Re: SQL statement to read previous records

A quick test on 7.1...

I was able to create the index..

Not sure it was used, in VE I see "Values List" instead of the expected
"Radix index probe"...I see "Values List" as the first step with or without
the index.

This is on a table with 1,220,222 records...and I asked for rrn() = 50,000.

Perhaps I'm doing something wrong.

FWiW: Given an INDEX can be created on RRN(), would seem kinda daft that
such a keyed access path (AccPth) [still] could not be used to implement a
query.
