You cannot access an SQL Index with SQL. You only can access views. It it
the query optimizer which decides if or whether and which indexes are used.
If you created an index with enhanced indexing technologies (such as
additionally generated key fields or where conditions) and you want to
access these data, you either have to build the additional fields you need
in the SELECT statement and/or add the where conditions to the SELECT
statement.
Much better however is to create a view with the appropriate information
(additional key fields and where conditions) and access the view.

Subject: Alt index to SQL keyed view

I'm doing some legacy work and I need to replace an alternate index file.
I'm trying to use a SQL keyed view
(https://developer.ibm.com/articles/i-sql-indexs-and-native-io/). It works
fine in RPG record-level access, but SQL gives SQLSTATE 42851 (A referenced
file is not a table, view, or physical file) and QRY/400 gives CPD4360
(Queried file &1 in &2 not data base file or is an SQL derived key index).

Is there a way around this, or do I have to create a DDS LF?

TIA
