SQL Help, I am new to SQl and trying to solve:
For a book with ISBN 9780756404079, display its title, publisher, ISBN, which library (not branch) has it, and total number of copies each library has. Do not show libraries that dont carry it. Sort results by number of copies in decending order.
I tried:
Select Catalog_Item.Title,(select count(*) from book) as Number_of_Copies, Catalog_Item.publisher, Book.isbn, Library_Name
from catalog_Item, Library,book
where catalog_Item.catalog_Item_ID = Book.catalog_Item_ID and book.isbn = 9780756404079
order by Number_of_copies desc;
But it is only listing one book and the libraries that carry it, what do I fix?
