Re: KLIST question

I would use either OPNQRYF in the CL program or embedded SQL in the RPGIV
program, depending on shop standards.  Both methods will create a temporary
access path.  As you point out, another alternative would be to create a
logical file.  If you only use this logical once a day, you might specify
delayed access path maintenance when creating the logical file.  Remember,
if any users run queries selecting records by date, their queries could use
the access path from the logical file.

The only way I know to determine which is a better method is to run STRDBMON
to an outfile and see how many times an access path by date is created.  If
is truly is created only once a day, than I would probably use an OPNQRYF or
embedded SQL.  If the access path is created by users running queries
interactively in addition to the report, I would probably create a logical
file with immediate access path maintenance.

Hope this helps.
