SQL: FULL OUTER JOIN

FULL OUTER JOIN is a join that returns all the results from the left hand side of the = sign and all the results of the right hand side. For example this query returns all the customers and all the orders in one result

SELECT c.ContactName, o.OrderID
FROM Customers c
FULL OUTER JOIN Orders o
ON c.CustomerID=o.CustomerID
ORDER BY c.ContactName
