hhhhmmmmmmmmm......

with inRank (cust, doll) as (select customer, dollars from rankingFile order
by dollars desc)
update rankingFile
  set rank  = (select max(rank) + 1 from rankingFile)
  where customer = cust
       and rank = 0

it's just too bad that SQL chokes on this... the 400 won't allow order by on
the common table expression and the 400 won't do the recursion and it won't
allow update from the common table expression.

so the short answer appears to be "no, not with just SQL."
