>             Project: Apache Drill
>          Issue Type: Bug
>          Components: SQL Parser
>            Reporter: Jinfeng Ni

> For the following query,
> {code}
> select EMPLOYEE_ID from cp.`employee.json` limit 2;
> +-------------+
> | employee_id |
> +-------------+
> | 1           |
> | 2           |
> +-------------+
> {code}
> Even though upper-case EMPLOYEE_ID matches the field 'employee_id' in the input JSON file, Drill did not preset the upper-case in the output result, which seems to be not right.
> The plan coming out of optiq/calcite seems right, as it has a project which will do the renaming. But Drill's logical planning will remove such project, hence not being able to preserve the upper-case in the output.
