RE: When should one use SQL/RPG?

Not that I've done it with Oracle, however on the iSeries you have the 
command WRKRBDDIRE you should look at.  And then within your program you'd 
have sql's CONNECT TO statement.

Is it possible to retrieve data from an Oracle server into an RPG-ILE 
program using embedded SQL statements?  I have used stand alone statements 
to update information on another AS/400.

Matt,

This is my understanding also.  Rob's post made me wonder if they had 
found
that not to be the case.  I hadn't thought about the remote access angle
though.

Rick,

For a single record, SQL is less efficient than RPG since much of the same
work (mostly running through the query optimizer) has to be done for both
single record and multi-record result sets. Where SQL shines (as long as 
the
files are properly indexed) is in doing bulk operations (like updating
multiple records). SQL is also very good (and much faster than DDM files)
when you are accessing data on remote systems.

Matt
