Exercise

Calculating the expected return date

So now that you've practiced how to add and subtract timestamps and perform relative calculations using intervals, let's use those new skills to calculate the actual expected return date of a specific rental. As you've seen in previous exercises, the rental_duration is the number of days allowed for a rental before it's considered late. To calculate the expected_return_date you will want to use the rental_duration and add it to the rental_date.

Instructions

  • Convert rental_duration by multiplying it with a 1-day INTERVAL.
  • Add it to the rental date.
