How do I insert a record into database table?

In this example you’ll learn how to create a program to insert data into a database table. To insert a data we need to get connected to a database. After a connection is obtained you can create a java.sql.Statement object from it, and using this object we can execute some query strings.

package org.kodejava.jdbc;

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

public class InsertStatementExample {
    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)) {

            // Create a statement object.
            Statement stmt = connection.createStatement();
            String sql = "INSERT INTO book (isbn, title, published_year) " +
                    "VALUES ('978-1617293566', 'Modern Java in Action', 2019)";

            // Call execute() method of the statement object and pass the
            // query.
            stmt.execute(sql);
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }
}

Below is the script from creating the book table.

CREATE TABLE `book`
(
    `id`             bigint(20) unsigned                  NOT NULL AUTO_INCREMENT,
    `isbn`           varchar(50) COLLATE utf8_unicode_ci  NOT NULL,
    `title`          varchar(100) COLLATE utf8_unicode_ci NOT NULL,
    `published_year` int(11)                                       DEFAULT NULL,
    `price`          decimal(10, 2)                       NOT NULL DEFAULT '0.00',
    PRIMARY KEY (`id`)
) ENGINE = InnoDB
  DEFAULT CHARSET = utf8
  COLLATE = utf8_unicode_ci;
