title: Query to get third highest marks
body: <p>I have a student_table table with two columns student_name(with uniqe constraint),student_marks.  From this table, I need to get the record of the student who has the 3rd highest marks.</p>
  
  <p>I tried this, but it's incorrect:</p>
  
  <pre><code>select * from student_table orderby(marks) enum(marks)=3;
  </code></pre>
  
  <p>How do I correct this query?</p>
