What to do:
A simple database composed of the following tables: MEMBERSHIP, RENTAL,
DETAILRENTAL, PRICE, MOVIE, and VIDEO, is now loaded with this assignment and you are
ready to start. Please explore the database and then write the appropriate PL/SQL to
answer the following questions.
1. Create a trigger that will write the correct value to DETAIL_DAYSLATE in the DETAILRENTAL
table whenever a video is returned. The trigger should execute as a BEFORE trigger when the
DETAIL_RETURNDATE or DETAIL_DUEDATE attributes are updated. The trigger should satisfy
the following conditions.
a) If the return date is null, then the days late should also be null.
b) If the return date is after the due date, then the video is considered late so the number
of days late must be calculated and stored (the number of days late =
DETAIL_RETURNDATE - DETAIL_DUEDATE).
c) Test your trigger.
