> Info: The `save()` method will either perform an `INSERT` or `UPDATE` SQL statement, depending
on whether the ActiveRecord being saved is new or not by checking `ActiveRecord::isNewRecord`.
In order to load default values from database schema you may call `loadDefaultValues()` method:
```php
$customer = new Customer();
$customer->loadDefaultValues();
$cusomer->name = 'Alexander';
$customer->save();
```
