How do I raise PDOException?

Question

This code works fine, but I\'ll want to handle exception if any thing goes wrong, so I deliberately made a syntax error in the query but nothing ha

Answer 1

Exceptions are thrown. Syntax errors in code != Exceptions.

<?php 
    try {
        $code = 12;
        throw new PDOException('Message', $code );
    } catch (PDOException $e) {

    }
?>

However, from the maual:

You should not throw a PDOException from your own code. See Exceptions for more information about Exceptions in PHP.

My advice is to throw either a general exception, or to write your own custom exception to handle your error.

Answer 2

Be sure to set the attribute PDO::ATTR_ERRMODE to PDO::ERRMODE_EXCEPTION, as soon as you init your pdo object:

$lecturers_db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

After that, any failed queries will raise an exception
