I need a keyed LF that can be used in RPG RLA, QRY/400, and SQL. If I use a SQL view, I'm afraid I'll lose my keyed sequence.
Does that mean I have to use a DDS LF?

Subject: RE: Alt index to SQL keyed view
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.
