Subject [jira] [Commented] (DERBY-3002) Add support for GROUP BY ROLLUP
Date Mon, 15 Aug 2011 05:24:27 GMT

    [ https://issues.apache.org/jira/browse/DERBY-3002?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13084968#comment-13084968
] 

Myrna van Lunteren commented on DERBY-3002:
-------------------------------------------

I thought usually we mark 'release note needed' when there's some kind of incompatibility
with previous releases, and I was wondering what the incompatibility was. Maybe the release
note flag was set to explain this was only an initial step in support for ROLLUP style GROUP
BY? Or was there incompatibility because of different performance of certain queries? 

But as I've now marked this as fixed in 10.6.1.0, (which I think is the right value), adding
the release note won't really be of any use in generating any release notes, and I don't think
it belongs in the 10.8 release notes.
