title: select column as true / false if id is exists in another table
body: <p>I have 2 tables, one for members and another one for their services.
  Those are InnoDB tables on MySQL 5.6 server.</p>
  
  <p>Members table:</p>
  
  <pre><code>id     |       name       |   phone
  ----------------------------------------
    1       Daniel             123456789
    2       Liam               123456789
    3       Lucas              123456789
  </code></pre>
  
  <p>Services table:</p>
  
  <pre><code> MID    |    profile    |     lastSeen
  ----------------------------------------
    1       2                  2014-08-13 14:23:23
    3       1                  2014-08-12 15:29:11
  </code></pre>
  
  <p>I try to achieve this result:</p>
  
  <pre><code> id     | name      | services
  ---------------------------------
    1       Daniel      true
    2       Liam        false
    3       Lucas       true
  </code></pre>
  
  <p>So if the user ID is exists in services table, the column services will be true or false otherwise.</p>
  
  <p>I tried to do it with JOINs and Sub-Queries without success, so I need your help ;)</p>
