转换子选择到雄辩查询

Question

我有这个子选择查询，我希望能够转换为雄辩查询。任何人都可以帮忙吗？

$query = 'SELECT * FROM (SELECT * FROM `visits` WHERE `exit` = 0 ORDER BY `updated_at` DESC) visits GROUP BY `visits`.`session_id`'; 

感谢

Answer 1

得到的查询与工作联接：

Visit::select('visits.*')-> 
join(DB::raw('(SELECT * FROM `visits` WHERE `exit` = 0 ORDER BY `updated_at` DESC, `id` DESC) v2'), 'visits.id', '=', 'v2.id')-> 
groupBy('visits.session_id')->get();
