Create a trigger called Trig_Enroll_BI on the ENROLLMENT table that fires before an INSERT statement. The trigger must generate a proper error message if the student id or section id or both invalid. Test your code for all possible options. Make sure that all columns that have NOT NULL values (Use system date for all date fields, user id for all created and modified by fields). Display the inserted record from the ENROLLMENT table after a successful enrollment transaction.
