选择MySQL范围内的特定行?
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)
