Question

This is how I do this in sql server.

insert into users(name) values('jhon');
set @id = @@identity; -- last serial

insert into usersroles(@id, 1)
insert into usersroles(@id, 2)
insert into usersroles(@id, 3)

How can I do the same in postgres (withouth creating a function)?

Answer 1

CREATE TABLE users (id SERIAL NOT NULL, name TEXT);
CREATE TABLE userroles (user_id INT NOT NULL, role_id INT NOT NULL);

INSERT
INTO    users (name)
VALUES  ('John');

INSERT
INTO    userroles (user_id, role_id)
VALUES  (CURRVAL('users_id_seq'), 1),
        (CURRVAL('users_id_seq'), 2),
        (CURRVAL('users_id_seq'), 3);
