as an aside....

update ranktest
  set rank = (select max(rank) + 1 from ranktest)
  where dollar = (select max(dollar) from ranktest
    where rank = 0)
    and rank = 0

if you repeatedly execute this, you get the ranking, but you have to repeat
the execution of the statement until no more records are updated.... sqlcode
<> 0
