Jinfeng Ni created CALCITE-757:
----------------------------------
Summary: View of view is not expanded properly in PlannerImpl.
Key: CALCITE-757
URL: https://issues.apache.org/jira/browse/CALCITE-757
Project: Calcite
Issue Type: Bug
Reporter: Jinfeng Ni
Assignee: Julian Hyde
In PlannerImpl:ViewExpanderImpl, the code does not pass in ViewExpalnderImpl.
That cause a view of another view will not be expanded properly.
Also, ViewExpanderImpl's SqlToRelConverter does not have the same setting, or
does not go throw the same transformation (flattenTypes, decorrelateQuery) step
as the regular one in convert() method. That means some transformation might
be missing to be applied to RelNode generated from a view.
