Also I hope, you took into consideration that this way you will have to
write a copy constructor for DriverResultSet which will duplicate the
pointers correctly in that class. With the default copyconstructor will
segfault.
Just a simple example:

{ DriverResultSet drs = xy.getResultSet();    <-- copy constructor
}
//drs will be destroyed at this point => destructor will be called,
pointers like data and fields will be destructed.
a call again to the same xy.getResultSet() later in the code will lead
to segfault if the DriverResultSet copy constructor is not implemented.

Also duplicating large DriverResultSet takes a long time ....
