MySQL 删除devices表中id最大的一行

原想法：delete from devices where id in (select max(id) from devices);

报错：ERROR 1093 (HY000): You can't specify target table 'devices' for update in FROM clause

网上查找原因说是：不能先select出同一表中的某些值，再update这个表(在同一语句中)

根据给出的解决方法优化为：

delete from devices where id in (select a.id from (select * from devices order by id desc limit 1) AS a );
