Description

Perform the following query on a CSV file without column headers:

SELECT columns[0] FROM `yourFile.csv`

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

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

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