Re: Censoring SQL access -- ideas?

Sure it can be done with SQL.  You set up an RDB entry pointing to the 
other system and use CONNECT to access the data on the remote system.

Thanks,

Yeah, I've been reading about that.  It has its limitations as well; as 
far as I can tell you're stuck with the layout of the underlying table. 
One of the primary benefits of the view is to select and omit columns, 
and the INDEX ... WHERE doesn't give you that.  Logical files still do 
the combined sort, select and reformat better than any one tool in the 
SQL toolkit.

One other thing - you can't do SQL on a DDM file.  There are 
circumstances where getting at a table on another i is required.  With 
RLA, it's CRTDDMF and I'm done.  With SQL, it's impossible.  (Yes, it 
can be done with ODBC/JDBC, but not with standard SQL.)
