With the most current drivers, cursors will only be used to
incrementally fetch data when all of these conditions are true:

   - a positive fetchsize has been set via setFetchSize()
   - autocommit is off
   - the resultset type is TYPE_FORWARD_ONLY
   - you are connecting to a 7.4 or above server
