How do you use the BETWEEN operator?

The BETWEEN operator in SQL is used to filter the result set within a specific range. It checks whether a value is within a given lower and upper bound (inclusive of both ends).

🔹 Syntax:

column_name BETWEEN lower_bound AND upper_bound

This is equivalent to:

column_name >= lower_bound AND column_name <= upper_bound

🔹 Example 1: Numeric Range

SELECT * FROM employees
WHERE salary BETWEEN 30000 AND 50000;

✅ This query will return all employees whose salary is between 30,000 and 50,000, inclusive.

🔹 Example 2: Date Range

SELECT * FROM orders
WHERE order_date BETWEEN '2024-01-01' AND '2024-12-31';

✅ This fetches all orders placed in the year 2024.

🔹 Example 3: Text Range (Alphabetical)

SELECT * FROM products
WHERE product_name BETWEEN 'A' AND 'M';

✅ This returns all products where the name starts with a letter between A and M.

🔸 Notes:

• The BETWEEN operator is inclusive — it includes both lower_bound and upper_bound.
• You can use NOT BETWEEN to exclude a range:

  SELECT * FROM employees
  WHERE salary NOT BETWEEN 30000 AND 50000;
  

Let me know if you want to try it with real-world data or combine it with JOIN, ORDER BY, etc.
