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

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,
Daniel

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.

Perhaps someone created a temporary file to mimic the OPNQRYF just to get
the program to compile originally?

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
