Gracias me fue de mucha ayuda.
aca dejo el ejemplo como lo termine:
Código PHP:
Ver original<?php
class Application_Model_DbTable_Projects extends Zend_Db_Table_Abstract{
protected $_name = 'projects';
public function listProject($id){
$select = $this->select()
->from(array('p' => 'projects')) ->join(array('pm' => 'permissions'),'p.Id_Permission = pm.Id_Permission', array('Name_Permission'=>'Description')) ->join(array('l' => 'languages'), 'p.Id_Language = l.Id_Language',array('Name_Language')) ->where('p.Id_User_Project = '.(int)$id)
->where('p.State_Project = 1')
->where('pm.State_Permission = 1')
->where('l.State_Language = 1');
$select->setIntegrityCheck(false);
return $select->query()->fetchAll();;
}
public function AddProject(){
}
}
