Re: SQL and defining data structures

... create view is your friend. You must not reference any file in your
programms anyway, never ever.

I agree that create view is your friend in this case because the original
post indicated that the SQL select statement produced a join of several
files. The OP could reference the view as follows:

dcl-ds dsMYVIEW extname('MYVIEW') qualified end-ds;

But in regard to "never ever" referencing files in programs, why would you
say that? Are you suggesting that ONLY SQL views should be referenced in
programs? That wouldn't make a much sense to me.
