可使用IN子句來取代相聯合的“年夜於等於和小於等於”的前提。

要懂得BETWEEN 子句斟酌的EMPLOYEE_TBL表有以下記載：

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)

如今，假定依據上表想獲得記載前提daily_typing_pages跨越170，等於和小於300。這可使用以下前提>=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)

異樣可以完成應用BETWEEN子句以下：

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)
