Subject [jira] Commented: (DERBY-4426) With generated columns, INSERT with DEFAULT inside a VALUES clause inside a UNION fails.
Date Sat, 28 Nov 2009 01:19:20 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4426?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12783195#action_12783195
] 

Dag H. Wanvik commented on DERBY-4426:
--------------------------------------

As to your comment, Knut "do you know of a way to devise a test for it
to verify that the changes are correct?", I am not sure that I do,
except for studying the code as to what top level result sets at this
point of processing in an INSERT can have DEFAULT syntactically,
outside subqueries, and adding test cases for those. The catch-all
method in RSN does nothing.
