What is the SQL schema structure for a ShoppingCart that includes tables named Spanner and Book?

edit

Here is an example SQL schema structure for a shopping cart that includes tables named Spanner and Book:

CREATE TABLE Spanner ( id INT NOT NULL, name VARCHAR(255) NOT NULL, price DECIMAL(10,2) NOT NULL, PRIMARY KEY (id) );

CREATE TABLE Book ( id INT NOT NULL, title VARCHAR(255) NOT NULL, author VARCHAR(255) NOT NULL, price DECIMAL(10,2) NOT NULL, PRIMARY KEY (id) );

A typical implementation of a shopping cart would include additional tables such as Customer, Order, and Orderline, which would store information about the customer, their orders, and the items in their orders.
