为此，请使用BETWEEN关键字。让我们首先创建一个表-

mysql> create table DemoTable1537
   -> (
   -> StudentId 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 DemoTable1537(StudentName) values('Chris');
mysql> insert into DemoTable1537(StudentName) values('Bob');
mysql> insert into DemoTable1537(StudentName) values('Sam');
mysql> insert into DemoTable1537(StudentName) values('Mike');
mysql> insert into DemoTable1537(StudentName) values('David');
mysql> insert into DemoTable1537(StudentName) values('John');
mysql> insert into DemoTable1537(StudentName) values('Carol');

使用select语句显示表中的所有记录-

mysql> select * from DemoTable1537;

这将产生以下输出-

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

以下是显示多个输入值的查询-

mysql> select StudentName from DemoTable1537 where StudentId between 3 and 6;

这将产生以下输出-

+-------------+
| StudentName |
+-------------+
| Sam         |
| Mike        |
| David       |
| John        |
+-------------+
4 rows in set (0.00 sec)
