Date Wed, 12 Jul 2017 08:17:00 GMT

    [ https://issues.apache.org/jira/browse/FLINK-7160?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16083629#comment-16083629

Fabian Hueske commented on FLINK-7160:
--------------------------------------

There are a couple of Hive UDF related issues already collected in FLINK-5802.
Can you check if this issue is a duplicate of one of those, for example FLINK-5834 requests
support for Hive UDTFs.

Please close this issue if it is a duplicate.
Thank youl

>                 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]
