[Shang Yuanchun (Jira)]

Haohui Mai created FLINK-6595:
---------------------------------

             Summary: Nested SQL queries do not expose proctime / rowtime attributes
                 Key: FLINK-6595
                 URL: https://issues.apache.org/jira/browse/FLINK-6595
             Project: Flink
          Issue Type: Bug
            Reporter: Haohui Mai
            Assignee: Haohui Mai
             Fix For: 1.3.0


We found out that the group windows cannot be applied with nested queries out-of-the-box:

{noformat}
SELECT * FROM (
  (SELECT ...)
UNION ALL)
  (SELECT ...)
) GROUP BY foo, TUMBLE(proctime, ...)
{noformat}

Flink complains about {{proctime}} is undefined.
