> In this query it looks like identifies are case insensitive.
> 0: jdbc:drill:schema=dfs> select Eventdate from `test.json` where eventdate
> is not null;
> +------------+
> | Eventdate |
> +------------+
> | 2014-01-01 |
> | 2014-01-01 |
> | 2014-02-01 |
> +------------+
> 3 rows selected (0.107 seconds)
> However, in subquery, they suddenly change the behavior and become case
> sensitive.
> 0: jdbc:drill:schema=dfs> select EVENTDATE from ( select Eventdate from
> `test.json` where eventdate is not null );
> Query failed: Query failed: Failure validating SQL.
> org.eigenbase.util.EigenbaseContextException: From line 1, column 8 to line
