You are right, he was probably talking about FK's. I was just so frustrated about people insisting that using "ID" as the primary key in every table is a "good" idea,
I didn't bother to reply previously. I stand firm on my belief that the primary key should be something meaningful and NOT "id" just for the sake of having a unique numeric key.On Mon, Aug 24, 2015 at 8:39 PM, CaT <cat@zip.com.au> wrote:
