Question: great, I also need to know the first name of each instructor with the course name, and where their office is located.
SQL: SELECT T2.emp_fname ,  T4.prof_office ,  T3.crs_description FROM CLASS AS T1 JOIN employee AS T2 ON T1.prof_num   =   T2.emp_num JOIN course AS T3 ON T1.crs_code   =   T3.crs_code JOIN professor AS T4 ON T2.emp_num   =   T4.emp_num
