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.
> Add support for ROW_NUMBER() window function
