MySQL中BETWEEN子句的用法详解

可以使用IN子句来代替相结合的“大于等于和小于等于”的条件。
要了解BETWEEN 子句考虑的EMPLOYEE_TBL表有以下记录：

mysql> SELECT * FROM employee_tbl;+------+------+------------+--------------------+| id| name | work_date | daily_typing_pages |+------+------+------------+--------------------+|1 | John | 2007-01-24 |250 ||2 | Ram | 2007-05-27 |220 ||3 | Jack | 2007-05-06 |170 ||3 | Jack | 2007-04-06 |100 ||4 | Jill | 2007-04-06 |220 ||5 | Zara | 2007-06-06 |300 ||5 | Zara | 2007-02-06 |350 |+------+------+------------+--------------------+7 rows in set （0.00 sec）

现在，假设根据上表想获取记录条件daily_typing_pages超过170，等于和小于300。这可以使用如下条件>=和<=

mysql>SELECT * FROM employee_tbl ->WHERE daily_typing_pages >= 170 AND->daily_typing_pages <= 300;+------+------+------------+--------------------+| id| name | work_date | daily_typing_pages |+------+------+------------+--------------------+|1 | John | 2007-01-24 |250 ||2 | Ram | 2007-05-27 |220 ||3 | Jack | 2007-05-06 |170 ||4 | Jill | 2007-04-06 |220 ||5 | Zara | 2007-06-06 |300 |+------+------+------------+--------------------+5 rows in set （0.03 sec）

同样可以实现使用BETWEEN子句如下：

mysql> SELECT * FROM employee_tbl -> WHERE daily_typing_pages BETWEEN 170 AND 300; +------+------+------------+--------------------+| id| name | work_date | daily_typing_pages |+------+------+------------+--------------------+|1 | John | 2007-01-24 |250 ||2 | Ram | 2007-05-27 |220 ||3 | Jack | 2007-05-06 |170 ||4 | Jill | 2007-04-06 |220 ||5 | Zara | 2007-06-06 |300 |+------+------+------------+--------------------+5 rows in set （0.03 sec）
