Bryan Pendleton updated DERBY-2887:
-----------------------------------
Attachment: prototypeCodeNoTests_v3.diff
Attached is prototypeCodeNoTests_v3.diff, updated in response to the various
suggestions.
This version 3 patch is much simpler than the previous two; Dan's ideas about
sharing common code into DataType.java were a big win.
My next steps will be to: add some new tests, investigate the sort avoidance
issue, and track down a diff in the Wisconsin tests involving outer joins. All
the other existing tests pass.

> <null ordering> ::=
> NULLS FIRST
> | NULLS LAST
