Julian Hyde commented on BEAM-301:
----------------------------------

Yes. And "last year" is a rolling total based on the time each order was placed, not the time
the query was started.

> The SQL DSL helps developers to build a Beam pipeline from SQL statement in String directly.

> In Phase I, it starts to support INSERT/SELECT queries with FILTERs, one example SQL
as below:
> {code}
> INSERT INTO `SUB_USEREVENT` (`SITEID`, `PAGEID`, `PAGENAME`, `EVENTTIMESTAMP`)
> (SELECT STREAM `USEREVENT`.`SITEID`, `USEREVENT`.`PAGEID`, `USEREVENT`.`PAGENAME`, `USEREVENT`.`EVENTTIMESTAMP`
> FROM `USEREVENT` AS `USEREVENT`
> WHERE `USEREVENT`.`SITEID` > 10)
> {code}
> A design doc is available at https://docs.google.com/document/d/1Uc5xYTpO9qsLXtT38OfuoqSLimH_0a1Bz5BsCROMzCU/edit?usp=sharing.
