Is it any overhead on the backend side related to retrieving results through the use of cursors(ignoring the extra bytes sent) ? If you only use a fragment of the data in the result set this method would of course be faster, but in other situations I'm concerned that you will only add overhead to the ResulSet.next() method(with familiy). But you mentioned alternate implementation, so that would probably mean that the user can choose the appropriate implementation for his application ? Regards, Gunnar
