title: Error: 1031 SQLSTATE: HY000 (ER_ILLEGAL_HA) - Meaning?
body: <p>What does this error mean?</p>
  
  <p><strong><code>MYSQL - Error: 1031 SQLSTATE: HY000 (ER_ILLEGAL_HA)</code></strong> </p>
  
  <p>I can find a million references on the MySQL site to this error - but can not find the definition for it.</p>
  
  <ul>
  <li>Anyone know the definition? Meaning?</li>
  <li>Or a good place to reference these errors?</li>
  </ul>
  
  <p>I have been exporting a database from a production area - and importing to a development testing area, for over a year now. And have used the same selections on export/import every time. Today, it reports this error on a <strong>INSERT DELAYED INTO</strong> command during import.</p>
  
  <p>I have selected a transaction with, <strong>Add DROP TABLE, Add IF NOT EXISTS, Add AUTO_INCREMENT value, Complete inserts, Extended inserts, Use delayed inserts</strong> on my my exports. Because I want to ensure the copy I place in the development database, is overwritten and that creates an exact copy of the development database.</p>
  
  <p>I would love to know why after a year it now reports this error - and a good place to look the meaning of these errors up.</p>
  
  <p>Thank you.</p>
  
  <p>Regards.</p>
