MySQL中获取范围内值的BETWEEN子句的替代方法是什么？

为避免使用BETWEEN子句，您可以使用AND来获取范围内的值。让我们首先创建一个表 –

mysql> create table DemoTable
(
  Number int
);
Query OK, 0 rows affected (0.62 sec)

使用insert命令将一些记录插入表中 –

mysql> insert into DemoTable values(10);
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable values(20);
Query OK, 1 row affected (0.24 sec)
mysql> insert into DemoTable values(60);
Query OK, 1 row affected (0.10 sec)
mysql> insert into DemoTable values(100);
Query OK, 1 row affected (0.07 sec)
mysql> insert into DemoTable values(90);
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable values(85);
Query OK, 1 row affected (0.12 sec)

使用select语句从表中显示所有记录 –

mysql> select *from DemoTable −

这将产生以下输出 –

+--------+
| Number |
+--------+
|     10 |
|     20 |
|     60 |
|    100 |
|     90 |
|     85 |
+--------+
6 rows in set (0.00 sec)

以下是在不使用BETWEEN子句的情况下获取范围内的值的查询 –

mysql> select *from DemoTable where 15 <=Number and Number <= 80;

这将产生以下输出 –

+--------+
| Number |
+--------+
|     20 |
|     60 |
+--------+
2 rows in set (0.00 sec)
