Thank you Tom, it works.

I agree with you that the doc could/should be fixed/enhanced, because the
explanation of "name" is immediately following the snippet you cited, and it
says "The name (optionally schema-qualified) of a view to be created": it
would never occurred to me that I could use a not-qualified name within the
view.
