                            ## 更新數據表中的數據

~~~
DB::table('users')
            ->where('id', 1)
            ->update(['votes' => 1]);
~~~

## 自增或自減一個字段的值

~~~
DB::table('users')->increment('votes');
DB::table('users')->increment('votes', 5);
DB::table('users')->decrement('votes');
DB::table('users')->decrement('votes', 5);
~~~
也能夠同時指定其他要更新的字段：
~~~
DB::table('users')->increment('votes', 1, ['name' => 'John']);
~~~
