title: Can I set the Database adapter to use permanently from within a Zend_Db_Table_Abstract Class?
body: <p>I have 2 databases that my site uses including a central user database that relates to other site-specific databases. </p>
  
  <p>Sometimes it is adequate to call <code>new User(array('db'=&gt;'adapter1'));</code> (but never convenient); other times, though, such as when declaring relationships between tables on different databases, there is no way to do this. </p>
  
  <p>Does anyone know a way to specify which database adapter to use from within the Zend_Db_Table_Abstract class?</p>
  
  <p>Thanks!</p>
