Jacques Nadeau updated DRILL-1913:
----------------------------------
Fix Version/s: (was: 1.0.0)
1.2.0
> Drill did not correctly preserve output field's case sensitivity
> ----------------------------------------------------------------
>
> Key: DRILL-1913
> URL: https://issues.apache.org/jira/browse/DRILL-1913
> Project: Apache Drill
> Issue Type: Bug
> Components: SQL Parser
> Reporter: Jinfeng Ni
> Assignee: Jinfeng Ni
> Priority: Minor
> Fix For: 1.2.0
>
>
> 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.
