The textbook the problem refers to is Database System Concepts, Sixth Edition by Avi Silberschatz, Henry F. Korth, S. Sudarshan. I need the commands to enter for B. I tried inputting: UPDATE INSTRUCTOR SET SALARY = 10000 * (select count(course_id) from instructor natural left outer join teaches); Instructors have an ID, courses have an ID, teaches is what keeps the data of who teaches the course and when it is offered. Into myphpadmin. I get some sort of error due to instructor being put beside UPDATE and from. Is this the right way to get everyone an update salary as well?
