SQL BETWEEN 操作符
BETWEEN 操作符选取介于两个值之间的数据范围内的值。这些值可以是数值、文本或者日期。
SQL BETWEEN 语法
SELECT column_name(s)
FROM table_name
WHERE column_name BETWEEN value1 AND value2;
FROM table_name
WHERE column_name BETWEEN value1 AND value2;
演示数据库
在本教程中,我们将使用 RUNOOB 样本数据库。
下面是选自 "Websites" 表的数据:
mysql> SELECT * FROM Websites;
+----+---------------+---------------------------+-------+---------+
| id | name | url | alexa | country |
+----+---------------+---------------------------+-------+---------+
| 1 | Google | https://www.google.cm/ | 1 | USA |
| 2 | 淘宝 | https://www.taobao.com/ | 13 | CN |
| 3 | 菜鸟教程 | http://www.runoob.com/ | 5000 | USA |
| 4 | 微博 | http://weibo.com/ | 20 | CN |
| 5 | Facebook | https://www.facebook.com/ | 3 | USA |
| 7 | stackoverflow | http://stackoverflow.com/ | 0 | IND |
+----+---------------+---------------------------+-------+---------+
BETWEEN 操作符实例
下面的 SQL 语句选取 alexa 介于 1 和 20 之间的所有网站:
实例
SELECT * FROM Websites
WHERE alexa BETWEEN 1 AND 20;
WHERE alexa BETWEEN 1 AND 20;
执行输出结果:

实例
SELECT * FROM Websites
WHERE alexa NOT BETWEEN 1 AND 20;
WHERE alexa NOT BETWEEN 1 AND 20;

带有 IN 的 BETWEEN 操作符实例
下面的 SQL 语句选取 alexa 介于 1 和 20 之间但 country 不为 USA 和 IND 的所有网站:
实例
SELECT * FROM Websites
WHERE (alexa BETWEEN 1 AND 20)
AND country NOT IN ('USA', 'IND');
WHERE (alexa BETWEEN 1 AND 20)
AND country NOT IN ('USA', 'IND');
执行输出结果:

带有文本值的 BETWEEN 操作符实例
下面的 SQL 语句选取 name 以介于 'A' 和 'H' 之间字母开始的所有网站:
实例
SELECT * FROM Websites
WHERE name BETWEEN 'A' AND 'H';
WHERE name BETWEEN 'A' AND 'H';
执行输出结果:

带有文本值的 NOT BETWEEN 操作符实例
下面的 SQL 语句选取 name 不介于 'A' 和 'H' 之间字母开始的所有网站:

示例表
下面是 "access_log" 网站访问记录表的数据,其中:
- aid:为自增 id。
- site_id:为对应 websites表的网站 id。
- count:访问次数。
- date:为访问日期。
mysql> SELECT * FROM access_log;
+-----+---------+-------+------------+
| aid | site_id | count | date |
+-----+---------+-------+------------+
| 1 | 1 | 45 | 2016-05-10 |
| 2 | 3 | 100 | 2016-05-13 |
| 3 | 1 | 230 | 2016-05-14 |
| 4 | 2 | 10 | 2016-05-14 |
| 5 | 5 | 205 | 2016-05-14 |
| 6 | 4 | 13 | 2016-05-15 |
| 7 | 3 | 220 | 2016-05-15 |
| 8 | 5 | 545 | 2016-05-16 |
| 9 | 3 | 201 | 2016-05-17 |
+-----+---------+-------+------------+
9 rows in set (0.00 sec)
本教程使用到的 access_log 表 SQL 文件:access_log.sql。
带有日期值的 BETWEEN 操作符实例
下面的 SQL 语句选取 date 介于 '2016-05-10' 和 '2016-05-14' 之间的所有访问记录:
实例
SELECT * FROM access_log
WHERE date BETWEEN '2016-05-10' AND '2016-05-14';
WHERE date BETWEEN '2016-05-10' AND '2016-05-14';
执行输出结果:

请注意,在不同的数据库中,BETWEEN 操作符会产生不同的结果! 因此,请检查您的数据库是如何处理 BETWEEN 操作符! |
