Explanation / Answer

select * from book where Publish_date >'1978-1-1' and Book_title LIKE '%Sea%';

UPDATE book SET Quantity= 0 WHERE Publish_date<'1975-1-1';

select AVG(Quantity) from book where Publish_date<'1980-1-1';

select Quantity number,Autor from book;

select Author from book where COUNT(Quantity number)>1;


select loan_id from loan_event,customer where customer.customer_id=loan_event.customer_id and customer.customer_name='john';

select loan_date from loan_event,customer where customer.customer_id=loan_event.customer_id and customer.customer_name='john';

select loan_event.loan_id,customer.customer_id from loan_event,customer where customer.customer_id=loan_event.customer_id ;

select book.Book_title from book,customer,loan_detail where customer.customer_id = loan_detail.customer_id and
loan_detail.book_id = book.Book_id;

SELECT customer.customer_name,
SUM(loan_event.paymentnumber)
FROM customer,loan_event
WHERE customer.customer_id=loan_event.customer_id
GROUP BY customer.customer_name,loan_event.paymentnumber;
