Subject:        RE: SQL for top 100 values

I tried to run it in Oracle 7.3.4, it comes up with a syntax error

Here is the SQL

    select x.fein,x.open_bal
    from (select sf_get_fein(employer_id) fein, nvl(total_open_balance_amt,0) open_bal

          from employer
          order by open_bal desc ) x

    where rownum < 101

Here is what I get

SQLWKS>     select x.fein,x.open_bal
     2>     from (select sf_get_fein(employer_id) fein,
nvl(total_open_balance_amt,0) open_bal
     3>           from employer
     4>           order by open_bal desc ) x
     5>     where rownum < 101
     6>
          order by open_bal desc ) x
          *

ORA-00907: missing right parenthesis

Is it because I am on a lower version

Thanks
Deen

rownum < 101 is OK if you nest your query, ORDER BY included, as an in-line view,
ie

    select x.val
    from (select val

          from my_table
          order by val desc) x

    where rownum < 101
