Exercise 2 Solution
First, remove Bob Robson’s details from the database. His member details are stored in the
MemberDetails table, and his favorite film categories are in the FavCategory table. Each record in the
FavCategory table contains only the MemberId and the CategoryId. Remember from Chapter 1 that the
MemberId field in this table is a foreign key; its value is referenced from the MemberDetails table, where
it’s a primary key. Therefore, you must delete the records from the FavCategory and Attendance tables
first:
DELETE FROM FavCategory WHERE MemberId = 2;
DELETE FROM Attendance WHERE MemberId = 2;
Once you delete Bob from the FavCategory table, you can delete him from the MemberDetails table:
DELETE FROM MemberDetails WHERE MemberId = 2;
Exercise 3 Solution

Update the database to reflect the Orange Town boundary changes. You need to change the City field
from Orange Town to Big City where the street is Long Lane and the city is Orange Town.
Remember that there is also a Long Lane in Windy Village, so you can’t just check the street name. You
need to update only if the street is in Orange Town:
UPDATE MemberDetails SET City = ‘Big City’
WHERE Street = ‘Long Lane’ AND City = ‘Orange Town’;
