26 Aug Consider your life as a relational database and define 5 triggers and 5 stored procedures that would be useful in your life.
We recently learned about triggers and stored procedures.
Consider your life as a relational database and define 5 triggers and 5 stored procedures that would be useful in your life. Write pseudo-code for such triggers and/or stored procedures. For example:
CREATE OR REPLACE TRIGGER brush_my_teeth
BEFORE UPDATE OR INSERT ON sleep_tracker
FOR EACH ROW
BEGIN
IF :NEW.datetime_went_to_bed IS NOT null
AND :NEW.did_brush_teeth IS FALSE THEN
RAISE_APPLICATION_ERROR(-20010,’I must brush my teeth before going to bed’);
END IF;
END;
