Maatwebsite/Laravel Excel查询结果与下载的XLS不同

我查询了过去5天的出勤情况，包括员工Id、姓名、日期以及登录和注销时间

如果我在MySql中运行查询，它会返回正确的日期，但当我使用Maatwebsite/Laravel excel时，它似乎缺少一些记录

我试着做了一些研究，但我找不到一种方法来确定是什么导致了它

return $user = DB::table('users AS u')
   ->join('user_attendance AS a', function($join)
       {
        $join->on('u.user_id', '=', 'a.user_id')
        ->whereBetween('a.server_time', ["2019-10-01 00:00:00", "2019-10-15 23:59:59"]);
       })
       ->select('u.user_id', 'u.username',
                DB::raw(
                    'min(case when a.action = "IN" then date(a.server_time) end) `Date`,
                     min(case when a.action = "IN" then time(a.server_time) end) `IN`,
                     min(case when a.action = "OUT" then time(a.server_time) end) `OUT`'
                    )
                )
       ->groupBy('u.user_id', 'u.username', DB::raw('Date(a.server_time)'))
       ->orderBy('u.user_id')
       ->orderBy(DB::raw('Date(a.server_time)'))
       ->get();

如果我运行如下所示的查询，结果将是Mysql

| EmployeeId | EmployeeName |     Date    |     IN    |   OUT    |  
------------------------------------------------------------------
|  400442    |     Pooh     |  2019-10-02 |  08:49:02 | 18:08:00 |

但是，当我使用MaatWebsite/Laravel Excel在Laravel中运行代码时，它会返回不完整的日期。 这是我的密码

AutomailerController.php

namespace App\Http\Controllers;

use App\Exports\UsersExport;
use Maatwebsite\Excel\Facades\Excel;
use Maatwebsite\Excel\Concerns\FromQuery;
use Maatwebsite\Excel\Concerns\Exportable;
use DB;

class AutomailerController extends Controller
{
   use Exportable;

    public function export() 
    {
        return Excel::download(new UserLogs, 'users.xlsx');
    }
}

这是我的UserLogs.php

<?php

namespace App\Exports;

use Maatwebsite\Excel\Concerns\FromCollection;
use DB;

class UsersExport implements FromCollection
{
    /**
    * @return \Illuminate\Support\Collection
    */
    public function collection()
    {


        return $user = DB::table('users AS u')
                       ->join('user_attendance AS a', function($join)
                           {
                            $join->on('u.user_id', '=', 'a.user_id')
                            ->whereBetween('a.server_time', ["2019-10-01 00:00:00", "2019-10-15 23:59:59"]);
                           })
                           ->select('u.user_id', 'u.username',
                                    DB::raw(
                                        'min(case when a.action = "IN" then date(a.server_time) end) `Date`,
                                         min(case when a.action = "IN" then time(a.server_time) end) `IN`,
                                         min(case when a.action = "OUT" then time(a.server_time) end) `OUT`'
                                        )
                                    )
                           ->groupBy('u.user_id', 'u.username', DB::raw('Date(a.server_time)'))
                           ->orderBy('u.user_id')
                           ->orderBy(DB::raw('Date(a.server_time)'))
                           ->get();
    }
}

当我在Mysql上运行它时，我希望它的结果是相同的

后端是否发生了我错过的事情

谢谢。

文档上说don'y put get，可能就是这个错误。
