Interval data types

INTERVAL data types provide you with a very useful tool for performing arithmetic on date and time data types. For example, let's say our rental policy requires a DVD to be returned within 3 days. We can calculate the expected_return_date for a given DVD rental by adding an INTERVAL of 3 days to the rental_date from the rental table. We can then compare this result to the actual return_date to determine if the DVD was returned late.

Let's try this example in the exercise.
