[jira] [Created] (FLINK-3087) Table API do not support multi count in aggregation.

Chengxiang Li created FLINK-3087:
------------------------------------

             Summary: Table API do not support multi count in aggregation.
                 Key: FLINK-3087
                 URL: https://issues.apache.org/jira/browse/FLINK-3087
             Project: Flink
          Issue Type: Bug
          Components: Table API
    Affects Versions: 0.10.0
            Reporter: Chengxiang Li
            Assignee: Chengxiang Li


Multi {{count}} in aggregation is not supported, for example:
{code:java}
table.select("a.count", "b.count")
{code}
It's valid in grammar, besides, {{a.count}} and {{b.count}} may have different values actually if NULL value handling is enabled.
