法律研究没有端点的 MySQL BETWEEN？
如果不想包含之间的结束值，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，可以使用插入命令向表中插入一些记录。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)使用选择语句显示表中的所有记录。查询如下 -
mysql> select *from BetweenWithoutEndPoints;
以下是输出
+----+---------+------+ | 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)
以下是没有获取开始和结束点的 MySQL between 查询。下面的查询不包含 3 和 8
mysql> select *from BetweenWithoutEndPoints -> where Id between 3 and 8 and Id not in (3, 8);
以下是输出
+----+-------+------+ | Id | Name | Age | +----+-------+------+ | 4 | Sam | 26 | | 5 | Carol | 21 | | 6 | John | 29 | | 7 | James | 20 | +----+-------+------+ 4 rows in set (0.04 sec)
如果您只想不包含结束点，请使用以下查询
mysql> select *from BetweenWithoutEndPoints -> where Id between 3 and 8 and Id not in (8);
以下是输出
+----+-------+------+ | 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)
