> Cf discussion on DERBY-5545 with John Hendikx.
> Quote from SQL standard:
> In section 16.7 <rollback statement>, section General Rule 3) <savepoint specified>,
clause g) reads:
> "For every open cursor CR in any SQL-client module associated with the current SQL-transaction
that
> was opened subsequent to the establishment of S, the following statement is implicitly
executed:
> CLOSE CR"
> I take that to mean that the cursor should remain open iff it was established prior to
the savepoint, and, by analogy, the JDBC result set should stay open too.
> and clause h):
> "The status of any open cursors in any SQL-client module associated with the current
SQL-transaction
> that were opened by the current SQL-transaction before the establishment of S is implementation
defined. "
> We could allow result sets to stay open since the current behavior closing them maybe
be unexpected for users, cf. DERBY-5545.
