Here are the relative create table statements and populate table statements that I have already done:
CREATE TABLE Customer ( cid CHAR(9) NOT NULL, name VARCHAR(20), address VARCHAR(80), PRIMARY KEY (cid) );
CREATE TABLE Orders ( oid CHAR(9) NOT NULL, order_date DATE, cid CHAR(9), PRIMARY KEY (oid) );
CREATE TABLE Book ( isbn CHAR(10) NOT NULL, title VARCHAR(100), btype VARCHAR(15), price DECIMAL(10,2), pub_date DATE, pid CHAR(10), PRIMARY KEY(isbn) );
CREATE TABLE Order_book ( oid CHAR(9), isbn CHAR(10), no_of_copy INT, CONSTRAINT fk_oid FOREIGN KEY(oid) REFERENCES Orders(oid), CONSTRAINT fk_isbn FOREIGN KEY(isbn) REFERENCES Book(isbn) );
INSERT INTO customer (cid, name, address) VALUES ('1', 'Mike Kay', '4914 Percheron Drive, Elk Grove, CA');
INSERT INTO book (isbn, title, btype, price, pub_date, pid) VALUES ('8330418998', 'Fundamentals of Database Systems', 'Textbook', 10.50, '2008-07-04', '200');
INSERT INTO book (isbn, title, btype, price, pub_date, pid) VALUES ('1234567890', 'Yes Man', 'Novel', 12.50, '2010-11-04', '200');
INSERT INTO book (isbn, title, btype, price, pub_date, pid) VALUES ('9210321309', 'Elenaor', 'Novel', 9.50, '2015-12-17', '200');
INSERT into orders (oid, order_date, cid) VALUES ('1', '2016-10-23', '1');
INSERT into orders (oid, order_date, cid) VALUES ('2', '2011-01-25', '1');
INSERT into orders (oid, order_date, cid) VALUES ('3', '2000-09-13', '1');
INSERT into orders (oid, order_date, cid) VALUES ('4', '2000-09-13', '1');
INSERT INTO order_book (oid, isbn, no_of_copy) VALUES ('1', '8330418998', 5);
INSERT INTO order_book (oid, isbn, no_of_copy) VALUES ('2', '1234567890', 1);
INSERT INTO order_book (oid, isbn, no_of_copy) VALUES ('3', '9210321309', 1);
INSERT INTO order_book (oid, isbn, no_of_copy) VALUES ('4', '2148481540', 1);
