That may be, but it seems to me that you then are performing two queries for each need to retrieve a record, first to ask if there is any records, and then to ask for the records! (Maybe I am wrong here!!)
I think that querying for the records, checking for the number retrieved, should be the optimal way :) Then always pass the number to the view, and let the view show some message for the user to stop messing around :D or some kinder message like "No information found".
