I have a table with several columns + audit columns like INSERTED_BY, INSERT_DATE, UPDATED_BY, UPDATE_DATE. Whenever, this table is inserted or updated, I need to fill the audit columns via a database trigger. I need the body of the trigger. Please help me.

CREATE OR REPLACE TRIGGER IC_BIUR
BEFORE INSERT OR UPDATE OF LAST_NAME, FIRST_NAME
ON INSURANCE_CONTACTS
FOR EACH ROW
-- PL/SQL Block
begin
IF INSERTING THEN

ELSE -- if not inserting, then we are updating

END IF;
end;

For example:

CREATE OR REPLACE TRIGGER IC_BIUR
BEFORE INSERT OR UPDATE OF LAST_NAME, FIRST_NAME
ON INSURANCE_CONTACTS
FOR EACH ROW
-- PL/SQL Block
begin
IF INSERTING THEN

SELECT user, sysdate INTO :new.inserted_by, :new.insert_date FROM DUAL;

ELSE -- if not inserting, then we are updating

SELECT user, sysdate INTO :new.updated_by, :new.update_date FROM DUAL;

END IF;
end;

Just a note that you don't need to select from DUAL here:

:new.inserted_by := user;
:new.insert_date := sysdate;
