Timo Walther commented on FLINK-22804:
--------------------------------------
Hi [~yulei0824], a view is always backed by a query. And a query has no
computed or metadata columns anymore but only physical columns. What you are
looking for is some utility that tracks the view columns to their origin but
this can be quite difficult for complex queries. I will close this issue for
now.
> "CREATE VIEW" statement loses computed columns, metadata columns, watermark
> and table constraint
