Question

I have a table in a MySQL table called persons

id  LastName    FirstName
1       Hansen      Timoteivn
2       Svendson    Tove
3       Pettersen   Kari

and another MySQL table called orders.

id  OrderNo  personID
1       77895    3
2       44678    3
3       22456    1
4       24562    1
5       34764    15

How can I write a SQL query that I feed into PHP’s mysql_query() function to return a list of “Order objects” that each contain a “Person object?” Each “Person object” has first name and last name as properties.

Answer 1

this query will return orders by a certain person (this will not give the object)

SELECT a.ID, a. FirstName, a.LastName, b.OrderNo
FROM Persons a INNER JOIN Orders b ON
        a.ID = b.PersonID
WHERE a.ID = 1
