title: Inserting int value into sqlite using (FMDB with iOS) and retrieving it: not what we would be waiting for
body: <p>I am a little embarrassed since I spend my whole day on this trouble while it could seems really trivial for you,</p>
  
  <p>As mentioned in the title, I am storing values in a sqlite via FMDB (these values are 1, 2 or 3 in this case).</p>
  
  <p>When in another view, I am connecting to the SQLiteDB and retrieving my value, it display to me a strange number (usually in the order of 144963008) which does not correspond to the value I stored.</p>
  
  <p>Using NSLog() I can see that the value stored are the value I want to store.</p>
  
  <pre><code>2014-01-06 12:14:16.677 GDV[11314:70b] the inserted value in column 'idValue' is: 1
