仅获取以下的最后五条记录是语法-

select *from yourTableName order by yourColumnName DESC LIMIT 5;

让我们首先创建一个表-

mysql> create table DemoTable820(
   Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   CustomerName varchar(100)
);

使用插入命令在表中插入一些记录-

mysql> insert into DemoTable820(CustomerName) values('Chris');
mysql> insert into DemoTable820(CustomerName) values('Robert');
mysql> insert into DemoTable820(CustomerName) values('David');
mysql> insert into DemoTable820(CustomerName) values('Bob');
mysql> insert into DemoTable820(CustomerName) values('Carol');
mysql> insert into DemoTable820(CustomerName) values('Adam');

使用select语句显示表中的所有记录-

mysql> select *from DemoTable820;

这将产生以下输出-

+----+--------------+
| Id | CustomerName |
+----+--------------+
|  1 | Chris        |
|  2 | Robert       |
|  3 | David        |
|  4 | Bob          |
|  5 | Carol        |
|  6 | Adam         |
+----+--------------+
6 rows in set (0.00 sec)

以下是将记录限制为仅最后五个结果的查询-

mysql> select *from DemoTable820 order by Id DESC LIMIT 5;

这将产生以下输出-

+----+--------------+
| Id | CustomerName |
+----+--------------+
|  6 | Adam         |
|  5 | Carol        |
|  4 | Bob          |
|  3 | David        |
|  2 | Robert       |
+----+--------------+
5 rows in set (0.00 sec)
