title: Sql where value is different from it
body: <p>Sorry, I didn't find any answer on internet.</p>
  
  <p>My postgresql query look like this :</p>
  
  <pre><code>SELECT distinct intervalle, inter_begin, inter_end 
  FROM mytable 
  WHERE inter_end != inter_begin
  </code></pre>
  
  <p>I want to select information when inter_end (timestamp) is different of inter_begin (timestamp too), because i have some result with same timestamp at the beginning and the end.
  But with this query result I have the same timestamp for inter_begin and inter_end in my result and i don't want to.</p>
  
  <p>So is it possible to do that? And if yes, how?</p>
  
  <p>Thank you !</p>
