RE: sequence primary key

Virginie,

Sounds like you could just user the SERIAL data type. Try:

CREATE TABLE toto (
toto_id SERIAL PRIMARY KEY
db TEXT);

Then whenver you do an insert...

INSERT INTO toto(db) VALUES ('and your little dog too!');

...you'll find that toto_id automagically increments for you.

Good luck. Hope this helps.

Subject: [NOVICE] sequence primary key

Hi all,

my question is about sequences and primary key of a table.
More details : I create a sequence and a table with these lines :

CREATE SEQUENCE "my_id" INCREMENT 1 MINVALUE 1 MAXVALUE 2147483647 START 1
CACHE 1;

CREATE TABLE "toto" (
"toto_id" integer PRIMARY KEY DEFAULT nextval('"my_id"'),
"db" text);

in a a sql file.
In fact, when I fill database I would like "toto_id" field to be filled
directly by sgdb by using sequence "my_id" but not by me.
This way doesn't work. It's perhaps a big mistake !!!
How is-it possible, so ?
Thanks a lot.

Virginie.
