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)
