WHERE PUBLISHER.PUBLISHER_CODE = BOOK.PUBLISHER_CODE 
ORDER BY PUBLISHER_NAME;
#12

FROM BOOK, PUBLISHER 
WHERE PUBLISHER_NAME = 'Plume' 
AND BOOK.PUBLISHER_CODE = PUBLISHER.PUBLISHER_CODE;
#13
SELECT BOOK_CODE, TITLE, PRICE 
FROM BOOK, PUBLISHER 
WHERE PUBLISHER_NAME = 'Plume'

It would help if you noted which ones were causing an issue. Have you used or die(mysqli_error()) or the mysql equivalent - whichever you're using to find the error yourself?

oh, each one of those were causing an issue because they had a syntax issue... i wrote about 30 queries for the assignment but those were the few that had syntax issues that i am not understanding.

whichever you're using to find the error yourself?

The teacher's compiler is indicating that those had errors.

on all of these it says that (in the error):
Table 'jstudent0.BOOK' doesn't exist

0

That says, I believe, that in the database jstudent0, the table BOOK doesn't exist.

Are you sure that's the table name? Is it BOOKS?
