How many titles did Mary Smith rent in 2005? Determine the percentage of titles rented in June 2005.
in June 2005 refers to month(rental_date) = 6 and year(rental_date) = 2005; percentage = divide(count(inventory_id where month(rental_date) = 6 and year(rental_date) = 2005), count(inventory_id)) * 100%
SELECT COUNT(T2.rental_id) , CAST(SUM(IIF(STRFTIME('%m',T2.rental_date) = '7', 1, 0)) AS REAL) * 100 / COUNT(T2.rental_id) FROM customer AS T1 INNER JOIN rental AS T2 ON T1.customer_id = T2.customer_id WHERE T1.first_name = 'Maria' AND T1.last_name = 'Miller' AND STRFTIME('%Y',T2.rental_date) = '2005'
