index for:
SELECT MIN(tran_dt)
FROM ach_tran
WHERE cnfr_no = :b1
I'd like the index to include columns cnfr_no and tran_dt (in that order).
The examples I've seen are
just single-column indexes. Is it possible to have this additional
column in a function-based index that
is not involved in the actual function? If yes, what would the index
creation statement look like?
This is version 9.2.0.1 on Sun Solaris 2.6.
Thanks in advance for any assistance.
