Rick Hillegas commented on DERBY-4397:
--------------------------------------
Thanks for the great spec, Dag. Other than some very minor typos, I have only
one comment, related to Knut's observation above under (2):
It would be good to know, either way, whether this work will affect DERBY-4. If
this does enable INSERT ... SELECT ... ORDER BY, then it would be good to
mention this somewhere in the user guides.
Thanks,
-Rick

> SQL 2008 allows ORDER BY to be specified in subqueries. In conjunction with
> OFFSET/FETCH and/or ROW_NUMBER
> meaningful subqueries with row ordering may be formulated. Cf. MySQL's LIMIT
> may be used in subqueries as well.
> Note that OFFSET/FETCH is currently not allowed in subqueries, either.
