Creating a trigger with a case statement

Question

I have these two tables:

USERS(username, role_id)
COMMISSION_RATES(username, commission_rate)

users.username is the primary ke

Answer 1

It should go like this:

CREATE OR REPLACE TRIGGER SETCOMISSIONRATE 
AFTER INSERT ON USERS FOR EACH ROW
WHEN (new.role_id = 2)
BEGIN
    INSERT INTO COMISSION_RATE (username, comission_rate)
    VALUES (:new.username, 0);
END;
