Subject [jira] Commented: (DERBY-4204) Runtime statistics not collected on re-execution of statement
Date Wed, 13 May 2009 10:59:45 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4204?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12708882#action_12708882
] 

Knut Anders Hatlen commented on DERBY-4204:
-------------------------------------------

Committed the patch to trunk with revision 774281.

Bryan, it should be OK to add a regression test based on XPLAIN to trunk now, either as part
of this issue or as a separate issue.

I'll leave this issue open until the fix has been backported.

> Runtime statistics are only collected the first time an insert/update/delete statement
is executed. The behaviour changed between Derby 10.2.2.0 and Derby 10.3.1.4, so this was
likely introduced by DERBY-827.
