Re: Sorting records in Physical and Logical files

In the DDS? I though the point of a logical file was to build an index that was an alternate to the default sorting sequence of the Physical file (among other things). Yes, I could issue an ORDER BY using SQL or OPNQRYF by I though the file had a "natural" sorting order that was set by the DDS.

So, there is no way to define a physical file using DDS to sort records in anything other than arrival sequence?

I thought I understood this but apparently I don't.

I have a physical and logical file with the following specs:

UNIQUE
R FASA809 TEXT('List Workfile')
-------------------------------------------------------
record layout here:
SLWID 6S 0 COLHDG('Absence ID')
SLW# 6S 0 COLHDG('Seq. Number')
SLWSN 9S 0 COLHDG('Sub SSN')

K SLWID
K SLW#

The logical file looks like:

UNIQUE
R FASA809 PFILE(PASA809)

K SLWID
K SLWSN


The physical file has a randomly generated number in field SLW# and
since the keys are SLWID and then SLW# in that order. I would expect the
file to be ordered that way when I open it up in Query or a simple
select with no ordering in SQL. However, the file is always ordered in
arrival sequence. If I read through this file, I see the records in the
order in which they were written in the file. I *expected* them to be
ordered by the key sequence.

What did I miss or misunderstand?

Thanks
