Demo Database
In this tutorial we will use the well-known Northwind sample database.
Below is a selection from the "Orders" table:
OrderID | CustomerID | EmployeeID | OrderDate | ShipperID |
---|---|---|---|---|
10308 | 2 | 7 | 1996年09月18日 | 3 |
10309 | 37 | 3 | 1996年09月19日 | 1 |
10310 | 77 | 8 | 1996年09月20日 | 2 |
And a selection from the "Employees" table:
EmployeeID | LastName | FirstName | BirthDate | Photo |
---|---|---|---|---|
1 | Davolio | Nancy | 12/8/1968 | EmpID1.pic |
2 | Fuller | Andrew | 2/19/1952 | EmpID2.pic |
3 | Leverling | Janet | 8/30/1963 | EmpID3.pic |
MySQL RIGHT JOIN Example
The following SQL statement will return all employees, and any orders they might have placed:
Example
FROM Orders
RIGHT JOIN Employees ON Orders.EmployeeID = Employees.EmployeeID
ORDER BY Orders.OrderID;
Note: The RIGHT JOIN
keyword returns all records from the
right table (Employees), even if there are no matches in the left table
(Orders).
