> cast(parm1 as varchar(n)) should return a string with up to n characters.
> However, currently Drill will ignore the length parameter. For example,
> select first_name, cast(first_name as varchar(2)) from cp.`employee.json`
> limit 2;
> +------------+------------+
> | first_name | EXPR$1 |
> +------------+------------+
> | Sheri | Sheri |
> | Derrick | Derrick |
> +------------+------------+
> 2 rows selected (0.285 seconds)
> In comparison, here is the result run on postgres.
> select cast('abcdef' as varchar(2)) from t1 limit 1;
> varchar
> ---------
> ab
> (1 row)
