What is the purpose of the BETWEEN operator in MYSQL?

-

In MySQL, the BETWEEN operator is used to filter the result set based on a specified range. It allows you to retrieve rows that have values within a specific range of values. The BETWEEN operator is inclusive, meaning that it includes the values specified in the range.

The basic syntax of the BETWEEN operator in MySQL is as follows:

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

In this syntax:

  • column_name(s) is the name of the column or columns you want to retrieve.
  • table_name is the name of the table from which you want to retrieve the data.
  • value1 and value2 define the range. Rows with values within this range (including value1 and value2) will be included in the result set.

Here's an example to illustrate how the BETWEEN operator works. Let's say you have a table named products with a column price. You want to retrieve all products with a price between $50 and $100:

sql code
SELECT*FROM products WHERE price BETWEEN50AND100;

This query will fetch all rows from the products table where the price column has a value between $50 and $100, inclusive.

Explain with Example

Let's consider a practical example using a hypothetical products table in a MySQL database. The products table might look like this:

idproduct_nameprice
1Laptop800
2Smartphone300
3Headphones50
4Tablet150
5Mouse20

Now, if you want to find products with prices between $50 and $200, you can use the BETWEEN operator in a SQL query:

sql code
SELECT * 
FROM products
WHERE price BETWEEN 50 AND 200;

The result of this query will include the following rows from the products table:
idproduct_nameprice
3Headphones50
4Tablet150

As you can see, only the rows with price values between 50 and 200 (inclusive) are included in the result set.

You can also use the BETWEEN operator with dates. Let's assume you have a sales table with a sale_date column in the format 'YYYY-MM-DD'. If you want to find sales made between '2023-01-01' and '2023-03-31', you can use the BETWEEN operator like this:

sql code
SELECT * 
FROM sales
WHERE sale_date BETWEEN '2023-01-01' AND '2023-03-31';

This query will retrieve all rows from the sales table where the sale_date falls between January 1, 2023, and March 31, 2023, inclusive.
