Thomas Nielsen updated DERBY-2998:
----------------------------------
Attachment: d2998-12.stat
d2998-12.diff
Attaching 'd2998-12.diff' patch that fixes the problems also seen by Army.
- queries ordered on a column left out of the projection
- incorrect results due to incorrect column mapping
- the assert due to incorrect column mapping
The 16 queries in my previously attached test4 patch run successfully, and the
lang/_Suite runs without failures.
There's still a problem with the column mapping if you do multiple window
functions in a single RCL.
If you happen to play with this and see failing queries, please let me know.
> Add support for ROW_NUMBER() window function
