Quées lo mínimoqueestamosbuscando?

$clist = Doctrine::getTable("Country")
->createQuery()
->select({fields})
->execute({strategy});

$conn = Doctrine_Manager::connection();
$data = $conn->execute("select * from countries")->fetchAll();

Para que
quiero el ORM?
$conn= Doctrine_Manager::connection();
Para manejarlasconexiones!

Doctrine?
Unainteresanteparadoja!

Ejemplo!

UserTable::getInstance()
->createQuery()
->select ("id, name, surname, age")
->where("is_deleted = ?", false)
->andWhere("is_closed = ? ", false)
->andWhere(”age > ? ", 50 )
->execute( array(),
Doctrine_Core::HYDRATE_ARRAY);
UserTable::getInstance()
->createQuery()
->select ("id, name, surname, age")
->where("is_deleted = ?", false)
->andWhere("is_closed = ? ", false)
->andWhere(”age > ? ", 50 )
->execute( );
