The index is easy. But if this is a unique access to very few programs,
another option is using dynamic SQL to create a cursor with the selection
criteria and order by you require. If you have never used one, you can
update within the cursor and it saves having a permanent index on the
table. Just another option since you stated you were trying to move to
SQL. :)

If you want a keyed access with native I/O you need to create an index!
BTW SQL Indexes can not be specified in an SQL Statement, but they can be
used in composition with native I/O like any keyed DDS described logical
file.

... and SQL is much more powerful and much easier than DDS
... and DDS is stabilized and outdated

Subject: SQL Equivalent of CRTLF

I've been using SQL I programs and to create views for quite some time.
I'm
trying to force myself away from DDS.

So I created a new table with SQL... now I need to create a subset of that
table by way of a logical file (I want to use RPG Native access in my
program), which can also be updated.

Is there a simple way to create a view of my table that contains all
columns
"where" one of the columns is blank?

My current take on DDL versus DDS is that DDS is much, much easier and
faster to use.
