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)
