameThatShouldBeNull IS NULL
