>             Project: Apache Drill
>          Issue Type: Bug
>          Components: Client - JDBC, Client - ODBC
>         Environment: SqlLine in Linux and C# in Windows
>            Reporter: Alexander Zarei

> When an out of bound column in a CSV file 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 because the file has only 10
columns.
> The file content:
> someDirectoryFoo,true,false,false,100,root,root,"2013-10-11T14:31:58.000-0700","2013-10-11T14:31:58.000-0700","-rw-r--r--."
> someDirectoryBar,true,false,false,100,root,root,"2013-10-11T14:31:58.000-0700","2013-10-11T14:31:58.000-0700","-rw-r--r--."
