Mamta A. Satoor commented on DERBY-4191:
----------------------------------------
Rick, thanks for reviewing the patch. It appears that my logic of determining
whether we are inside UPDATE/DELETE etc statement is not as full-proof as I
thought. I will look further into it.
As for the permission available through role rather than direct direct tests, I
will attempt to add a standalong test fixture in
RolesConferredPrivilegesTest.java The existing test fixtures are very
sophisticated for what I need to test. If anyone has ideas on how I can use the
existing test fixture in RolesConferredPrivilegesTest.java to add a test case
like
select t1.c1 from user1.t1, user1.t2
Otherwise, I will just add a new test fixture to test above.
