[ https://issues.apache.org/jira/browse/DERBY-6904?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Harshvardhan Gupta updated DERBY-6904:
--------------------------------------
Attachment: 6904_3.diff
I have completed work on the hard upgrade strategy with the attached patch 6904_3.diff. All the test suites now pass with soft upgrades and hard upgrades. I also manually tested the expected behaviour using ij.
I now have to add test cases for the newly added functionality. The patch resolves the following related issues : DERBY-6903, DERBY-6904, DERBY-6905 and DERBY-6906

> It would be nice to have a variant of the ALTER TABLE statement,
> similar to the SET INCREMENT BY or SET RESTART WITH variants,
> that allowed a user to change the CYCLE option on an IDENTITY column.
> I think that the code flow for this could be closely modelled on the
> code flow for the SET INCREMENT BY variant: after the statement
> is parsed, we simply need to drop and recreate the underlying SEQUENCE
> object with the desired CYCLE option (and preserving all the other
> aspects of the underlying SEQUENCE object.
