Zend DB atomic transactions

I have to perform a group of SQL operations that either survive together or die together. So that if any part of my statement/s fail, the entire process is rolled back to the beginning as if the transaction never took place.

without zend I would do:

$conn->query('BEGIN');
$conn->query($myQuery);
//rollback if anything went wrong
$conn->query('COMMIT'); 

In Zend I created the Db connection in my bootstrap:

    protected function _initDb()
{
    $config=Zend_registry::get('config');
    $db = Zend_Db::factory($config->resources->db->adapter, $config->resources->db->params);  
    //set default adapter         
    Zend_Db_Table_Abstract::setDefaultAdapter($db); 
    Zend_Registry::s开发者_Python百科et("db", $db);  
}

And interactions with Db are made by models classes (extending Zend_Db_Table_abstract)

class Platform extends Zend_Db_Table_Abstract
{
 public function insertPlatform($x)
 {
  $this->insert($x);
 }
}
class Game extends Zend_Db_Table_Abstract
{
 public function insertGame($x)
 {
  $this->insert($x);
 }
}

How could I achieve the same (survive together or die together)in Zend?

thanks

Zend_Db wraps the transaction functionality too. So there is nothing different in using it with or without ZF.

You find ZF transactions explained in the Adapter Section of the Zend_Db Manual. Look for the paragraph 'Controlling Database Transactions'.
