$builder->field(['id','title'])->get('user_list');
```

```php
$builder->fields(['id','title as notice'])->get('user_list');
$builder->field(['id','title as notice'])->get('user_list');
```

## 使用SQL函数

```php
$builder->fields(['id','SUM(score)'])->get('user_list');
$builder->field(['id','SUM(score)'])->get('user_list');
```
