In Your Turn 2-23 on page 64, would you get the same result if
you performed the PROJECT command before the JOIN command? Why or
why not?
Homework Answers
Answer is YES.
Project command limit the the output results based on filter we pass. When we use project command before join results will get filtered and filtered results will pass to join which means there will be no change. If project command passes after join then answer is No. Because you are filter after join condition.
