How do I delete records from database using JdbcTemplate?

The code below demonstrates on how to delete some records from database using the JdbcTemplate.

package org.kodejava.example.spring.jdbc;

import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.datasource.DriverManagerDataSource;

import javax.sql.DataSource;

public class DeleteDemo {
    public static final String DRIVER = "com.mysql.jdbc.Driver";
    public static final String URL = "jdbc:mysql://localhost/mediadb";
    public static final String USERNAME = "root";
    public static final String PASSWORD = "";

    public static final String QUERY = "DELETE FROM records WHERE id = ?";

    private DataSource dataSource;

    public DeleteDemo(DataSource dataSource) {
        this.dataSource = dataSource;

    public void deleteRecord(Long id) {
        // Creates an instance of JdbcTemplate and supply a data
        // source object.
        JdbcTemplate template = new JdbcTemplate(this.dataSource);

        // Delete a student record from database where the students
        // id matches with the specified parameter.
        Object[] params = {id};
        int rows = template.update(DeleteDemo.QUERY, params);
        System.out.println(rows + " row(s) deleted.");

     * Returns a DataSource object.
     * @return a DataSource.
    public static DataSource getDataSource() {
        DriverManagerDataSource ds = new DriverManagerDataSource();
        return ds;

    public static void main(String[] args) {
        DataSource ds = getDataSource();
        DeleteDemo demo = new DeleteDemo(ds);

        Long id = 1L;
