How does a SPyQL query looks like?

  $ spyql “
    IMPORT pendulum AS p 
    SELECT
        (p.now() - p.from_timestamp(purchase_ts)).in_days() AS days_ago,
        sum_agg(price * quantity) AS total
    FROM csv
    WHERE department.upper() == 'IT' and purchase_ts is not Null
    GROUP BY 1
    ORDER BY 1
    TO json” < my_purchases.csv

The Readme is loaded with recipes and there is also a demo video: https://vimeo.com/danielcmoura/spyqldemo
