>                 Key: FLINK-7160
>                 URL: https://issues.apache.org/jira/browse/FLINK-7160
>             Project: Flink
>          Issue Type: New Feature
>          Components: Table API & SQL
>    Affects Versions: 1.3.1
>            Reporter: Sihua Zhou
>
> Support one row in and multi-column/multi-row out(one-to-many mapping), just like udtf in hive.
> The query would like this:
> {code}
> select udtf(arg1, arg2) as (seg1, seg2, seg3) from table
> {code}
> This is to be friendly for the user that migrate from hive. At present, calcite doesn't support this grammar, but it will be support it later, link: [CALCITE-1581|https://issues.apache.org/jira/browse/CALCITE-1581]
