PHP Echo $ info按降序排列

Question

好的，我的数据库名为'posts'

有6个字段

postid, title, message, date, time, day

每当我打印出每一行时，它都会向上打印出来？

表格

postid | 标题 |的消息

00001 | ........ | ........

<00> 00002 | ........ | ........

<00> 00003 | ........ | ........

当我打印出来时，就像

00001, ..., ...
00002, ..., ...
00003, ..., ...

但我想要

0003, ..., ...
0002, ..., ...
0001, ..., ...

有办法吗？我在谷歌找不到它......不管怎样，提前谢谢：）

Answer 1

SELECT `postid`, `title`, `message`, `date`, `time`, `day`
FROM `table1`
ORDER BY `postid` DESC;

Answer 2

试试这个，

select reverse(substr(reverse(postid), 1, 4)) as postid, title, message, date, time, day from posts order by postid desc;

假设您希望输出为4位而不是5

Answer 3

将此附加到您的查询中：

ORDER BY `postid` DESC

它会按降序排序，而不是按升序排序。

Answer 4

你可以试试这个 -

SELECT `postid`, `title`, `message`, `date`, `time`, `day`
FROM `tablename`
ORDER BY `postid` DESC;

你也可以

SELECT CONCAT(`postid`, ',', `title`, ',',  `message`, ',', `date`, ',', `time`, ',', `day`)
FROM `tablename`
ORDER BY `postid` DESC;

Answer 5

执行查询，例如SELECT postid, title, message, date, time, day FROM表格ORDER BY postid DESC

Answer 6

只需使用ORDER BY功能。

SELECT * FROM your_table ORDER BY postid DESC

DESC关键字只是颠倒了订单。
