如何获取指定日期范围的值？

Question

我试图从表中检索今天的值，在我的表中我有created_at列，这是插入行时自动分配的时间戳。我还有一个send_at列，其中我手动插入datetime，当我查询send_at时它有效，但是当我查询created_at列时，我什么都没回来。

  $campaigns = SmsCampaign::whereBetween('created_at', array('2017-03-20 12:00:00','2017-03-20 23:59:00'))->paginate(10);

        return view('sms_campaign.smscampaign')->with('campaigns', $campaigns);

模型：

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class SmsCampaign extends Model
{


protected $table = 'sms_campaign';
protected $primaryKey = 'id';
//public $timestamps = false;
protected $fillable = [ 'campaign_name', 'content', 'phone_no_list',  'send_time', 'status', 'merchant_id', 'send_type'];




}

传递Carbon实例：

SmsCampaign::whereBetween('created_at', [
        Carbon::parse('2017-03-20 12:00:00'),
        Carbon::parse('2017-03-20 23:59.00')
    ])->paginate(10);
