Instructions:
SQL statements either work or fail; and one description is
correct or one reason for failure triggers an error. You should
practice with the practice final exam's two questions to
understand how this exam will work.
You can't backup to refer to prior questions, as such it works
like a certification test. Once answered each question is
unavailable. So, don't skip questions. There are no typos, don't
assume a typo when answering the questions.
You have only 60 minutes to take the test and you only have
one attempt.
