Обсуждение: ROWID ? or other internal ID

I'm beginner with postgresql.
In other database like ORACLE or PROGRESS you've got an internal identifier
ROWID or RECID
(bookmark with access) which allow you to select a row very quickly or to go
back to a specific row very quickly.
these functions uses an internal ID.

Does something approaching that exist under postgresql ?
I've search and found nothing except "SERIAL" but that's not an internal ID.

thanks,

Stéphane Valcauda

You want OID as in:

Select OID, * from table;

CTID allows direct access to a row --- but it's invalidated by an
update, so it might not be very useful for you.

Hi!

I'm new in postgresql-ODBC but not in postgresql. I use it with PHP long
time ago.
I use OID for selecting and also for referencing rows. For this I need to
know the OID of the last inserted row. In php I have getlastoid function
for this.
I tried "insert" then "select :LASTOID" with ODBC but it has returned with
error. (I tried it in the same connection)
How can I get the OID of last inserted row with ODBC?

Thanks
Zoltan

In PL/pgSQL you can :

GET DIAGNOSTICS {variable} = RESULT_OID;

to get the OID of the previous INSERTed, DELETEd or UPDATEd row.

Ok, but how can I use this with ODBC?

Just create a stored procedure that returns RESULT_OID;
