the source for the DTAWHS is this
CREATE TABLE PROJ_MKWN1/DTAWHS (
CUSTOMER# CHAR ( 8),
NAME CHAR (40 ),

STATE CHAR (3 ),

ZIP_CODE char (10 ),

ORDER# CHAR (8 ),

Now we're getting somewhere.

The source you posted above is stored in the source file QDDSSRC in
member DTAWHS. This is probably processed via RUNSQLSTM. The fact that
the member type is TXT is irrelevant to your question because the member
type is only important to SEU, PDM and RDi (editors and compiler front
ends).

here is the official info on this file. Note that in the DDS it is has a
TYPE of TXT, yet, on an Library level view, it has an attribute of PF.

Once someone processed the source (CREATE TABLE), the database manager
created a table - a PF. As you show below, that table is in fact a PF
and it is called DATAWHS.

Now for your question.

The table DATAWHS is not a view, it is a table in SQL parlance, or a PF
to a native OS programmer. It looks as if someone has created at least
one view (or LF) called DATA_WHSV3.

Do you want to access DATA_WHSV3 by a different key? Why? Is it
because there is select/omit criteria? Generally, one would do a CREATE
VIEW over the base PF (table), not over another logical file. If you
already had a VIEW (and I don't see that here), then you'd do a CREATE
INDEX to give the database manager some hints on how to optimise SQL
queries.

Let's assume for the moment that you had a VIEW with a key - how would
you be accessing it? SQL SELECT (including embedded SQL)? Query/400?
ODBC? RPG READE? OPNQRYF?
