PDOException: SQLSTATE[42000]

У меня такой код:

 <?php
 $Code = $_POST['Code'];
 $email = $_SESSION['E-Mail'];
 echo "Code".$Code;
 var_dump($Code);

 //Проверки
 if ($Code = '') {
   http_response_code(500);
   exit();
 } else {
   if ($Code == $_SESSION['Verification_Code']) {
   $dsn = 'mysql:host=localhost;dbname=tsecret1_users;';
   $opt = [
     PDO::ATTR_ERRMODE            => PDO::ERRMODE_EXCEPTION,
     PDO::ATTR_DEFAULT_FETCH_MODE => PDO::FETCH_ASSOC,
     PDO::ATTR_EMULATE_PREPARES   => false,
   ];
  $pdo = new PDO($dsn, 'tsecret1_Sys', 'i$Q5-9J~.2m.', $opt);

  $sql = "UPDATE ? SET `parameters`='EmailVerified' WHERE `parameters` = 'EmailIsNotVerified'";
  $query = $pdo->prepare($sql);
  $query->execute([$email]);
  error_log($query, 0);
  echo '<h1 align="center">|!| Ваш E-Mail уде Подтвержден |!|</h1>';
}
} 
?>
