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 string.

package org.kodejava.example.sql;

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

public class SelectStatementSample {
    public static void main(String[] args) throws Exception {
        Connection connection = null;
        try {
            // Register MySQL JDBC driver class.
            Class.forName("com.mysql.jdbc.Driver");

            // Get a connection to database.
            String url = "jdbc:mysql://localhost/kodejava";
            String user = "kodejava";
            String password = "kodejava123";
            connection = DriverManager.getConnection(url, user, password);

            // Create a statement object.
            Statement stmt = connection.createStatement();

            String sql = "INSERT INTO m_users (username, first_name, " +
                    "last_name, address) VALUES ('fbar', 'Foo', " +
                    "'Bar', 'Sunset Road 123')";

            // Call an execute method in the statement object 
            // and pass the query.
            stmt.execute(sql);
        } catch (ClassNotFoundException e) {
            System.err.println("Could not load database driver!");
        } catch (SQLException e) {
            e.printStackTrace();
        } finally {
            if (connection != null) {
                connection.close();
            }
        }
    }
}
