Subject [jira] Updated: (DERBY-2998) Add support for ROW_NUMBER() window function
Date Tue, 26 Feb 2008 16:04:51 GMT

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

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

    Attachment: d2998-17.stat
                d2998-17.diff

The culprit turned out to be ResultColumnList.allExpressionsAreColumns().

After adding an explict check for any window functions here, we avoid massing up the correlation
flag and every thing seems to be working as expected.
