How to Write and Call Stored Procedures in phpMyAdmin for Your MVC Application?

Writing Stored Procedures in phpMyAdmin: A Step-by-Step Guide

Storing procedures can simplify complex database operations. phpMyAdmin provides an easy way to create and manage stored procedures. Here's how to do it:

Creating a Stored Procedure:

1. Navigate to the Database: Log in to phpMyAdmin and select the database where you want to create the stored procedure.
2. Click 'Routines' Tab: In the header, click the 'Routines' tab.
3. Add a New Routine: Click the 'Add routine' button.
4. Write the Procedure: A popup window will appear. Enter the SQL code for your stored procedure.

Example:

<code class="sql">CREATE PROCEDURE get_customer_orders(IN customer_id INT)
BEGIN
    SELECT * FROM orders WHERE customer_id = customer_id;
END;</code>

5. Click 'GO': Once you've written the procedure, click the 'GO' button to create it.

Calling a Stored Procedure in MVC Architecture:

Once you have created the stored procedure, you can call it from your MVC architecture application. Here's how:

Model:

<code class="php"><?php

use PDO;

class CustomerModel
{
    private $db;

    public function __construct()
    {
        $this->db = new PDO(...);
    }

    public function getOrders($customerId)
    {
        $stmt = $this->db->prepare("CALL get_customer_orders(?)");
        $stmt->bindParam(1, $customerId, PDO::PARAM_INT);
        $stmt->execute();

        return $stmt->fetchAll();
    }
}</code>

Controller:

<code class="php">class CustomerController
{
    public function index($customerId)
    {
        $customerModel = new CustomerModel();
        $orders = $customerModel->getOrders($customerId);

        return view('customer/orders', ['orders' => $orders]);
    }
}</code>

By following these steps, you can easily write and call stored procedures in phpMyAdmin and integrate them into your MVC architecture application.
