Laravel 5.4：如何通過計數（列）的口才？

Question

我試圖顯示最受門票排列的受讓人姓名assigned_to。

$accesses = Access::where('state','=','Assigned'); 

$all = Report::where('state', '=', 'Assigned') 
       ->union($accesses) 
       ->orderBy('count(assigned_to)') //THIS IS WRONG 
       ->get(); 

Answer 1

試試這個： -

$all = Report::where('state', '=', 'Assigned') 
      ->select(DB::raw('count(reports.assigned_to) as assigned_to')) 
      ->union($accesses) 
      ->orderBy('assignedto','DESC') 
      ->get(); 

Answer 2

你必須使用DB::raw得到它

$all = Report::where('state', '=', 'Assigned') 
      ->select(DB::raw('count(reports.assigned_to) as assigned_to')) 
      ->union($accesses) 
      ->orderBy('assigned_to','DESC') 
      ->get(); 

Answer 3

我想你可以試試這個：

$all = Report::where('state', '=', 'Assigned') 
      ->select(DB::raw('count(reports.assigned_to) as assigned_to'),DB::raw('count(access.assigned_to) as assigned_to_access')) 
      ->leftjoin('access','report.access.id','=','access.id') 
      ->union($accesses) 
      ->orderBy('assigned_to','DESC') 
      ->orderBy('assigned_to_access','DESC') 
      ->get(); 

希望這有助於爲你 ！！！

嘗試這樣

$accesses = Access::where('state','=','Assigned'); 

$all = Report::where('state', '=', 'Assigned') 
       ->union($accesses) 
       ->orderBy(DB::raw('count(assigned_to)'),'DESC') 
       ->get();
