oracle BETWEEN ? AND ?

在Oracle数据库中，`BETWEEN` 关键字用于在`SELECT`、`INSERT`、`UPDATE`或`DELETE`语句中指定一个范围，可以用来检索或操作在指定两个值之间的数据。`BETWEEN` 后面通常跟有两个值，表示范围的开始和结束，以及需要匹配的数据。

当你在查询或操作中使用`BETWEEN`时，它实际上会返回那些大于或等于开始值并且小于或等于结束值的记录。如果使用`?`作为占位符，它通常出现在预编译的SQL语句中，例如在使用Java的`PreparedStatement`时，你可以使用`?`来代替具体的值，然后在执行时绑定实际的参数。

这里有一个简单的例子来说明如何在SQL语句中使用`BETWEEN`：

SELECT * FROM employees WHERE salary BETWEEN 5000 AND 10000;

这个语句会返回`employees`表中所有工资在5000到10000之间的员工记录。

如果使用带有占位符的预编译语句，它可能看起来像这样：

SELECT * FROM employees WHERE salary BETWEEN ? AND ?;

在执行时，你需要提供两个参数来替换`?`，比如提供起始工资和结束工资。

ORACLE BETWEEN AND

ORACLE BETWEEN AND 是一种查询语句，用于查询某个字段在指定范围内的数据。例如，可以使用以下语句查询销售额在100到1000之间的订单：

SELECT * FROM orders WHERE sales BETWEEN 100 AND 1000;

其中，BETWEEN表示在两个值之间，AND表示两个值的范围。这个查询语句可以用于数字、日期等类型的数据。

oracle between and

The "between" operator in Oracle is used to specify a range of values for a column in a table. It is used in conjunction with the "and" operator to specify the upper and lower bounds of the range.

For example, the following query retrieves all rows from the "employees" table where the salary column is between $50,000 and $80,000:

SELECT * FROM employees
WHERE salary BETWEEN 50000 AND 80000;

The "between" operator is inclusive, meaning that values equal to the upper and lower bounds are included in the result set.

Note that the "between" operator can also be used with date and time values, as well as with character strings that can be sorted in a meaningful way.
