Date: Tue, 29 Jan 2008 19:47:54 -0800 (PST)
I am new to Oracle and today someone asked me about the "fference between unique_id and primary key. Which to use and why?" I know about the primary key but not unique_id. Can someone kindly give me an overview of it?
Thanks in advance. Received on Tue Jan 29 2008 - 21:47:54 CST
