SQL BETWEEN Operator: Selecting Values within a Range - Comprehensive Guide

The SQL BETWEEN operator is used to select values within a range. The syntax for the BETWEEN operator is as follows:

SELECT column_name(s) FROM table_name WHERE column_name BETWEEN 'value1' AND 'value2';

This will select all rows where the value in the column_name is between 'value1' and 'value2', inclusive. The BETWEEN operator can be used with any data type, including dates and strings.

For example, if you wanted to select all customers whose order date is between January 1, 2021 and March 31, 2021, you would use the following query:

SELECT customer_name, order_date FROM orders WHERE order_date BETWEEN '2021-01-01' AND '2021-03-31';

This would return a list of customer names and order dates for all orders placed between January 1st and March 31st of 2021.
