Subject [jira] Commented: (DERBY-4071) AssertFailure when selecting rows from a table with CHARACTER and VARCHAR columns
Date Wed, 25 Feb 2009 18:45:01 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4071?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12676736#action_12676736
] 

Aaron Digulla commented on DERBY-4071:
--------------------------------------

I mean: Make VCHR the first column and CHR the second. Just download the test case, copy it
into your Derby project and run it. It contains a "good" case and a "bad" case.
