Project: Calcite
Issue Type: New Feature
Reporter: Xiaoyong Deng

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
func(c0, c1) as (f0, f1, f2)
from table_name;
{code}
c0 and c1 are 'table_name' columns. f0, f1 and f2 are new generated columns.
