Subject [jira] Updated: (DERBY-3330) provide support for unique constraint over nullable columns
Date Tue, 04 Mar 2008 01:42:50 GMT

     [ https://issues.apache.org/jira/browse/DERBY-3330?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mike Matrigali updated DERBY-3330:
----------------------------------

    Derby Info: [Patch Available, Release Note Needed]  (was: [Release Note Needed, Patch
Available])

I am looking at committing a version of the latest changes, once they pass a set of tests
for me and my final review.  If anyone has any reservations about this going in, let me know.
 Overall I think the changes now only affect only the new 
functionality so even if I find some non-test related problems I am likely to commit to make
it easier to address the remaining issues.
