I dunno, this SQL seems to be faster, on my database anyway:
SELECT EMPLOYEE_ID
FROM (SELECT EMPLOYEE_ID FROM emp ORDER BY EMPLOYEE_ID desc)
WHERE rownum < 2;
I killed the examples after ten minutes of waiting each. My SQL ran in 2-3 minutes (depending on time of day). The table I'm running these on has over 4.5 million records.
