Retrieve Related Data Using INNER JOIN

Master SQL INNER JOIN to combine rows from two or more tables based on a related column, essential for retrieving comprehensive datasets from relational databases.

SELECT
  u.id AS user_id,
  u.username,
  o.order_id,
  o.order_date,
  o.total_amount
FROM
  users u
INNER JOIN
  orders o ON u.id = o.user_id
WHERE
  u.id = 101;

How it works: This snippet uses an `INNER JOIN` to combine records from the `users` table and the `orders` table. It links them where `users.id` matches `orders.user_id`, allowing you to fetch specific user details alongside their corresponding order information, filtered for a particular user ID.
