Doctrine - insert multiple rows with just one save()

Question

How do I insert multiple rows into table calling save() method once in Doctrine?

Answer 1

I took a look into the code of the "save" method of the Doctrine (1.2.x) "Collection.php" and all I saw is something like this:

foreach ($this->getData() as $key => $record) {
   $record->save($conn);
}

How should this ever insert all records with one mysql INSERT?
