Paul,
Flattery gets you everywhere!
I didn't find time to complete the write-up, so today's blog note is just a
quick SQL*Plus tip, but I should finish the costing thing over the weekend and
publish Monday.
Regards
Jonathan Lewis

I think you'll also find that the emplid is declared not null.
I've done a little experimental work - the oddity of costing is all about
the LOBINDEX. I'll > be writing a blog note about it tomorrow.
