ID update with various tables
Posted: Sun Jan 10, 2010 1:51 pm
Hello,
In facebook, or any other social networking websites. How are they really linking tables. I think they mostly does by ID. So when the users registers with register table, how to update the ID simultaneously with other tables like login,scrapbook,friendlist etc.?
