You have chosen wisely
It has been years since I wrote any SQL, so I may just be missing something but:
Why is the "As it could be" example for the second example using sub selects?!
Especially the one in the where clause where they are selecting two tables that they already joined in the from clause?
And wouldn't it be quicker to join the review table and use a group by?
Exactly!
