[ http://issues.apache.org/jira/browse/DERBY-1489?page=all ]
Bryan Pendleton resolved DERBY-1489.
------------------------------------
Fix Version/s: 10.3.0.0
Resolution: Fixed
Derby Info: (was: [Patch Available])
Thanks very much to all the reviewers, and particularly to Mamta who checked
several versions of this patch.
I've committed the _v8_ version of the patch to subversion as revision 453420.
I'm marking this issue resolved; for now, we have an undocumented new feature
which does not work with sqlAuthorization mode. I hope to find time soon to
work on the two followon issues: DERBY-1909 to fix the sqlAuthorization
problem, and DERBY-1926 to provide documentation.
