Laravel - 高级碳日期查询

Question

我正在尝试编写某个查询，但我失败了，我正在寻求帮助

这就是我想做的事情

SELECT all items WHERE created_at is from before this month (July, June,...), and also 选择前 3 个在本月创建的

这是我目前拥有的。我已经尝试了很多次，但我无法找出正确的“WHERE”案例

   $offertes = DB::table('offertes')
      ->select('*')
      ->where('receiver_id', $user_id)
...
      ->orderby('seen')
      ->orderby('created_at','desc')
      ->get();

Answer 1

这样的事情应该可以工作：

$time = new Carbon\Carbon('first day of this month'); // Get first day of the month.
$time->setTime(0, 0, 0); // Set time to 00:00:00.
....
->where('created_at', '<', $time)
->where(function($q) {
    $q->where('created_at', '>', $time)
      ->orderby('created_at','asc') 
      ->take(3)
})
->get;
