If you're running Oracle8i,
you can do this:
SELECT *
FROM (SELECT * FROM my_table ORDER BY col_name_1 DESC)
WHERE ROWNUM < 10;

Use this workaround with prior releases: SELECT *
FROM my_table a
WHERE 10 >= (SELECT COUNT(DISTINCT maxcol)

              FROM my_table b
              WHERE b.maxcol >= a.maxcol)
             ORDER BY maxcol DESC

;

Hope this helps!
