mysql中使用ORDER BY 之后再用Limit没有效果，使用Limit之后再用ORDER BY报错：ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use near 'limit
?0,10) order by id desc' at line 1

解决方法：

select * from (select * from p_picture where limit 0,10) order by id desc;

?这也写法是不对的，正确的写法如下：

select * from (select * from p_picture order by id desc) id limit 0,10;
