Lab 13
To perform the following assignments, refer to the tables in the JustLee Books database.
1. Create a view that lists the name and phone number of the contact person at each publisher. Don’t include the publisher’s ID in the view. Name the view CONTACT.
2. Change the CONTACT view so that no users can accidentally perform DML operations on the view.
CREATE OR REPLACE VIEW CONTACT
AS SELECT name, phone FROM publisher
WITH READ ONLY
3. Create a view called HOMEWORK13 that includes the columns named Col1 and Col2 from the
FIRSTATTEMPT table. Make sure the view is created even if the FIRSTATTEMPT table doesn’t exist.
CREATE VIEW homework13
AS SELECT Col1, Col2
FROM firstattempt
4. Attempt to view the structure of the HOMEWORK13 view.
