A sample transcript of a student’s grades:
SELECT s.name AS 'Student Name', coursename AS 'Course Name', (CONVERT(varchar(10),
semesteryear, 1) + semestercode) AS 'Term', grade AS 'Grade', credithours AS 'Credit Hours'
FROM StudentClasses sc
JOIN Students s ON sc.stud_id = s.stud_id

A query to find out which students are enrolled in a particular class:
SELECT s.name AS 'Student Name'
FROM StudentClasses sc
JOIN Students s ON sc.stud_id = s.stud_id
WHERE sc.sect_id = 100001;
