SQL RIGHT JOIN Keyword
SQL RIGHT JOIN Keyword
The RIGHT JOIN keyword returns all rows from the right table (table2), with the matching rows in the left table (table1). The result is NULL in the left side when there is no match.
SQL RIGHT JOIN Syntax
SELECT column_name(s)
FROM table1
RIGHT JOIN table2
ON table1.column_name=table2.column_name;
or:
SELECT column_name(s)
FROM table1
RIGHT OUTER JOIN table2
ON table1.column_name=table2.column_name;
PS! In some databases RIGHT JOIN is called RIGHT OUTER JOIN.
SELECT column_name(s)
FROM table1
RIGHT JOIN table2
ON table1.column_name=table2.column_name;
FROM table1
RIGHT JOIN table2
ON table1.column_name=table2.column_name;
SELECT column_name(s)
FROM table1
RIGHT OUTER JOIN table2
ON table1.column_name=table2.column_name;
FROM table1
RIGHT OUTER JOIN table2
ON table1.column_name=table2.column_name;

10309 | 37 | 3 | 1996-09-19 | 1 |
10310 | 77 | 8 | 1996-09-20 | 2 |
SQL RIGHT JOIN Example
The following SQL statement will return all orders, and any customers that might have placed them:
Example
SELECT Customers.CustomerName, Orders.OrderID
FROM Customers
RIGHT JOIN Orders
ON Customers.CustomerID=Orders.CustomerID
ORDER BY Customers.CustomerName;

Note: The RIGHT JOIN keyword returns all the rows from the right table (Orders), even if there are no matches in the left table (Customers).
SELECT Customers.CustomerName, Orders.OrderID
FROM Customers
RIGHT JOIN Orders
ON Customers.CustomerID=Orders.CustomerID
ORDER BY Customers.CustomerName;
FROM Customers
RIGHT JOIN Orders
ON Customers.CustomerID=Orders.CustomerID
ORDER BY Customers.CustomerName;
