SQL statement to get all customers with no orders

Question

I have a typical Persons table and an Orders table defined in such a way that I can do JOIN query as the following to return Orders for all Persons.

SELECT Perso         


        

Answer 1

Just for completeness, here is the not exists version:

select * from persons p 
where not exists
(select null from orders o where o.person_id = p.id)
