title: How to Stop Row Returning Twice MYSQL
body: <p>I have a database setup like this:</p>
  
  <pre>Table: Sections
  <b>section_id</b> | <b>section_name</b>
    i23kj    |    News 
    o492q    |   Events
  
  Table: Subsections
  <b>sub_section_id</b> | <b>section_id</b> | <b>sub_section_name</b> 
      q123l      |   i23kj    | Washington Post
      z765a      |   i23kj    |    NY Times
      w439m      |   o492q    |   Launch Party  
  </pre>
  
  <p>I want a page to print the following information:</p>
  
  <pre>
  <b>News</b>
  Washington Post
  Ny Times
  
  <b>Events</b>
  Launch Party
  </pre>
  
  <p>I'm using the query:</p>
  
  <pre><code>SELECT Sections.section_id, Sections.section_name, Subsections.sub_section_id, Subsections.sub_section_name 
  FROM Sections INNER JOIN Subsections 
  ON Sections.section_id=Subsections.section_id
  </code></pre>
  
  <p>However this returns:</p>
  
  <pre>
  <b>News</b>
  Washington Post
  
  <b>News</b>
  Ny Times
  
  <b>Events</b>
  Launch Party
  </pre>
  
  <p>How can I change my query to only display the Section once and the Subsections under that section </p>
