If they are SQL views then yes you can create a view over it
Hmm. But as I just determined empirically, while one can also join to a
DDS join-logical in an SQL ad hoc query, one can't do so in a CREATE VIEW.
And I just realized there's another issue: as I understand it, in SQL,
views and indexes are separate entities. Is there a way to make an SQL
view look like a keyed logical to an RPG program that uses native RLA?
