Connection.php中的Laravel QueryException第647​​行：SQLSTATE [42000]：語法錯誤或訪問衝突

Question

我試圖運行以下Query with Query builder。

$products = \DB::table('users') 
      ->join('products','products.auth_id','users.id') 
      ->leftjoin('buys','products.id','buys.product_id') 
      ->select('products.*','users.avatar',DB::raw('COUNT(buys.product_id) as total_sells')) 
      ->groupBy('products.id')    
      ->where('products.status','=','1') 
      ->take(20) 
      ->paginate(4); 

Where in products.id could be there in buys table or not.. 

但我得到以下錯誤。 我改變了database.php mysql array from strict = true to false。

QueryException in Connection.php line 647: 
SQLSTATE[42000]: Syntax error or access violation: 1055 'cart.products.name' isn't in GROUP BY 

Answer 1

嘗試

$products = \DB::table('users') 
->selectRaw('products.*,users.avatar, COUNT(buys.product_id) as total_sells') 
->where('products.status','=','1') 
     ->join('products','products.auth_id','=', 'users.id') 
     ->leftjoin('buys','products.id','buys.product_id') 
     ->groupBy('products.id')      
     ->take(20) 
     ->get(); 

我不知道如果PAGINATE將工作將查詢生成器。
