Understanding the SQL BETWEEN Operator

The SQL BETWEEN Operator is used in a WHERE clause to select a range of data between two values. This operator is inclusive: the beginning and end values are included in the range. Here’s a basic example:

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

Between Clause with Numbers

When used with numerical data, the BETWEEN Operator returns the records where the numerical column’s values are within the specified range. For example, if we have a products table and we want to find products priced between $10 and $50, we could use the following query:

SELECT product_name, price
FROM products
WHERE price BETWEEN 10 AND 50;

SQL BETWEEN Command with Text

The Clause can also be used with text values. When used with text, it returns the records where the textual column’s values fall within the specified range in the collating sequence. For example, if we want to select all products from a products table where the product name is between ‘A’ and ‘K’, we could use the following query:

SELECT product_name
FROM products
WHERE product_name BETWEEN 'A' AND 'K';

SQL BETWEEN with Dates

Yes, the SQL BETWEEN clause can be used with dates. It returns the records where date column’s values are within the specified range. Here’s an example where we select all orders from an orders table that were placed between January 1, 2022, and December 31, 2022:

SELECT order_id, order_date
FROM orders
WHERE order_date BETWEEN '2022-01-01' AND '2022-12-31';
