usually when someone gets persistent with wanting more than theory or copy,
i work out the details and actually test it before i post it here. the only
time i don't test is when i specifically say "this should work, but i
haven't tested it".
as for microsoft's suggestion, i'm sure they would give such advice. though
the above is fully functional, it causes much overhead and doesn't scale
well. the better suggestion, though i didn't demo it here, is to create a
temp table with an additional, autonumbered field. that field would equate
to ROWNUM after inserting your SELECTed data...inclusive of condition
clauses and ordering. but, ms isn't always the best discriminator of
efficiency and effectiveness.
cheers.
