format-sql

Makes your SQL readable.

An example:

    sql = """ SELECT country, product, SUM(profit) FROM
sales   left join x on x.id=sales.k GROUP BY country,
product having f > 7 and fk=9 limit 5;    """

Will result in:

sql = """
    SELECT
        country,
        product,
        SUM(profit)
    FROM
        sales
        LEFT JOIN x ON
            x.id = sales.k
    GROUP BY
        country,
        product
    HAVING
        f > 7
        AND fk = 9
    LIMIT 5; """
