Andries Engelbrecht commented on DRILL-3510:
--------------------------------------------
Will this be part of Drill 1.2?
Also if ANSI_QUOTES flag is set, will the back tick ` identifier still work?
The challenge is that in environments where multiple users access a Drill
cluster they may be using different tools and queries. Some may now use back
tick and some double quote identifiers.
Will it be feasible for the SQL Parser to support both at the same time? Then
allowing the JDBC to return the default ANSI standard as identifier.
> Add ANSI_QUOTES option so that Drill's SQL Parser will recognize ANSI_SQL
> identifiers

> 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';
