Mike Matrigali updated DERBY-3456: ---------------------------------- Description: Enable alter table to change a column that participates in a unique constraint to allow nulls. I have committed the derby-3456-Tests_v2.diff and derby-3456v5.diff patches. I believe these are the only outstanding patches for this issue. I did a review of the changes, and ran complete set of tests against ibm15 jvm. Thanks to army for providing the initial reviews that led to the complete patch. > Allow removing not null from collumns particpating in unique constraint. > ------------------------------------------------------------------------ > > Key: DERBY-3456 > URL: https://issues.apache.org/jira/browse/DERBY-3456 > Project: Derby > Issue Type: Sub-task > Components: SQL, Store > Affects Versions: 10.4.0.0 > Environment: all > Reporter: Anurag Shekhar > Assignee: Anurag Shekhar > Attachments: altertable.diff, derby-3456-Tests.diff, > derby-3456-Tests_v2.diff, derby-3456v1.diff, derby-3456v2.diff, > derby-3456v3.diff, derby-3456v4.diff, derby-3456v5.diff, setnulltest.diff, > upgradetests.diff, upgradetests_v2.diff > > > Enable alter table to change a column that participates in a unique > constraint to allow nulls. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
