Daniel Barclay (Drill) commented on DRILL-3510:
-----------------------------------------------
Will the standard-identifier-quotes mode be controllable via a regular session
option that shows up in the options table?
(If so, the JDBC driver can read the value by querying that table, and should
be able do basic caching, reusing a cached value between queries (when, say, a
BI tool might make multiple calls to generate delimited identifiers), and
invaliding the cache when the next SQL statement is executed (because it could
be one that changes the option value).)
> 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';
