There are two tables:
table "enrolled":
SIDN SECT CREDITS
----- ----- ---------
11111 B411 2
22222 B332 3
11111 B412 3
22222 B412 4
33333 B412 3
Table "student":
SIDN MAJO NAME
----- ---- -------------
11111 PHIL King, Patrick
22222 CSCI Winn, William
33333 ENGR Smith, John
How to list all students' names, how many classes,
and how many credit hours they are taking?

Chen,
Select s.Name as Name,
count(e.Sect) as numberOfClasses,
sum(e.Credits) as totalCredits
From student s,
enrolled e
Where e.SIDN = s.SIDN
Group by s.name
Result:
Name numberOfClasses totalCredits
-------------------- --------------- ------------
King, Patrick 2 5
Smith, John 1 3
Winn, William 2 7
I hope this is what you were looking for.
