It is unclear what the differences here are. You haven't shown the
Statement creation and/or execution, so it's possible that you haven't
used setFetchSize or you've specified a scrollable ResultSet. Maybe auto
commit is on. Any of these will cause a cursor not to be used and the
results will be fetched in bulk, so an intermediate commit won't cause any
problems. Maybe the query doesn't retrieve 100 rows, so it doesn't get to
the commit part.
