title: PL SQL Update working in one window but when I try to fetch the record back it hasn't changed
body: <p>So in PLSQL Developer:</p>
  
  <pre><code>   UPDATE someTable t
     SET animals      = 'hamsters'
     WHERE t.someIdentifier = 'XXXX';
  SELECT * 
  FROM someTable t  
  WHERE t.someIdentifer = 'XXXX';
  </code></pre>
  
  <p>appears to work as the select query in the final line does indeed confirm that animals has been set to equal the value 'hamsters'.</p>
  
  <p>However, when I run the select query on it's own,</p>
  
  <pre><code>select * from someTable t  WHERE t.someIdentifier = 'XXXX';
  </code></pre>
  
  <p>animals doesn't seem to have updated. Any general pointers as to where this problem might be coming from would be appreciated. </p>
