             Summary: Implicit cast in filters fails if enclosed literal has trailing spaces
                 Key: DRILL-2747
                 URL: https://issues.apache.org/jira/browse/DRILL-2747
             Project: Apache Drill
          Issue Type: Bug
          Components: Query Planning & Optimization
            Reporter: Abhishek Girish
            Assignee: Jinfeng Ni


Implicit cast in filters fail if literals contain trailing spaces. 

*Drill:*
{code:sql}
> select d_date_sk, d_day_name from date_dim where d_date is not null and d_date between
'1900-01-10' and ' 1900-01-20'  limit 1 ;
+------------+------------+
| d_date_sk  | d_day_name |
+------------+------------+
+------------+------------+
No rows selected (0.221 seconds)
{code}

Prefixing the literal with "date" happens to solve the issue:
{code:sql}
> select d_date_sk, d_day_name from date_dim where d_date is not null and d_date between
date '1900-01-10' and date ' 1900-01-20'  limit 1 ;
+------------+------------+
| d_date_sk  | d_day_name |
+------------+------------+
| 2415030    | Tuesday    |
+------------+------------+
1 row selected (0.128 seconds)
{code}

*Postgres:*
{code:sql}
# select d_date_sk, d_day_name from date_dim where d_date is not null and d_date between '1900-01-10'
and ' 1900-01-20'  limit 1 ;
 d_date_sk | d_day_name
-----------+------------
   2415030 | Tuesday
(1 row)
{code}
