Answer 1

Answer:

1.

a) To select from BOOK:

GRANT SELECT ON BOOK TO Kwame

b) To update in BOOK:

GRANT UPDATE (BK_LIST_PRICE) ON BOOK TO Kwame

2. In this case, we will first need to create a view as below:

CREATE VIEW BOOK_PBID_217 AS SELECT * FROM BOOK WHERE PBID = 217

a) To select where PBID = 217:

GRANT SELECT ON BOOK_PBID_217 TO Kwame

b) To update in BOOK:

GRANT UPDATE (BK_LIST_PRICE) ON BOOK_PBID_217 TO Kwame

3.

CREATE VIEW AUTHOR_2K13 AS SELECT AU_NAME,AU_DOB FROM AUTHOR WHERE AU_DOB < DATE '2013-01-01'

4.

CREATE VIEW PUBLISHER_Z23285_5 AS SELECT PBID,PB_NAME,PB_STREET,PB_ZIPCODE,PB_PHONE FROM PUBLISHER WHERE PB_ZIPCODE = 23284 OR PB_ZIPCODE = 23285

5.

CREATE VIEW PUBLISHER_BK_Z23285_5 AS SELECT BKID, BK_TITLE, BK_LIST_PRICE, PBID,PB_NAME FROM BOOK,PUBLISHER WHERE BOOK.PBID = PUBLISHER.PBID AND BK_LIST_PRICE < 250.00 AND (PB_ZIPCODE = 23284 OR PB_ZIPCODE = 23285)
