symfony doctrine将实体对象移动到另一个实体类型

Is there any way to move a row to another mysql table with Doctrine?

I am searching for the equivalent of the following mysql:

INSERT myTableCopy (
   SELECT * FROM myTable WHERE id = 2

I expect something like this:

// $first is an object from  myTable
$this->getDoctrine()->getRepository('MyBundle:MyTable')->findOneBy(array('id' => 2));
$second = new myTableCopy();
$second = clone $first;

Unfortunately (but logically), the $second entity is of type myTable...

How can I do this?

I know I can use prepare statement, but I want to know if I can do this with one of the Doctrine function.

FYI: I have a huge table (several millions of rows), and I want to move old data to a "backup table" that would not be so used

PS: I know that this thread is proposing the following solution, but I think that there should be a better way with serializer/normalizer...

 // now loop over the properties of each post array...
    foreach ($post as $property => $value) {
        // create a setter
        $method = sprintf('set%s', ucwords($property)); // or you can cheat and omit ucwords() because PHP method calls are case insensitive
        // use the method as a variable variable to set your value

    I finally found the error after reading this post from @Colin M.

    Here is the final solution of my problem:

    $myOriginalObject = $this->getDoctrine()->getRepository('MyBundle:MyTable')->findOneBy(array('id' => 2));
    // Here modify the original object if needed...
    $myTableCopyObject = new myTableCopy();
    $oldReflection = new \ReflectionObject($myOriginalObject);
    $newReflection = new \ReflectionObject($myTableCopyObject);
    foreach ($oldReflection->getProperties() as $property) {
        if ($newReflection->hasProperty($property->getName())) {
            $newProperty = $newReflection->getProperty($property->getName());
            $newProperty->setValue($myTableCopyObject, $property->getValue($doi_tmp));

    NB: only the ID seem to not be conserved when you have an auto-increment ID
