And what about the course code that they are enrolled in?
SELECT T3.CRS_CODE FROM CLASS AS T1 JOIN enroll AS T2 ON T1.class_code   =   T2.class_code JOIN course AS T3 ON T1.crs_code   =   T3.crs_code JOIN department AS T4 ON T3.dept_code   =   T4.dept_code WHERE T4.dept_name   =   'Accounting'
course code they are enrolled in refers to CRS_CODE from course table; enrolled in a course within a specific department requires joining tables that include class, enroll, course, and department based on respective keys and filtering on the specified department's name.
