Adding and subtracting date and time values

In this exercise, you will calculate the actual number of days rented as well as the true expected_return_date by using the rental_duration column from the film table along with the familiar rental_date from the rental table.

This will require that you dust off the skills you learned from prior courses on how to join two or more tables together. To select columns from both the film and rental tables in a single query, we'll need to use the inventory table to join these two tables together since there is no explicit relationship between them. Let's give it a try!

1
- Subtract the rental_date from the return_date to calculate the number of days_rented.
2
- Now use the AGE() function to calculate the days_rented.
