表mysql的第二行的第二行

Question

我在MySQL数据库中玩，只想查看表中倒数第二个但没有得到任何行的查询，下面给出了查询的问题。我的查询有什么问题

SELECT * FROM table WHERE id='(LAST_INSERT_ID()-1)'

Answer 1

LAST_INSERT_ID()-1 has no guarantee of pointing at an actual record. Try:

SELECT * FROM table ORDER BY id DESC LIMIT 1,1

Ideally you should be using something other than id to determine the age of a record, preferably a timestamp.
