title: Why this SQL query returns extra space?
body: <p>I am trying to undestand why the below query is returning extra space after '3'. This is a screenshot from on of the SQL quizes available online. I would expect 'C' to be the correct answer.  Is there anything that causes the extra space or might it be an error in the task?</p>
