Daniel John Debrunner commented on DERBY-610:
---------------------------------------------

I think the current behaviour is correct. After a commit the result set is open 
but is not positioned on a row. The result set must be re-positioned with a 
next() or  other method before acessing a row or modifying it with a positioned 
update or delete. I think this may be from the SQL standard, or is it the JDBC 
standard?

The bug 4515 (Cloudscape bug tracking system) was fixed, I think to return the 
correct error as you are seeing.

> After commit, holdable result set cursor used in positioned update can't

> Using the embedded driver, with autocommit off, and holdability for a
> updatable result set  (HOLD_CURSORS_OVER_COMMIT), I first
> position on a row in the result set, and then commit the
> transaction. The result set should still be open since holdability is
> active.  However, when accessing the result set using a named cursor
> in a subsequent "Positioned update" statement, Derby returns an error
> message: "Invalid cursor state - no current row" (SQLState 24000).
> Please see the self-contained repro case in the attachment for
> details.
> It appears the problem is related to reopening of holdable result sets
> after a commit. During normal use of result sets, the ResultSet#next()
> operation will make sure the result set is opened (after locks were
> released at commit time). Apparently no such reopening is performed in
> the "positioned update" case. (small detail: Note that in the
> "positioned update" case, the reopening is for accessing the current
> row (again), not the next - I am not sure if that matters, though).
