Piece of cake for you! Maybe the next one will be of some challenge?

Exercise

For each single rental, show the following columns: id, payment_date, payment_amount, the payment_amount of the previous single_rental in terms of the payment_date and the difference between the last two values.

Stuck? Here's a hint!

Use LAG(payment_amount) and order by the payment_date.
