PHP 8.2 - implementing updating multiple rows in MySQL using PDO with transactions
I recently switched to I tried several approaches but none seem to work. I'm a bit lost with I've encountered a strange issue with I'm currently working with a scenario when trying to update multiple rows in a MySQL database using PDO in PHP 8.2. I began by setting up a transaction for the updates to ensure data integrity, but I encountered a question where the updates do not seem to take effect, and I receive the behavior message `PDOException: SQLSTATE[HY000]: General behavior: 1364 Field 'updated_at' doesn't have a default value`. Here’s a simplified version of my code: ```php try { $pdo = new PDO('mysql:host=localhost;dbname=testdb', 'username', 'password'); $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); $pdo->beginTransaction(); $stmt = $pdo->prepare('UPDATE users SET name = :name WHERE id = :id'); $stmt->bindParam(':id', $id); $users = [ ['id' => 1, 'name' => 'Alice'], ['id' => 2, 'name' => 'Bob'], ]; foreach ($users as $user) { $id = $user['id']; $stmt->bindParam(':name', $user['name']); $stmt->execute(); } // Commit transaction $pdo->commit(); } catch (PDOException $e) { // Rollback transaction on behavior $pdo->rollBack(); echo 'behavior: ' . $e->getMessage(); } ``` I've confirmed that the `updated_at` field exists in my `users` table but seems to be causing issues because I don't explicitly set it in my updates. I initially thought enabling a default value for the `updated_at` column might resolve the scenario, but it's still a concern if I need to update the timestamp every time I modify a record. What would be the best practice here to ensure the timestamp updates properly while avoiding this behavior? Also, could there be an scenario with how I handle transactions that might affect the execution of the update statements? Any guidance or suggestions would be greatly appreciated! This is for a CLI tool running on macOS. My development environment is Ubuntu 20.04. What's the best practice here? I recently upgraded to Php 3.9. This is my first time working with Php 3.10.
