title: MySQL - default value for TIMESTAMP(3)
body: <p>My database is MySql 5.6.</p>
  
  <p>I want to use CURRENT_TIMESTAMP as the default value an attribute which is type of TIMESTAMP(3). </p>
  
  <p>But I get the error:</p>
  
  <blockquote>
    <p>ERROR 1067 (42000): Invalid default value for 'updated'</p>
  </blockquote>
  
  <p>I think it is because <code>CURRENT_TIMESTAMP</code> is only in precision of second. </p>
  
  <p>How can I set current time as the default value for a <code>timestamp</code> with fractional part?</p>
