    @laurentgo Since you have already reviewed it, could you please take a look at this updated
PR. There is only one commit now, because current PR differs very much from the previous one.
Anyway I was replied into your previous comments.

> Currently Drill's SQL parser uses backtick as identifier quotes, the same as what MySQL
does. However, this is different from ANSI SQL specification, where double quote is used as
identifier quotes.  
> MySQL has an option "ANSI_QUOTES", which could be switched on/off by user. Drill should
follow the same way, so that Drill users do not have to rewrite their existing queries, if
their queries use double quotes. 
> {code}
> SET sql_mode='ANSI_QUOTES';
> {code}
