可以使用IN子句來代替相結合的“大于等于和小于等于”的條件。

要了解BETWEEN 子句考慮的EMPLOYEE_TBL表有以下記錄：

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)

現在，假設根據上表想獲取記錄條件daily_typing_pages超過170，等于和小于300。這可以使用如下條件>=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)

同樣可以實現使用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)
