title: Insert row from table in another database
body: <p>Is it possible to INSERT...ON DUPLICATE KEY UPDATE into a table on the current database from a table on another database?</p>
  
  <p>The remote table has 3 additional columns which will need to be ignored (so can't do SELECT *).</p>
  
  <p>Also, is it possible to do multiple rows in one query?</p>
  
  <p>Thanks.</p>
