Re: Compiling RPGLE using non-keyed file that's using OPNQRYF to specify key fields -- RPG400-L

For Opnqryf you don't have to specify the file as keyed, it comes in the
correct order. I've never seen where you CHAIN or READE to a file that's
opened. Use the OPNQRYF to do your order and selection and just read the
file.

Remove the key from the Fspec, does the program fail to compile?

You don't have to do it all at once - simply program by program.

Sooner or later you would have to modernize anyway - so why not start with
"killing OPNQRYF one program after another".

Nice idea, but we have 400+ programs to compile plus other changes to

make.

I would modernize that program and simply use SQL to do that job.

Everything with OVRDBF and OPNQRYF is implicitly unstable in regards to
building the application.

Using SQL and explicitly stating the table columns (fields) or using an
externally described data structure frees you from being dependent on
overrides and run time "query magic".

And - you most probably get an performance boost too, because SQL access
paths are cached by the SQE and partly in the program objects on compile
time or first run.

HTH and kind regards,

On that ONE FILE turn off level check?

There was a time when designers loved OPNQRYF because it gave the SQL

capability without having to do imbedded SQL.

Subject: Compiling RPGLE using non-keyed file that's using OPNQRYF to
specify key fields

Hi, I'm a bit stumped with this one
There's a third party application on our system and we run a process

over

one of their files that's not keyed.
We have a CL that does an OVRDBF and OPNQRYF specifying key fields,

We

then call an RPGLE to process.
The base file has changed so we need to recompile the RPGLE I keep

getting

the following:

Msg id Sv Statement Message text

*RNF7081 30 013500 The File operation is not valid; there are

no

common key
fields. The specification is ignored.

I've tried performing the OVRDBF and OPNQRYF scoped to *JOB and

compiling

interactively but its having none of it.

Had a search and found a page on Code400 stating this is not

possible.

Just confused as to how this program has been running daily for

twenty

years.
Debugged the live program and it's the same and does not report any

issues

Any help on how I can get it compiled would be greatly appreciated

Regards.
Liam
