我在laravel 8中计算值时遇到问题.我想计算表中的所有值下面那个已经进入并且还没有状态.如何计算laravel eloquent中没有状态的值，它是由member_Code分组的

I have trouble in counting values in laravel 8. I want to count all in the table below that have in and doesnt have a status out yet. How to count value that is doesnt have status out in laravel eloquent it is group by member_Code

推荐答案

你可以像这样使用 DB::raw 进行计数:

you can count using DB::raw like this:

  $values=   MyModel::query()->where('status', '!=', 'out')
            ->select(['member_Code',DB::raw('count(*)')]) ->groupBy('member_Code')->get();

如果要统计所有尚未超时的成员，可以使用distinct 方法:

if you want to count all member that don't time out yet, you can use distinct method:

 $inMemebersCount= MyModel::query()->where('status', '!=', 'out')
            ->select('member_Code')->distinct()->count();
