Hi Tom Lane,
Thanks for the reply, something doesn't sound right here. How can an
update cause a new record to be created (id = 6) as well as updating the
correct record (id = 3)?
I am not sure what you mean by 'subselect' in the views output list.
Isn't that what I am doing in creating the view?
Regards Neil
