 $users = DB::table('abctable')
        ->select(DB::raw('count(*) as count, MONTH(abctable.created_at) as MM, YEAR(abctable.created_at) as YY'))
        ->join('xyztable', 'n3d_sales_flat_order_grid.entity_id', '=', 'xyztable.parent_id')
        ->whereBetween('abctable.created_at',[new Carbon($fdate),new Carbon($gdate)])
        ->where('xyztable.city','like',$city)
        ->groupBy(DB::raw('MONTH(abctable.created_at)'),DB::raw('YEAR(abctable.created_at)'))
        ->get();
