These tests are easy to do: if the statement was a query and thus 
offered a ResultSet, then execute() returns true.  If instead it
returns false, then I'd check for updateCount() and getGeneratedKeys().

Except that I could only request reporting of generated keys, if I knew
beforehand that I wouldn't need any isolation,etc.-flags for the select-
case.
