> I am using a CSV Data Context example with multiple fields - occurrences, first_name, last_name.
> Running this query -
> SELECT DISTINCT persons.csv.first_name FROM persons.csv
> This query performs a distinct across all the three columns and not just on the column adjacent to the DISTINCT keyword.
