MySQL 如何查找范围内的值

为此，在MySQL中使用BETWEEN运算符。让我们首先创建一个表 –

mysql> create table DemoTable
   -> (
   -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   -> Start int,
   -> End int
   -> );
Query OK, 0 rows affected (0.91 sec)

使用insert命令在表中插入一些记录 –

mysql> insert into DemoTable(Start,End) values(100,200);
Query OK, 1 row affected (0.17 sec)

mysql> insert into DemoTable(Start,End) values(400,500);
Query OK, 1 row affected (0.17 sec)

mysql> insert into DemoTable(Start,End) values(210,350);
Query OK, 1 row affected (0.11 sec)

使用select语句显示表中的所有记录 –

mysql> select *from DemoTable;

这将产生以下输出 –

+----+-------+------+
| Id | Start | End |
+----+-------+------+
|  1 |   100 | 200 |
|  2 |   400 | 500 |
|  3 |   210 | 350 |
+----+-------+------+
3 rows in set (0.00 sec)

以下是在MySQL中查找范围内的值的查询 –

mysql> select *from DemoTable WHERE 432 BETWEEN Start AND End;

这将产生以下输出 –

+----+-------+------+
| Id | Start | End  |
+----+-------+------+
|  2 |   400 | 500  |
+----+-------+------+
1 row in set (0.04 sec)
