Subject [jira] Updated: (DERBY-2998) Add support for ROW_NUMBER() window function
Date Tue, 29 Jan 2008 12:04:34 GMT

     [ https://issues.apache.org/jira/browse/DERBY-2998?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Thomas Nielsen updated DERBY-2998:
----------------------------------

    Attachment: d2998-9-derby.log
                d2998-9.stat
                d2998-9.diff

Attaching minor updates according to Ricks comment in d2998-9.diff.

The query/executable plan is attached in d2998-9-derby.log, with d2998-9.diff applied, executing:
   select * from (select row_number() over () as r, t.* from t) as tr;

The 9 patch attached does not evaluate WHERE clauses on expression columns in the materialized
subquery resultset correctly.
