title: Query using group_concat is returning only one row
body: <p>This is a query that is supposed to get the user's information, their project's information, and a group_concat of all the image paths that such project is associated to. To add to this, I am only getting the information mentioned from the people the user is following.</p>
  
  <p>This is, however, <strong>only retunring one row.</strong></p>
  
  <pre><code>SELECT users.first_name, users.last_name, users.user_id, projects.project_id, projects.project_name, projects.project_time, group_concat(images.image_path)
  FROM users, projects, images
  WHERE users.user_id = projects.user_id
  AND users.user_id IN (SELECT follow_user_2 FROM following WHERE follow_user_1 = 1)
   ORDER BY projects.project_id DESC
  </code></pre>
  
  <p><strong>TO COMPARE:</strong> The following query <strong>WORKS</strong> in the sense that in the loop it gives all of the user's information and the projects information related to such user.</p>
  
  <pre><code>SELECT users.first_name, users.last_name, users.user_id, projects.project_id, projects.project_name, projects.project_time 
      FROM users, projects
      WHERE users.user_id = projects.user_id 
      AND users.user_id IN (SELECT follow_user_2 FROM following WHERE follow_user_1 = 1)
      ORDER BY projects.project_id DESC
  </code></pre>
  
  <p>When I try to use group_concat it just returns me <strong>one</strong> row and I do not understand why.</p>
  
  <p>Can someone help me please? Thank you. If my question was not clear enough, I will elaborate.</p>
  
  <p>If this helps, here's an SQL FIDDLE.

  I had to shorten my schema a lot. Try both queries to above to see the problem.</p>
