Thread: automatic creation of oid
Hi, I'm new to postgresql. How can automatically create unique object identifyer during insertion of new data. I 've seen that a can use a sequence, but I think there must be another way? ciao Detlef -- # Dipl. Ing. (FH) Detlef Jockheck # E-mail: detlef@jockheck.de # -------------------------------

Hi Oliver, Yes! Thats what I was looking for. I've seen it in the documentation but could'nt remember how it works. Thanks for the tip :-) ciao Detlef -- # Dipl. Ing.

But if you don't have any other requirements than what you mentioned, you should use sequence/serial. Regards, Link.
