I entered:
SELECT Name
FROM STUDENT AS ST, COURSE AS C, SECTION AS SE, GRADE_REPORT AS G
WHERE ST.Student_number=G.Student_number AND
G.Section_identifier=SE.Section_identifier AND
Instructor='Anderson'
and am expecting to get back two names, but I get four of each name. I do not know why I don't get one of each since each person is taking the instructor Anderson only once.
