In Oracle, top-n analysis is accomplished by first ordering the values in an inner sub-query, then selecting the rows from an outer query. You can use DESC in the order by clause to get the last row, rather than the first row. Oracle does not guarantee the row returned until or unless an order by clause has been applied.

SELECT *
FROM   (SELECT   column_names
        FROM     table_name
        ORDER BY column_name DESC)
WHERE  ROWNUM <= 1
