> The rpad function - rpad(str1, length [, str2]) returns different result
> compared to postgres, oracle and mysql when length is less than the lenght of
> str1. For example:
> select * from voter where voter_id=10;
> voter_id | name | age | registration | contributions | voterzone |
> create_time
> --------+---------------+-----+--------------+---------------+-----------+---------------------
> 10 | tom underhill | 75 | socialist | 525.33 | 18592 |
> 2015-01-24 07:27:05
> 0: jdbc:drill:schema=dfs> select rpad(name, 8, 'A') from voter where
> voter_id=10;
> +------------+
> | EXPR$0 |
> +------------+
> | nderhill |
> +------------+
> The above result from drill truncates the name from right to left. For the
> other rdbms:
> SQL> select rpad(name, 8, 'A') from voter where voter_id=10;
> RPAD(NAM
> --------
> tom unde
> Looks like truncation occurs from left to right eventhough it's rpad.
