--------------------------------------

             Summary: Returning NULL instead of array-index-out-of-bound error
                 Key: DRILL-1100
                 URL: https://issues.apache.org/jira/browse/DRILL-1100
             Project: Apache Drill
          Issue Type: Bug
          Components: Client - JDBC, Client - ODBC
         Environment: SqlLine in Linux and C# in Windows
            Reporter: Alexander Zarei
            Priority: Minor


When an out of bound column is queried, for example, 

SELECT columns[12] as column_12  FROM `dfs`.`root`.`./sneaky.csv`;

the result is a column with all null values:

+------------+
| column_12  |
+------------+
| null       |
| null       |
| null       |
| null       |
| null       |
+------------+

However, it makes more sense to return an error instead.
