I need to check if that argument date is before a year ago. If that is the case, I have to "purge" all of the tables related to "schedules" there are 2 of them. So for example, say the user types , my procedure has to compare it with SYSDATE - 1 year in that case, it would be Since the value is less than today minus a year, the tables "MovieSchedule" and "ChannelSchedule" have to be purged.
