Re: Get PF for LF

In general, this may work most of the time, because the common practice
when creating LF's is to provide only the PF's record name, so the LF
compiler will include all fields. I work with some LF's where the fields
may be renamed, and moreover, not all of them may be selected, and that is
a valid LF. So in these cases, you may not be successful in retrieving the
whole, original PF layout.

Hi Troy


I don't see DSPFLD on a machine I have full authority on. I had
recommended DSPFD below - is that what you meant?


If not, I'm curious to know what DSPFLD is and where it comes from - TAA
Tools, perhaps?

I'm also curious - does the tool you speak of tell you which tables an LF
is based on? DSPFLD sounds like DSPFFD, I also googled for DSPFLD and found
a 30-year-old QMQRY thing, as well as a toolset called Projex4i and some
other stuff - had never heard of Projex4i, anyone know it? Also something
suggested by Nick Litten based on the QADB* tables - I have to give the
same caveat - IBM locks those down pretty well. I just did a little test,
first on a machine where my USRCLS is *SECOFR - I can do anything, of
course. Then on our company system - DSPPFM QADBXREF gave me a not
authorized message. So did trying to take the SQL statement that SYSTABLES
is - over QADBXREF and another QADB* table - and rightfully so.


Many in these lists have elevated authority - be careful about
recommending things you can just do - same challenge if you're a software
developer and test everything with your special profile, not what a
customer will be using.

Vern

Hi Justin


The QADB* PFs and LFs are severely restricted - IBM do not want them
accidentally corrupted. If you are able to work with them, you would seem
to have some elevated level of authority to them. I think it is strongly
advised not to use them in programs that regular users will be running

The JSON in the recent SYSFILES can be used nicely by using the JSON_TABLE
function, I would think. But if you are on pre-7.5 release, I recommend the
DSPFD thing - it's been around forever, safe, reliable. And you can't trust
that IBM won't put tighter reins on these "system" files.


The reason I know is related to a tool I once wrote that used the QADB*
files and failed when lower authority levels tried to run things.


Cheers
Vern

Both QSYS2.SYSFILES and QSYS.QADBLDEP give the answer, but SYSFILES
returns it as JSON. I prefer not to parse JSON if I don't have to.

Thanks guys!
