Practice 1: Changes to data will only be allowed on tables during normal office hours of 8.45 in the morning until 5.30 in the afternoon, MONDAY through FRIDAY. A. Create a procedure called SECURE_DML that prevents the DML statement from executing outside of normal office hours, returning the message: “you may only make changes during normal office hours” b. Create a statement trigger on the PRODUCT table which calls the above procedure. c. Test it by inserting a new record in the PRODUCT table.
