How Can I Manage and Utilize Stored Procedures in phpMyAdmin and PHP?

Managing and Utilizing Stored Procedures in phpMyAdmin and PHP

Despite the misconception, it is indeed possible to manage stored procedures using phpMyAdmin. To achieve this, follow these steps:

Creating Stored Procedures in phpMyAdmin

  1. In the SQL tab, set "Delimiter" to "//".
  2. Run the following query (modify as needed):
CREATE PROCEDURE sp_test()
BEGIN
  SELECT 'Number of records: ', count(*) from test;
END//
Copy after login

Using Stored Procedures from PHP

To execute a stored procedure in PHP, use a CALL query, as exemplified below:

<?php
$con = new mysqli("localhost", "username", "password", "database");
if ($con->connect_error) {
  die("Connection failed: " . $con->connect_error);
}

$sp_query = "CALL sp_test();";

if ($con->query($sp_query) === TRUE) {
  $result = $con->query("SELECT @num_records");
  if ($result->num_rows > 0) {
    $row = $result->fetch_assoc();
    echo "Number of records: " . $row["@num_records"];
  } else {
    echo "No records found";
  }
} else {
  echo "Error calling stored procedure: " . $con->error;
}

$con->close();
?>
Copy after login

Managing Stored Procedures

Stored procedures can be altered or dropped through phpMyAdmin. They can be found in the "Routines" fieldset below the tables in the Structure tab.

Advantages of Using Stored Procedures with PHP

Employing stored procedures with PHP offers several benefits:

  • Increased Performance: Stored procedures run on the database server, reducing the load on the PHP application.
  • Reduced Network Traffic: Stored procedures transmit data only once, improving performance.
  • Improved Security: Stored procedures can protect sensitive data by performing calculations on the database server, minimizing the risk of exposure.
