Was able to insert using the following error: INSERT INTO person(person_id, fname, lname, eye_color, birth_date) Is there a workaround by which I can pass null values to the primary key where the value of that column is from the sequence? Answer VALUES (null, 'William','Turner', 'BR', '') ĮRROR: null value in column "person_id" violates not-null constraintĭETAIL: Failing row contains (null, William, Turner, BR,, null, null, null, null, null). (person_id, fname, lname, eye_color, birth_date) Is there a one-line statement to add AUTO_INCREMENT to an existing column in Postgres?Īfter doing the boilerplate code, I am trying to INSERT using the following query: INSERT INTO person UPDATE test1 SET id = nextval('test_id_seq') īut this is too much boilerplate code. I have seen we can create a sequence in the following fashion ALTER SEQUENCE tablename_colname_seq OWNED BY lname ĬREATE SEQUENCE test_id_seq OWNED BY test1.id ĪLTER TABLE test ALTER COLUMN id SET DEFAULT nextval('test_id_seq')
Postgresql alter table only serial#
I have tried this in Postgres but I am getting this error: ALTER TABLE person ALTER COLUMN person_id SERIAL I want to add AUTO_INCREMENT in one ALTER statement the way we can do in MySQL ALTER TABLE person MODIFY person_id SMALLINT UNSIGNED AUTO_INCREMENT I have a database schema of the following table: database=# \d person
