Subject [jira] Commented: (DERBY-4116) SYSCS_UTIL.SYSCS_UPDATE_STATISTICS should update the store estimated row count for the table
Date Wed, 25 Mar 2009 12:46:51 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4116?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12689098#action_12689098

Kathey Marsden commented on DERBY-4116:
---------------------------------------

Thanks Knut, that seemed to do the trick.  I will make a proper patch for the issue and do
testing.  I think I'll keep the index estimatedRowCount update since it does seem to be being
set, just in case someone is using it for something.

>             Project: Derby
>          Issue Type: Bug
>          Components: SQL
>    Affects Versions: 10.5.1.0, 10.6.0.0
>            Reporter: Kathey Marsden
>
> When SYSCS_UTIL.SYSCS_UPDATE_STATISTICS is run, it doesn't update the store estimated
row count.  The program oldSelectivity.java attached to DERBY-3955 shows that the statistics
are not updated.
