I want to know the publication price of the book with title "Cyberella"?
select t2.price from book as t1 join publication as t2 on t1.book_id = t2.book_id where t1.title = "Cyberella"
Could you show me all the books' publication price?
select t2.price from book as t1 join publication as t2 on t1.book_id = t2.book_id
Okay. I want all the books' titles in descending order of publication price.
select t1.title from book as t1 join publication as t2 on t1.book_id = t2.book_id order by t2.price desc
