> I defined the following view:
> {code:sql}
> create view v1 as
> WITH mycte as (SELECT 1 as col1) SELECT col1 FROM mycte;
> {code}
> If I run this query:
> {code:sql}
> WITH mycte as (SELECT * FROM views.v1) SELECT * from mycte ;
> {code}
> it fails on generate the query plan with this exception:
> {code}
> TEIID31124 Recursive plan detected.  Command type Query was already issued against mycte.  Planning cycle: [Query mycte, Query views.v1]
> {code}
> Using /*+ no_inline */ hint to prevent the inlining doesn't fail and returns the correct result.
