Yes, the first names of all instructors who teach courses,
select t2.emp_fname 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
Great. I need to know which first name of the instructor goes with each class and class description.
select t2.emp_fname, 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
great, I also need to know the first name of each instructor with the course name, and where their office is located.
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
