Subject [jira] Assigned: (DERBY-396) Support for ALTER STATEMENT to DROP , MODIFY, RENAME a COLUMN
Date Mon, 03 Jul 2006 23:16:36 GMT

Bryan Pendleton reassigned DERBY-396:
-------------------------------------

    Assign To: Bryan Pendleton

I am interested in working on this issue, and would like to hear from others who are interested
in it.

I propose to start by working on ALTER TABLE DROP [COLUMN] column [CASCADE|RESTRICT].

If that goes well, I'll move on to some of the other ALTER TABLE column variants.

Following the suggestion made by Dan on the mailing list
(http://www.nabble.com/forum/ViewPost.jtp?post=1252308), I'm hoping to wire up the
parser to the existing Alter Table support code.

I've got a prototype implementation of the DROP COLUMN support working, and
will be asking the list for some help with parser issues soon.
