IN and BETWEEN

Filter with a list using IN and a range using BETWEEN.

IN and BETWEEN

IN filters values inside a list; BETWEEN filters values inside a range. IN is shorter than many = and OR.

SELECT name FROM products
WHERE price BETWEEN 10 AND 50;

BETWEEN includes both endpoints; 10 and 50 are in the result.

name is selected from products. WHERE keeps only the rows where price BETWEEN 10 AND 50 holds.

IN and BETWEEN — details

IN checks whether a value equals any value in a list. The list goes in parentheses, values separated by commas. It is cleaner than a long OR chain.

BETWEEN is for ranges: WHERE price BETWEEN 10 AND 50 includes both 10 and 50.

Practice IN and BETWEEN

Select name and price from products where price is between 10 and 50.

Starter code

query.sql
-- filter range with BETWEEN
SELECT name, price
FROM products
WHERE

Sample solution

query.sql
SELECT name, price
FROM products
WHERE price BETWEEN 10 AND 50

Expected output

name   price
Defter 12
Çanta  25
Kalem  10
