Jinfeng Ni created DRILL-1913:
---------------------------------
Summary: 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
Reporter: Jinfeng Ni
Priority: Minor
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.
