Subject [jira] Commented: (DERBY-1490) Provide ALTER TABLE RENAME COLUMN functionality
Date Sat, 28 Oct 2006 15:04:18 GMT
    [ http://issues.apache.org/jira/browse/DERBY-1490?page=comments#action_12445382 ] 
Bryan Pendleton commented on DERBY-1490:

Thank you Rajesh and Yip and Army. That is very useful feedback.

I think that I shall revise the patch to propose just the RENAME COLUMN statement syntax,
and to take into account the other comments and to update the patch to match current trunk.

I think that it makes sense to file several follow-on issues to track several of the issues
raised by the reviewers. So I'll do that.

Thanks very much !

> Provide a way to rename a column in an existing table. Possible syntax could be:

views, indexes, triggers, etc.
