Subject [jira] Updated: (DERBY-268) Add Support for truncate table
Date Tue, 28 Sep 2010 13:56:33 GMT

     [ https://issues.apache.org/jira/browse/DERBY-268?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Rick Hillegas updated DERBY-268:
--------------------------------

    Attachment: derby-268-03-aa-npe.diff

Attaching derby-268-03-aa-npe.diff. This patch fixes the NPE seen in the TruncatorConcurrency
experiments when the re-initialization statement is TRUNCATE TABLE or DROP TABLE. I am running
regression tests now.

Touches the following files:

----------

M      java/engine/org/apache/derby/impl/store/access/conglomerate/GenericController.java

The NPE occurred while trying to update the statistics for a conglomerate which has been dropped.
The fix is to not update the statistics if the conglomerate no longer exists.

----------

M      java/testing/org/apache/derbyTesting/functionTests/tests/lang/TruncateTableTest.java

Added a test case to track this fix.
