I have an article with ID 1 let's say. And within this article I have three content parts for example: 2, 3 and 4. Now here's what I want: I want to know how I can query the article with ID 1 to get the content part number 3. Anyone knows how to do it?
The whole id, a_id, u_id fields within the MySQL table are really tricky if you don't know the meaning. Maybe someone can tell me if not able to answer my question above.
Thanks in advance!
