-----------------------------
Adding new token would make changes in many of gold files. I'll update that

> Single sourced multi (insert) query is very useful for various ETL processes
> but it does not allow subqueries included. For example,
> {noformat}
> explain from src
> insert overwrite table x1 select * from (select distinct key,value) b order
> by key
> insert overwrite table x2 select * from (select distinct key,value) c order
> by value;
> {noformat}
