SQL FULL OUTER JOIN Keyword
FULL OUTER JOIN
The FULL OUTER JOIN command returns all rows
when there is a match in either left table or right table.
The following SQL statement selects all customers, and all orders:
SELECT Customers.CustomerName, Orders.OrderID
FROM Customers
FULL OUTER JOIN Orders
ON Customers.CustomerID=Orders.CustomerID
ORDER BY Customers.CustomerName;
Note: The FULL OUTER JOIN keyword returns all the rows from
the left table (Customers), and all the rows from the right table (Orders). If
there are rows in "Customers" that do not have matches in "Orders", or if there
are rows in "Orders" that do not have matches in "Customers", those rows will be
listed as well.
