No, that's a mistake. I meant positioned updates through cursor, I
will check how this mistake could have happened.

They (updatable result sets) can be implemented for a limited set of
cases by constructing appropriate UPDATE statement with RDB$DB_KEY in
WHERE clause (and query rewriting, of course). I do not view this
feature worth the efforts needed, but I will be happy to include this
feature if somebody else implements it. Also, if server provides a way
to either obtain RDB$DB_KEY without need to rewrite original query,
implementing the feature would be almost trivial task.

Sorry for confusion.

Thanks!
