mysql between 条件——迹忆客-ag捕鱼王app官网

可以使用between子句来替换“大于等于和小于等于”条件的组合。也就是between 表示字段值在给定的两个检索值之间。

between 语法

select column_name, function(column_name)
from table_name
where column_name  between value1 and value2;

示例

下面我们通过示例来进一步的了解between的用法。我们有一张employee_tbl表，数据记录如下：

 ------ ------ ------------ -------------------- 
|  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，根据上表数据，要获取条件 daily_typing_pages 大于等于 170 且小于等于 300 的记录。这可以使用>=和<=条件完成，如下所示 -

mysql>select * from employee_tbl 
   ->where daily_typing_pages >= 170 and
   ->daily_typing_pages <= 300;

结果如下：

 ------ ------ ------------ -------------------- 
|  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)

同样可以使用between子句实现如下 -

mysql> select * from employee_tbl 
   -> where daily_typing_pages between 170 and 300; 

结果如下：

 ------ ------ ------------ -------------------- 
|  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         |
 ------ ------ ------------ --------------------
