7.3 does not accept ORDER BY in views (inline or otherwise). There is an
old trick available however :
select sf_get_fein(e1.employer_id) fein,
nvl(e1.total_open_balance_amt,0) open_bal
from employer e1
where 99 <= (select count(*)
from employer e2
where e2.total_open_balance_amt >=
nvl(e1.total_open_balance_amt)
order by 2 desc
Should more or less give you what you want. Add an index on
total_open_balance_amt if you do not want the query to run for hours.
