Use triggers to maintain referential integrity, PL-S, Basic Computer Science

Assignment Help:
At times, Brewbean''s has changed the id number for existing products. In the past, they have had to add a new product row with the new id to the BB_PRODUCT table, modify all the corresponding BB_BASKETITEM and BB_PRODUCTOPTION table rows, and then delete the original product row. Can a trigger be developed to avoid all these steps and handle the update of the BB_BASKETITEM and BB_PRODUCT OPTION table rows automatically for a given change in product id? If so, create the trigger and test by issuing an update statement, which changes the IDPRODUCT of 7 to 22. Do a rollback to return the data back to its original state. Also, disable the new trigger after you have completed the assignment.
