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. .
