RE: Re[2]: Question using jdbc/jt400

From: Carl

Wouldn't using ResultSet#previous() accomplish the same thing as a READP?

Not if you go before the first record in the result set. With a logical
file, you can position by key and then do a read previous.

Though i'm really not sure why you would want to use this idiom in
sql. I think the
need for SETGT/READP arose from the inability to dynamically sort records
in RPG.

It's the fastest way to get the last record in a set without having to have
indexes in both directions.
