hi all
i have a table like this
CREATE SEQUENCE seq_student_id INCREMENT 1 START 1;
CREATE TABLE students (
student_id INT4 NOT NULL DEFAULT
NEXTVAL('seq_student_id'),
student_name text,
student_address text,
primary key(student_id)
)
CREATE TABLE student_club (
student_id INT4 NOT NULL;
club_id INT4,
CONSTRAINT student_id_update FOREIGN KEY(student_id)
REFERENCES students(student_id) ON UPDATE CASCADE
)
my question is how i can make auto insert student_id
on table student_club when i insert into table
students
example:
INSERT INTO students(student_name) VALUES('Willy');
table STUDENT
student_id | name | address
---------------------------------
1 | Willy |
and on TABLE student_club
student_id | club_id
--------------------
1 |
