John Sichi commented on HIVE-1558:
----------------------------------

SQL standard has the VALUES clause, so you can do

INSERT INTO t VALUES(3, 'hi');  -- inserts one row

INSERT INTO t VALUES (3, 'hi'), (4, 'bye');  -- inserts two rows

and

SELECT * FROM (VALUES(3, 'hi'), (4, 'bye'))  -- inline table results

If we add dual, it would also be nice to support at least the standard INSERT syntax since that has been around forever.

> The "dual" table in MySQL and Oracle is very convenient in testing UDFs or constructing rows without reading any other tables. 
> If dual is the only data source we could leverage the local mode execution.
