Orders for One User
The account page often opens orders for the user with user_id = 2. Add an index on user_id so fetching one user's orders does not require scanning the full table.
Speed this query up with an index
SELECT * FROM orders WHERE user_id = 2
Endast CREATE/ALTER/DROP — ingen avslutande SELECT behövs.
