zend_db_select use with zend_db_table_abstract

I'm not sure how to do this: My Post model is extending Zend_Db_Table_Abstract and I'm working on my homepage right now, where I want to show every post from the DB. The documentation says that fetchAll() and fetchRow are deprecated, and that I should use Zend_Db_Select. I've read through the manual, but I don't really se开发者_如何学Pythone how this is used in combination with Zend_Db_Table_Abstract? Or do I just make an instance and start writing queries 'out of nowhere'? Because I'd like to acces my data through my Model...

Am I missing something?

They are not deprecated, the use on them is the one that changed, for example, before you could pass a where clause and a order clause, the correct way to do that is use a Select:

public function getNewOrdersByDate()
{
     $Select = $this->select();
     $Select->where('status=?', 'new')->order('created ASC');

     return $this->fetchAll($Select);
}
