When you use serial a kind of macro is performed: in fact an integer field is
created, a sequence is created with a name based on the table's name and the
nextval of that sequence is used as the default value for the field. Now you
have to do these steps "manually".
CREATE SEQUENCE "public"."tbl_all_ID_seq" INCREMENT 1 MINVALUE 1 START 1 CACHE
1;
CREATE TABLE tbl_first (
id INTEGER DEFAULT nextval('public."tbl_all_ID_seq"'::text) NOT NULL,
testo text
);
CREATE TABLE tbl_second (
id INTEGER DEFAULT nextval('public."tbl_all_ID_seq"'::text) NOT NULL,
testo text
);

Hi everybody,
I need to have a primary key which has to be unique on two tables.
E.g.:
CREATE TABLE first
(
id serial NOT NULL,
testo text,
)
CREATE TABLE second
(
id serial NOT NULL,
testo text,
)
When I insert some text on "first", I would like first.id = second.id
+ 1, and vice versa.
A sort of primary key in common for both tables.
Any hints?
Thank you very much
