Subject [jira] Commented: (DERBY-396) Support for ALTER STATEMENT to DROP , MODIFY, RENAME a COLUMN
Date Sat, 08 Jul 2006 16:10:35 GMT
    [ http://issues.apache.org/jira/browse/DERBY-396?page=comments#action_12419866 ] 

Bryan Pendleton commented on DERBY-396:
---------------------------------------

I propose to file separate JIRA issues for the topics described here:

1) drop column
2) rename column
3) change column from null to not null, or vice versa
4) change column default value
5) change column datatype

DERBY-119 already exists to track issue (3); I will be filing 4 new issues, linked to this
one, to track the other topics. DERBY-168 was previously filed for issue (4), but was closed
by changing the documentation, so I will open a new issue to track addition of the functionality.
