> Key: DERBY-4595
> URL: https://issues.apache.org/jira/browse/DERBY-4595
> Project: Derby
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 10.5.3.0
> Environment: Ubuntu 9.10, Sun Java 6 update 18
> Reporter: Witold Szczerba
> Priority: Critical
> Labels: derby_triage10_10, plan, query

> I was describing everything here and when trying to submit - everything was
> lost, because the session ended and there was no way of going back, so I will
> just point to derby-user mailing list, everything is there, just follow the
> thread:
> http://mail-archives.apache.org/mod_mbox/db-derby-user/201003.mbox/%[email protected]%3E
> or there:
> http://thread.gmane.org/gmane.comp.apache.db.derby.user/12394
> The bottom line is - I had to change application to avoid the query, it is so
> slow (around one hour on production) and there is no workaround.
