是否可以从 MySql 中的 table 中删除一行或多行？我想从以下 table 中删除最后两行。

+-------+--------------+-----------+--------------------+---------------+
|     1 |           15 | 375000.00 |                  2 | 2015-05-01    |

Answer 1

如果 gp_no 是主键并且自动递增，您可以删除最后 2 条记录作为

delete from table_name order by gp_no desc limit 2

Answer 2

delete from table_name order by gp_no desc limit 2

答案在评论中给出清楚

Answer 3

首先您需要确定行的顺序。假设您的第一列是唯一的；

DELETE FROM tbl WHERE 1 ORDER BY gp_no DESC LIMIT 2

但您可能还想根据日期明确删除最后两行，比如最近的 starting_dates

DELETE FROM tbl WHERE 1 ORDER BY starting_date DESC LIMIT 2
