BETWEEN
The BETWEEN
operator selects values within a given range. The values can be numbers, text, or dates.
The BETWEEN
operator is inclusive: begin and end values are included.
Example
Select all products with a price between 10 and 15:
SELECT * FROM Products
WHERE Price BETWEEN 10 AND 15;
BETWEEN Text Values
The BETWEEN
operator can also be used on text values.
The result returns all records that are alphabetically between the specified values.
Example
Select all products between ‘Pavlova’ and ‘Tofu’:
SELECT * FROM Products
WHERE product_name BETWEEN 'Pavlova' AND 'Tofu';
If we add an ORDER BY
clause to the example above, it will be a bit easier to read:
Example
Same example as above, but we sort it by product_name
:
SELECT * FROM Products
WHERE product_name BETWEEN 'Pavlova' AND 'Tofu'
ORDER BY product_name;
BETWEEN Date Values
The BETWEEN
operator can also be used on date values.
Example
Select all orders between 12. of April 2023 and 5. of May 2023:
SELECT * FROM orders
WHERE order_date BETWEEN '2023-04-12' AND '2023-05-05';
