Subject [jira] Commented: (HIVE-655) Add support for user defined table generating functions
Date Sat, 14 Nov 2009 07:30:39 GMT

    [ https://issues.apache.org/jira/browse/HIVE-655?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12777834#action_12777834

Ning Zhang commented on HIVE-655:
---------------------------------

I think it is fine to allow both formats. The select explode could be a shortcut to the lateral
view format. This may help users who are familiar with the TRANSFORM syntax.

> 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.
