🔢 Print Prime Numbers Using SQL | MySQL Recursive CTE Tutorial

In this video, learn how to generate prime numbers from 2 to 50 using only SQL! We use a powerful combination of recursive CTEs and JOINs in MySQL to identify prime numbers without using any procedural code or external logic.

📌 Query Used in This Video:

WITH RECURSIVE numbers AS (
SELECT 2 AS num
UNION ALL
SELECT num + 1 FROM numbers WHERE num less than symbol 50
),
divisors AS (
SELECT n.num, d.num AS div
FROM numbers n
JOIN numbers d ON d.num less than symbol n.num AND d.num greater than symbol 1
WHERE n.num % d.num = 0
)
SELECT num
FROM numbers
WHERE num NOT IN (SELECT num FROM divisors);
