Subject [jira] Commented: (DERBY-4071) AssertFailure when selecting rows from a table with CHARACTER and VARCHAR columns
Date Wed, 11 Mar 2009 00:44:50 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4071?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12680710#action_12680710
] 

Dag H. Wanvik commented on DERBY-4071:
--------------------------------------

I have read through DERBY-3880 and also DERBY-3094 and managed to convince myself
that the current issue is related but separate, for what it's worth. Thanks for the suggestion,
Bryan.
I wish I had read both those issues (nice write-ups!) better before undertaking this one :)
