如何从查询中获取最大值/最大值？

Question

我想从此查询中获取包含 item_name 的最大值/最大值

这个显示值

[{"item_name":"accessories","items":"1"},{"item_name":"assets","items":"6"},{"item_name":"licenses","项目":"1"}]

     $max_fixassets = DB::table('assets')
    ->select('item_name')
    ->where('item_type','!=','Consumables')
    ->addselect(DB::Raw('sum(item_quantity) as items'))
    ->groupBy('item_name')
    ->get();

刀片

   {!!json_encode($max_fixassets)!!}

更新：确实尝试了其他方法，我确实获得了最大值，但现在问题是尝试放置时的项目名称

->select('item_name')

在查询中给了我错误的最大值

 $query_item = DB::table('assets')
    ->where('item_type','!=','Consumables')
    ->addselect(DB::Raw('sum(item_quantity) as items'))
    ->groupBy('item_name')
    ->get();

   $get_array=array();

    foreach($query_item as $query_item)
    {
        $get_array[]=$query_item;
        $max_fixassets=max($get_array);

    }

Answer 1

max('items')

 $max_fixassets = DB::table('assets')
    ->select('item_name')
    ->where('item_type','!=','Consumables')
    ->addselect(DB::Raw('sum(item_quantity) as items'))
    ->groupBy('item_name')->first();
