        The Access plan is kinda like the optimizer's best guess as to how
to get the data .

        Try these;

        1. On an Embedded SQL program,  use the command PRTSQLINF and see
what you get.
        2. Do a start debug (no program name) and run the embedded SQL
program and look at 
        your job log for neat info.   Read the second level text on the job
log messages.

        Subject:        Query (QQQQUERY) analysis logging

        Hello all, 

        Could someone refresh my memory?  When I run anything that uses
QQQQUERY (Sequel's, OPNQRYF, IBM query, etc), I have seen, and would like to
see again, a 'log' the system creates saying things like "An access path was
built over FILEA using FIELDA.  To eliminate the access path build, create a
logical over FILEA by FIELDA".  The wording was something like that.  I
think I remember the words "access plan" or "build plan" relating to this. 
Anyone have any idea what I'm talking about ?



        Thanks
