This way I could insert new records, but not view them in table mode - only in a view or query.

the :oo option still exists, but it uses the pure-java driver, so you
would not be able to use embedded.

The defaultHoldable option sets the default ResultSet holdability to
HOLD_CURSORS_OVER_COMMIT, which means that the resultset is not closed
at commit.
