Very right! Will give the getNumRows() a try andsee how it goes.
Thanks again.

(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".
