             Summary: Rework selection when grouping in Table API
                 Key: FLINK-3567
                 URL: https://issues.apache.org/jira/browse/FLINK-3567
             Project: Flink
          Issue Type: Bug
          Components: Table API
            Reporter: Timo Walther


{code}table.groupBy("a").select("e"){code}
does not throw any exception.

Fabian looked at the implementation of GroupedTable.select() and it looks incorrect. It does not group but just add a selection. Either we should reject the select or select the value an arbitrary row of the group.
