Sql exists

Checks for the existence of any record within the subquery, returning true if
one or more records are returned.
Example: Lists any dealerships with a deal finance percentage less than 10.
SELECT dealership_name
FROM dealerships
WHERE EXISTS (SELECT deal_name FROM deals WHERE
dealership_id = deals.dealership_id AND finance_
percentage < 10);
