Can Some one please help me solve this subquery in mysql?

Question

***Rules: --- Do not use a join of any kind and do not use a correlated subquery. --- Do not use a comma join. --- If you use a join, you will get no points for that task. A From clause will reference only one table. --- DO not use a variable.

***Here is my problem: Display the book id and title for any books which someone has ordered and the book is both an SQL book and a atabase book. Use the Topic_id to filter for DB and SQL. Sort by the book_id.

***My answwer:

 select book_id, title
  From a_bkinfo.books
  Where book_id IN
    (Select book_id
     From a_bkinfo.book_topics
     Where topic_id = 'DB')
 And book_id in
    (Select book_id
     From a_bkinfo.book_topics
     Where topic_id = 'SQL')
     order by book_id; 

I received -2 on this problem. My teachers response: -2 * did not check that this book has been ordered.

***Here are the relevant tables.* Tables:

Answer 1

and book_id in 
    ( select d.book_id 
        from a_bkorders.order_details d
       where d.quantity > 0 
    )

---

Display the ID and title of the book(s) with the largest number of sales; include ties. For this query, use the total quantity sold. when determining the sales of a book

Without any JOIN operations or correlated subqueries, this will return the specified resultset:

SELECT b.book_id
     , b.title
  FROM a_bkinfo.books b
 WHERE b.book_id IN
       ( 
         SELECT d.book_id
           FROM a_bkorders.order_details d
          GROUP BY d.book_id
         HAVING SUM(d.quantity) =
                (
                  SELECT MAX(t.tot_quantity)
                    FROM (  
                           SELECT s.book_id
                                , SUM(s.quantity) AS tot_quantity
                             FROM a_bkorders.order_details s
                            GROUP BY s.book_id
                         ) t
                )
       )
