Subject [jira] Resolved: (DERBY-4043) NullPointerException executing DELETE against table involved in DELETE CASCADE referential constraint
Date Fri, 10 Apr 2009 13:38:14 GMT

     [ https://issues.apache.org/jira/browse/DERBY-4043?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Knut Anders Hatlen resolved DERBY-4043.
---------------------------------------

    Resolution: Duplicate

I am not able to reproduce this issue after DERBY-2353 was fixed, so I'm marking it as a duplicate.

>                 Key: DERBY-4043
>                 URL: https://issues.apache.org/jira/browse/DERBY-4043
>             Project: Derby
>          Issue Type: Bug
>          Components: SQL
>    Affects Versions: 10.4.2.0
>         Environment: Windows XP
> Use encrypted, soft-upgraded DB (from v10.3.2.1)
>            Reporter: Chip Hartney
>
> I am incurring a NullPointerException in the DELETE CASCADE logic of v10.4.2.0.  After
the error, the connection is lost.
> The following is reproducible in my env in which I have a DB created under v10.3.2.1
being accessed through IJ using the v10.4.2.0 libraries.  (I have not tested against other
scenarios.)  Note, however, that variations on this sequence do not recreate the problem...such
as leaving off the PK constraints or adding data to the tables before creating the constraints
or leaving out the "Entry" record.
