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select * from employee_tbl ->where daily_typing_pages >= 170 and ->daily_typing_pages 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)
