[jira] [Created] (DRILL-6759) CSV 'columns' array is incorrectly case sensitive

Paul Rogers created DRILL-6759:
----------------------------------

             Summary: CSV 'columns' array is incorrectly case sensitive
                 Key: DRILL-6759
                 URL: https://issues.apache.org/jira/browse/DRILL-6759
             Project: Apache Drill
          Issue Type: Bug
    Affects Versions: 1.14.0
            Reporter: Paul Rogers


Perform the following query on a CSV file without column headers:
{noformat}
SELECT columns[0] FROM `yourFile.csv`
{noformat}

In Drill, column names are supposed to be case insensitive. So, let's try upper case:

{noformat}
SELECT COLUMNS[0] FROM `yourFile.csv`;
Error: DATA_READ ERROR: Selected column 'COLUMNS' must have name 'columns' or must be plain '*'
{noformat}

Expected {{`columns`}} to be case insensitive like other CSV columns and SQL keywords.
