How do I execute stored procedure?

Stored-procedure are user-generated functions or procedures that, once created in the database, it can be called by the client applications, such as Java application. In this example we’ll demonstrate how to use the JDBC java.sql.CallableStatement to call a stored procedure. The store procedure in this example is just for selecting records from the products table.

package org.kodejava.jdbc;

import java.sql.*;

public class CallableStatementDemo {
    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 CallableStatement to execute the GetAllProducts() 
            // procedure.
            CallableStatement stmt =
                    connection.prepareCall("{CALL Get_All_Products()}");

            ResultSet rs = stmt.executeQuery();
            while ( {
                System.out.println(rs.getLong("id") + "\t"
                        + rs.getString("code") + "\t"
                        + rs.getString("name") + "\t"
                        + rs.getDouble("price"));
        } catch (SQLException e) {

Below is the stored procedure definition that was executed in the code above.

CREATE PROCEDURE `Get_All_Products`()
    SELECT * FROM product;

When running the code snippet, the result will be something like this:
