title: PreparedStatement setNull(..)
body: <p>Java PreparedStatement provides a possibility to explicitely set a Null value. This possibility is:</p>
  
  <pre><code>prepStmt.setNull(parameterIndex, Types.VARCHAR);
  </code></pre>
  
  <p>Are the semantics of this call the same as when using a specific setType with a null parameter?</p>
  
  <pre><code>prepStmt.setString(null);
  </code></pre>
  
  <p>?</p>
