  1. So here is the question you
    were asked to answer, and
  2. here is one possible answer.
  3. Select name from animals where
    species equals llama, and
  4. birthdate is greater than or equal to
    the beginning of 1995, January 1, 1995.
  5. And birthdate is less than or
    equal to December 31, 1998.
  6. So, just as when you did this manually,
    your query should have found one llama,
  7. Allison the llama.
  8. Now we can have the database
    find our llamas for us,
  9. instead of doing it by hand.
  10. This is a pretty big help if we
    have lots and lots of llamas.
