Обсуждение: Question reagarding serial type.

Hi,

i have tried to find info elsewhere, but did not find anything to my satisfaction, so I was wondering if anyone on this
listcould point me into the right direction. 

When I create a table

e.g.:
create table xyz
(
  id    serial PRIMARY KEY,
  uvw   varchar2(100)
);

I would like to get the id returned when I insert into this table. In oracle it is possible to do this:
insert into xyz(uvw) values ('Test') returning id;

How can I do this with SQL in Postgres. Any ideas.

Thank you for any suggestions

  Mirko

    What if you had two serials?  I guess that's not terribly likely.

insert into xyz(uvw) values ('Test');
INSERT 18968479 1
dustin=# select currval('xyz_id_seq');
 currval
---------
       1
(1 row)
