What are common errors encountered when using PDO for database queries in PHP?

One common error when using PDO for database queries in PHP is not properly handling exceptions. It is important to set PDO to throw exceptions on error so that you can catch and handle them appropriately. This can help in debugging and resolving issues with database queries. 

try {
    $pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch(PDOException $e) {
    echo "Connection failed: " . $e->getMessage();
}
