我有这个mysql表，我想选择最后10条记录，这是我的代码

SELECT * FROM mach_1 ORDER BY id DESC  LIMIT 10

问题是如何扭转这个

Answer 1

尝试这样的事情：

select * from (select * from mach_1 order by id desc 
limit 10) as tbl order by tbl.id;

Answer 2

很可能你不会绕过嵌套选择：

SELECT * FROM (SELECT * FROM mach_1 ORDER BY id DESC LIMIT 10) AS t ORDER BY t.id ASC

这将首先选择最后10个条目，然后按照您的意愿对它们进行升序排序。
