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.
