Jinfeng Ni updated DRILL-2747:
------------------------------
Assignee: Mehant Baid (was: Jinfeng Ni)
> Implicit cast in filters fails if enclosed literal has leading or trailing
> spaces
> ---------------------------------------------------------------------------------
>
> Key: DRILL-2747
> URL: https://issues.apache.org/jira/browse/DRILL-2747
> Project: Apache Drill
> Issue Type: Bug
> Components: SQL Parser
> Reporter: Abhishek Girish
> Assignee: Mehant Baid
> Fix For: 1.2.0
>
>
> Implicit cast in filters do not return results if literals contain leading or
> 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}
> Update:
> In case of String literals with numeric value, leading or trailing spaces
> causes the query to fail with NumberFormatException:
> *Drill:*
> {code:sql}
> > select d_date_sk, d_day_name from date_dim where d_week_seq in ('1','2','3
> > ') order by d_week_seq limit 3;
> Query failed: RemoteRpcException: Failure while running fragment., 3 [
