在 SQL 中，可以使用 BETWEEN 关键字结合其他函数来执行更复杂的查询。以下是一些示例：
BETWEEN 和 AVG() 函数获取指定范围内的平均值：SELECT AVG(price) as average_price
FROM products
WHERE price BETWEEN 10 AND 50;
BETWEEN 和 SUM() 函数获取指定范围内的总和：SELECT SUM(sales) as total_sales
FROM sales_data
WHERE date BETWEEN '2021-01-01' AND '2021-12-31';
BETWEEN 和 COUNT() 函数获取指定范围内的记录数：SELECT COUNT(*) as total_records
FROM employees
WHERE salary BETWEEN 50000 AND 60000;
BETWEEN 和 MIN() 函数获取指定范围内的最小值：SELECT MIN(temperature) as lowest_temperature
FROM weather_data
WHERE date BETWEEN '2021-01-01' AND '2021-12-31';
BETWEEN 和 MAX() 函数获取指定范围内的最大值：SELECT MAX(temperature) as highest_temperature
FROM weather_data
WHERE date BETWEEN '2021-01-01' AND '2021-12-31';
这些示例展示了如何使用 BETWEEN 关键字与其他函数结合，以便在执行查询时获取所需的结果。
