title: which is faster? Statement or PreparedStatement
body: <p>Often, in the network can be found code like this:</p>
  
  <pre><code>private static final String SQL = "SELECT * FROM table_name";
  ....
  </code></pre>
  
  <p>and for this SQL query is used PreparedStatement. Why?<br>
  As i know, PreparedStatement spend time to precompile SQL statement.  It turns out so that the Statement is faster than a PreparedStatement. Or I'm mistaken?</p>
