Will this change an explain plan as well? I'd test it but don't have access
to oracle right now.

The magic phrase is 'NOSEGMENT'.
But, if you're on 9.2.0.x and x < 8, don't create a bitmap nosegment index,
or you won't be able to drop it. ;-)
(Just hit that bug, and applied the 9.2.0.8 patch yesterday to fix the
problem.)

Does someone here recall the syntax for creating metadata only indexes?
This for use by the SQL tuning advisors, etc.
I can't recall the syntax, and cannot find it.
Thanks,
