1) SELECT * FROM AUTHOR WHERE AU_DOB > 'JANUARY-18-1976';
2) SELECT AU_NAME, AU_DOB FROM AUTHOR;
3) SELECT AU_NAME, AU_DOB FROM AUTHOR WHERE AU_DOB > 'JANUARY-18-1976';
4) SELECT B.BK_TITLE, B.BK_LIST_PRICE, P.PB_NAME FROM BOOK B, PUBLISHER P WHERE B.PBID = P.PBID;
5) SELECT B.BK_TITLE, B.BK_LIST_PRICE, P.PB_NAME FROM BOOK B, PUBLISHER P WHERE B.PBID = P.PBID AND B.BK_LIST_PRICE > 200.00;
6) SELECT B.BK_TITLE, B.BK_LIST_PRICE, A.AU_NAME,P.PB_NAME FROM BOOK B, BOOK_AUTHORS BA, PUBLISHER P, AUTHOR A WHERE B.PBID = P.PBID AND B.BK_LIST_PRICE > 200.00;
7) SELECT P.PBID,P.PB_NAME,Z.ZIPCODE,Z.CITY.Z.STATE FROM PUBLISHER P, ZIPCODE Z,BOOK WHERE P.ZIPCODE = Z.ZIPCODE AND BOOK.BK_PRICE_LIST >200.00;
8) SELECT COUNT(8), MIN(BK_LIST_PRICE), AVG(BK_LIST_PRICE), MAX(BK_LIST_PRICE) FROM BOOK;
9) SELECT P.PB_NAME, AVG(BK_LIST_PRICE), MAX(BK_LIST_PRICE) FROM BOOK, PUBLISHER P WHERE BOOK.PBID = P.PBID;
10) SELECT COUNT(*) FROM PUBLISHER P, BOOK B WHERE P.PBID = B.PBID AND B.BK_LIST_PRICE > 200.00;
11) SELECT P.PBID, P.PB_NAME FROM PUBLISHER P, BOOK B WHERE P.PBID = B.PBID AND B.BK_LIST_PRICE < 200.00;
12) SELECT P.PBID, P.PB_NAME FROM PUBLISHER P, BOOK B WHERE P.PBID = B.PBID AND B.BK_LIST_PRICE > 200.00;
