book_idbook_nametotal_vote, meaning the sum of votes received by that book
Calculate total_vote using a correlated subquery on book_stars.
Order the result by book_id.
Hints
Hint 1
The outer query should read from books b.
Hint 2
Inside the SELECT, use a subquery that sums vote from book_stars.
Hint 3
The correlation is bs.book_id = b.book_id: the subquery uses the book from the current row.
