Subject [jira] Updated: (DERBY-4245) Sorting a table containing a CLOB fails after upgrade to 10.5
Date Wed, 10 Jun 2009 16:02:07 GMT

     [ https://issues.apache.org/jira/browse/DERBY-4245?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Kristian Waagan updated DERBY-4245:

    Attachment: derby-4245-2a-sqlclob_fix.diff

It makes sense, as it makes the code cleaner. Is patch 1b along the lines you were thinking

I also attached patch 2a, which fixes the problems in SQLClob. When applying it, the bug should
no longer reproduce with a clean database. The bug will still occur with upgraded databases.
Patch 2a passes the regression tests.

Patches ready for review.
