Knut Anders Hatlen commented on DERBY-4045:
-------------------------------------------
Kim, I think the doc will have to be changed anyway, since a fix of the SQL
will probably not allow all kinds of subqueries in WHERE clauses. So for now it
would be fine to update the doc with a bullet saying what you suggested above.
If we change the SQL later, the sentence could be changed to specify which
kinds of subqueries we don't allow. We could perhaps change the documentation
in a separate issue and leave this one open to track the request for the SQL
change.
