case #3, Foodie_fi, problem 7

Hi Katie,

Thank you so much for uploading the solutions and explaining them aptly.

To my understanding, in this solution, next_date should be 'not null.' ( your query says - next_date is null)
As we need the latest subscription on or before 2020-12-31. Next_date column gives the dates for latest subcription date.
Using 'not null' we will only get the dates when new subscription was taken.

Please help me understand this better.

Thank you and happy learning!
Rishi
