Only the User Number

A service check on orders returns only user_id for user_id = 7. Add an index on user_id so this tiny result can be produced as quickly as possible.

Speed this query up with an index
SELECT user_id FROM orders WHERE user_id = 7

CREATE/ALTER/DROP biss — l-ebda SELECT fl-aħħar mhu meħtieġ.
