Subject [jira] Commented: (HIVE-655) Add support for user defined table generating functions
Date Fri, 13 Nov 2009 16:27:39 GMT

    [ https://issues.apache.org/jira/browse/HIVE-655?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12777546#action_12777546

Namit Jain commented on HIVE-655:
---------------------------------

I was thinking about it, and there is no workaround for the above operation. So, I am fine
with supporting it.

However, we should throw an error if there is a group by or anything like that.

> Provide a way for users to add a table generating function, i.e., functions that generate
multiple rows from a single input row. Currently, the only way to do it is via the TRANSFORM
clause which requires streaming the data.
