You can always write:

CREATE VIEW cte_view AS
WITH cte AS (...)
SELECT * FROM cte;

And then incorporate that into any queries that require the results of said CTE.


Is there any advantage to still using a CTE inside the view definition, and then selecting it?  Instead of just

CREATE VIEW cte_view AS
(...);

Just curious, in case I'm missing something!

Cheers,
Ken
