从mysql php中选择最后两行

Question

I have a database like this:

+----------+----------+------+
| username | password | time |
+----------+----------+------+
| a        | b        | 1234 |
| c        | d        | 5678 |
| e        | f        | 9012 |
+----------+----------+------+

Now I have to arrange this by time so I ran:

mysql_query("SELECT * FROM `table` ORDER BY `time`")

This showed me rows arranged by time in ascending order, but I have to get only username c and e or I have to get the last two rows from the query.

I have tried:

mysql_query('SELECT * FROM `table` ORDER BY `time` LIMIT 2')

But this showed me usernames a and c but I have to get the last two, how to do that?

Answer 1

SELECT * FROM table
ORDER BY time DESC
LIMIT 2

Answer 2

SELECT * FROM table ORDER BY time DESC LIMIT 2

添加DESC关键字将按降序对结果进行排序。

Answer 3

尝试这个：

SELECT * FROM table ORDER BY time DESC LIMIT 2

Answer 4

尝试

mysqli_query('SELECT * FROM table ORDER BY time DESC LIMIT 2')

Answer 5

Assuming you have an id field with AUTO_INCREMENT set.

To get the last two from the table .

SELECT * FROM table ORDER BY id DESC LIMIT 2
