选择MySQL范围内的特定行？

2024-04-20 07:42:05 316

让我们首先创建一个表-

mysql> create table DemoTable
   (
   Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   StudentName varchar(20)
   );

使用插入命令在表中插入一些记录-

mysql> insert into DemoTable(StudentName) values('John');
mysql> insert into DemoTable(StudentName) values('Carol');
mysql> insert into DemoTable(StudentName) values('David');
mysql> insert into DemoTable(StudentName) values('Bob');
mysql> insert into DemoTable(StudentName) values('Chris');
mysql> insert into DemoTable(StudentName) values('Robert');
mysql> insert into DemoTable(StudentName) values('Adam');
mysql> insert into DemoTable(StudentName) values('Mike');
mysql> insert into DemoTable(StudentName) values('Sam');

使用select语句显示表中的所有记录-

mysql> select *from DemoTable;

输出结果

+----+-------------+
| Id | StudentName |
+----+-------------+
| 1  | John        |
| 2  | Carol       |
| 3  | David       |
| 4  | Bob         |
| 5  | Chris       |
| 6  | Robert      |
| 7  | Adam        |
| 8  | Mike        |
| 9  | Sam         |
+----+-------------+
9 rows in set (0.00 sec)

这是选择特定行MySQL的查询-

mysql> select *from DemoTable ORDER BY Id DESC LIMIT 4 OFFSET 2;

输出结果

+----+-------------+
| Id | StudentName |
+----+-------------+
| 7  | Adam        |
| 6  | Robert      |
| 5  | Chris       |
| 4  | Bob         |
+----+-------------+
4 rows in set (0.00 sec)
