Hi,
Calcite is capable of handling a simple column alias query such as
SELECT city as c
FROM (values('PARIS')) as t(city)
However, I add a simple predicate
SELECT city as c
FROM (values('PARIS')) as t(city)
WHERE c is not null
the query fails in validation indicating "Column 'C' not found in any table”
Caused by: org.apache.calcite.runtime.CalciteContextException: At line 1,

I’m curious if this is the intended Calcite behavior?
This looks might be related to
https://issues.apache.org/jira/browse/CALCITE-4305, but I am not sure.
Thanks,
