How do I create a table in a database?

In this example you can see how to create a table in MySQL database. We create a table called book with the following fields, id, isbn, title, published_year and price. We start by creating a connection to the database and execute the create table query.

package org.kodejava.jdbc;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;
import java.sql.Statement;

public class CreateTableExample {
    private static final String URL = "jdbc:mysql://localhost/kodejava";
    private static final String USERNAME = "kodejava";
    private static final String PASSWORD = "s3cr*t";

    public static void main(String[] args) {
        try (Connection connection =
                     DriverManager.getConnection(URL, USERNAME, PASSWORD)) {

            String sql = """
                    CREATE TABLE book
                    (
                        id             bigint(20) unsigned NOT NULL AUTO_INCREMENT,
                        isbn           varchar(50)         NOT NULL,
                        title          varchar(100)        NOT NULL,
                        published_year int(11)                      DEFAULT NULL,
                        price          decimal(10, 2)      NOT NULL DEFAULT '0.00',
                        PRIMARY KEY (id)
                    )
                    """;

            Statement statement = connection.createStatement();
            statement.execute(sql);
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}
