> 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}
