The BETWEEN operator in Oracle is used to check if a value lies within a specified range. It is commonly used in SQL queries to filter data based on a specific condition. The syntax for the BETWEEN operator in Oracle is as follows:
SELECT column_name
FROM table_name
WHERE column_name BETWEEN value1 AND value2;
In this example, "column_name" refers to the column in the table that we want to filter, "table_name" is the name of the table we are querying, and "value1" and "value2" are the lower and upper bounds of the range we want to filter. The operator checks whether the column value falls between the two given values and returns the rows that meet this condition.

BETWEEN是Oracle数据库中的一个关键字,用于在查询时根据某个范围内的值来检索数据库中的数据。通过使用BETWEEN子句,我们可以指定一个范围内的值,然后从表中检索满足该范围条件的数据。
例如,在给定的引用中,通过执行以下查询语句:
select * from Store_Information where time_date between '1992' and '2000';
这个查询将从名为Store_Information的表中检索出time_date列在1992年到2000年之间的数据。
因此,当你使用Oracle数据库时,可以使用BETWEEN关键字来查询满足指定范围条件的数据。

Oracle中的BETWEEN关键字用于确定一个值是否在两个值之间。语法结构如下:
```
value BETWEEN low_value AND high_value
```
其中 value 是需要检查的值, low_value 和 high_value 是范围边界。
例如:
```
SELECT * FROM employees
WHERE salary BETWEEN 3000 AND 5000;
```
该语句将查询员工表中工资在 3000 到 5000 之间的所有记录。
