Here's the situation:

Table: class  Columns: name, id (both VARCHAR)
Table: student - Columns: name, id (both VARCHAR)
Table link - Columns: pid, cid (both VARCHAR) This table links
students and classes

What I'm still after is only students in a specific set of classes.
For example - A & B. (A recordset containing only Narinder and Norman
is what i'd want - They are the only two students who are in both
classes A & B) I've tried various forms of GROUP BY and COUNT, but I
haven't been able to get any results.

select * from student where id in ( select id from class where class.id = "A") AND id in ( select id from class where class.id = "B") _______________________________________________
