MySQL 如何在MySQL中限制仅显示最后五个结果

以下是获取仅最后五个记录的语法−

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)
);
Query OK, 0 rows affected (0.53 sec)

使用插入命令在表中插入一些记录−

mysql> insert into DemoTable820(CustomerName) values('Chris');
Query OK, 1 row affected (0.24 sec)
mysql> insert into DemoTable820(CustomerName) values('Robert');
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable820(CustomerName) values('David');
Query OK, 1 row affected (0.11 sec)
mysql> insert into DemoTable820(CustomerName) values('Bob');
Query OK, 1 row affected (0.09 sec)
mysql> insert into DemoTable820(CustomerName) values('Carol');
Query OK, 1 row affected (0.06 sec)
mysql> insert into DemoTable820(CustomerName) values('Adam');
Query OK, 1 row affected (0.08 sec)

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)

以下是限制记录仅显示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)
