如何在Laravel中与RECURSIVE一起使用

Question

我有一个查询，但我不知道如何在Laravel中运行

WITH RECURSIVE category_path (id, name, lvl) AS(SELECT id, name, 0 lvl FROM category WHERE parent =1  UNION ALL SELECT c.id, c.name,cp.lvl + 1 FROM category_path AS cp JOIN category AS c ON cp.id = c.parent) SELECT * FROM category_path GROUP BY lvl ORDER BY lvl DESC limit 1

Answer 1

您可以使用DB::select('your query here'); 这是指向文档laravel

的官方链接

Answer 2

我认为您想使用原始查询，您可以尝试以下操作：

DB::select(DB::raw('your query here'));
