如何使用ParseObject更新字段？

Question

How to use Extend to update the field?

Example SQL: UPDATE Empresa SET categorias = 'cat_01' WHERE id_user = 'dlkj83d'

$query = new ParseQuery('Empresa');
$query->equalTo("users", Session::get('user'));
$query->add("categorias", 'cat_01');   <- ERROR
$query->save();

Test

$query = new ParseQuery('Empresa');
$query->equalTo("users", Session::get('user'));

$empresa = new ParseObject($query);
$empresa->add('categorias', array('cat_01'));
$empresa->save();

Does not work.

Perfect.

    $query = new ParseQuery('Restaurante');
    $query->equalTo("users", Session::get('user'));

    $results = $query->first();
    $results->add('categorias', array('cat_02'));
    $results->save();

I still have some difficulties regarding the method NoSQL. Knowing that the reasoning is different.

Thank you for your attention.
