Which method are you using to perform the INSERT or DELETE?
You should be using executeUpdate() rather than executeQuery() because
executeUpdate() doesn't expect a ResultSet to be returned, and
executeQuery should throw an SQLException when it fails to get one.
An alternative (if you don't know what the query will be) is execute(),
but you then have to handle ResultGet accordingly.
