title: Is it possible to load doctrine fixtures without deleting database
body: <p>I have defined some <code>fixtures</code> in <code>doctrine</code>.</p>
  
  <p>When i try to run using this</p>
  
  <p><code>php app/console doctrine:fixtures:load</code> then it asks me to purge the database.</p>
  
  <p>is it possible to load it without purging database.</p>
  
  <p>I remeber <code>Django</code> has <code>fixtures</code> which can be loaded in separate tables without purging existing database</p>
