如何在MYSQL数据库上进行逆序输出

Question

我有一个基本的写入和检索sql数据库php“事物”，我想按降序输出。我怎么做？

EG。最后一个条目首先显示，然后在此之前输入，然后在此之前输入...第一个条目是最后一个。

Answer 1

SELECT field_name
FROM table_name 
ORDER BY id DESC

默认情况下，如果要以相反的顺序显示，{mys}将以升序显示结果ORDER BY field_name DESC

您可以使用ID或日期作为字段名称

Answer 2

使用DESC ORDER BY排序。

SELECT * FROM <TABLE> ORDER BY <COLUMN> DESC

Answer 3

如果有自动增量字段，则按该字段排序，降序。

SELECT "column_name"
 FROM "table_name"
 [WHERE "condition"]
 ORDER BY "column_name" [ASC, DESC];

Answer 4

写下面的查询来检索数据

SELECT * FROM `table_name` order by id desc

它将按降序从表中检索数据

Answer 5

更改ORDER BY声明

• 从ORDER BY col或ORDER BY col ASC或ORDER BY col DESC
• 从ORDER BY col DESC到ORDER BY col ASC

Answer 6

MySQL 常规 选择的查询语法：

SELECT field1, field2,...fieldN FROM table_name 
[WHERE Clause][GROUP BY]
[ORDER BY][LIMIT]

示例查询1：

SELECT id,first_name,last_name,email FROM users ORDER BY first_name desc// In this case you can only fetch data by = id,first_name,last_name,email

示例查询2：

SELECT * FROM users ORDER BY first_name desc // In this case all fields will be selected

注意： ORDER BY ASC =数据将按升序排序＆amp; ORDER BY DESC =数据将按降序排序
