Found out that resultset.getInt(x) will return 0 when in fact there was a null
(no result). Changed to not start IDs at 0 so as to avoid unexpected results,
but a 0 can still be confusing and ambiguous.
By using an Integer return type, a NULL could be passed to the caller and
handled appropriately.
