Bill was eliminating DDM. Instead, use DRDA to connect to the remote
database and read the data (that the DDM was pointing to) directly.

Probably, otherwise I'm very confused.

But the problem remains - how to combine, or whether to try to combine,
DDM access to remote data and SQL. Actually, I'm told, DRDA, which is
the mechanism for remote data access with SQL, is built on (or is the
foundation of) DDM - I hear both stories. At any rate, they are closely
related. But SQL doesn't allow the use of DDM files, period.

Hope we hear more from Bill!

Hi Bill

Can you explain this more? As far as I know, a DDM file is local and
points to a file on a remote system. And doesn't have source.

So I'd like to learn what you refer to, as it might be useful.

Subject: Using STRSQL against a DDM file

Morning all
On one system (system A), I have a DDM file connecting to another
(system B)
I have to pull data from this DDM file on system A, but when
this in STRSQL, I get the message
File not table, view, or physical file.
Which is true
I have attempted to use an OVRDBF with the same result
I have used CPYF and copied this DDM file to another file and was
to use this CPYF file, but I was wondering if anyone had found a way
use SQL against a DDM file?
As always, all responses MUCH appreciated
