Reverse key index won't help you in ORDER BY DESC, will it?

AFAIK Reverse-key index will store 'Naveen' as 'neevaN' and 'Rich' as 'hciR' and so won't be helpful in ORDER BY DESC

Hey,

Anyone have any advice on indexing SYS tables? Specifically, I've been experimenting with putting a reverse index on the TIMESTAMP# column of AUD$, since almost all of my queries against the AUD$ views end with "ORDER BY TIMESTAMP DESC". In 8.1.7.4.0 test DBs on HP/UX, the index -- created under a non-SYS DBA schema -- works great. I'm looking for pitfalls, but can't come up with any of my own...

TIA!
Rich
