I bet if you read over your notes or your textbook you'll find that your instructor explained how to do this sometime during your instruction. But without knowing what you instructor intended you to do we might be able to take some guesses. If you could list every row of the tables in your query you could look down them yourself and see what you think the result of the query should be. So you can do that, just use SELECT * FROM dbo.employees Obviously in real life tables get huge and it's not practical to do this. That's why when you test your code you make up small dummy tables to check that things are working correctly. And you make up appropriate sample data to test two kinds of errors: false positive: returning a row you didn't mean to return false negative: not returning a row you should have returned Good luck with your course.
