How to Create and Call Stored Procedures in phpMyAdmin Using the MVC Architecture?

Writing a Stored Procedure in phpMyAdmin: A Step-by-Step Guide

Trying to create and call stored procedures in phpMyAdmin can be confusing, especially when navigating its interface. Let's break down the process into simple steps while adhering to MVC architecture.

Creating a Stored Procedure

1. Access your database within phpMyAdmin.
2. Click on the "Routines" tab located in the header.
3. Select "Add routine."
4. In the pop-up window, enter your stored procedure definition and click "GO."
5. For instance, here's an example of a stored procedure:

CREATE PROCEDURE GetCustomerDetails(IN CustomerID INT)
BEGIN
    SELECT * FROM Customers WHERE CustomerID = CustomerID;
END

Calling the Stored Procedure

1. In the Model (Database Access Layer):

   • Establish a database connection.
   • Prepare a SQL statement using the PROCEDURE keyword:

<code class="php">$sql = "CALL GetCustomerDetails(?)";</code>

• Bind parameters if necessary.
• Execute the query.

2. In the Controller:

   • Instantiate the Model class.
   • Call the corresponding method to execute the stored procedure and pass parameters.
   • Return the result to the View.

3. In the View (Display Layer):

   • Receive the result from the Controller.
   • Display the data returned by the stored procedure.

This approach ensures separation of concerns and adheres to the MVC architecture, where business logic and data access are handled separately from presentation.
