MySQL BETWEEN 没有端点?

如果您不想在中间包含结束值,请使用以下语法 −

SELECT * FROM yourTableName WHERE yourColumnName BETWEEN yourStartingValue and yourEndingValue and
   yourColumnName not in (yourEndingValue );

为了理解上述语法,让我们创建一个表。创建表的查询如下 −

mysql> create table BetweenWithoutEndPoints
   -> (
   -> Id int NOT NULL AUTO_INCREMENT,
   -> Name varchar(20),
   -> Age int,
   -> PRIMARY KEY(Id)
   -> );
Query OK, 0 rows affected (0.54 sec)

现在,您可以使用 insert 命令在表中插入一些记录。查询如下 −

mysql> insert into BetweenWithoutEndPoints(Name,Age) values('Mike',23);
Query OK, 1 row affected (0.21 sec)

mysql> insert into BetweenWithoutEndPoints(Name,Age) values('Larry',25);
Query OK, 1 row affected (0.21 sec)

mysql> insert into BetweenWithoutEndPoints(Name,Age) values('David',28);
Query OK, 1 row affected (0.16 sec)

mysql> insert into BetweenWithoutEndPoints(Name,Age) values('Sam',26);
Query OK, 1 row affected (0.15 sec)

mysql> insert into BetweenWithoutEndPoints(Name,Age) values('Carol',21);
Query OK, 1 row affected (0.14 sec)

mysql> insert into BetweenWithoutEndPoints(Name,Age) values('John',29);
Query OK, 1 row affected (0.18 sec)

mysql> insert into BetweenWithoutEndPoints(Name,Age) values('James',20);
Query OK, 1 row affected (0.41 sec)

mysql> insert into BetweenWithoutEndPoints(Name,Age) values('Robert',26);
Query OK, 1 row affected (0.17 sec)

mysql> insert into BetweenWithoutEndPoints(Name,Age) values('Michael',30);
Query OK, 1 row affected (0.16 sec)

使用 select 语句显示表中的所有记录。查询如下 −

mysql> select *from BetweenWithoutEndPoints;

输出结果如下:

+----+---------+------+
| Id | Name    | Age  |
+----+---------+------+
| 1 | Mike     | 23   |
| 2 | Larry    | 25   |
| 3 | David    | 28   |
| 4 | Sam      | 26   |
| 5 | Carol    | 21   |
| 6 | John     | 29   |
| 7 | James    | 20   |
| 8 | Robert   | 26   |
| 9 | Michael  | 30   |
+----+---------+------+
9 rows in set (0.00 sec)

这是 MySQL 的查询,不获取起点和终点。以下查询不包括 3 和 8:

mysql> select *from BetweenWithoutEndPoints
   -> where Id between 3 and 8 and Id not in (3, 8);

输出结果如下:

+----+-------+------+
| Id | Name  | Age  |
+----+-------+------+
|  4 | Sam   |   26 |
|  5 | Carol |   21 |
|  6 | John  |   29 |
|  7 | James |   20 |
+----+-------+------+
4 rows in set (0.04 sec)

如果您不想仅包含终点,请使用以下查询:

mysql> select *from BetweenWithoutEndPoints
-> where Id between 3 and 8 and Id not in (8);

输出结果如下:

+----+-------+------+
| Id | Name  | Age  |
+----+-------+------+
| 3  | David | 28   |
| 4  | Sam   | 26   |
| 5  | Carol | 21   |
| 6  | John  | 29   |
| 7  | James | 20   |
+----+-------+------+
5 rows in set (0.03 sec)
