Question

Does doctrine 2 support some kind of
“select into”-syntax?

In pure MySQL it would be something like this:

INSERT INTO tbl_temp2 (fld_id)
  SELECT tbl_temp1.fld_order_id
  FROM tbl_temp1 WHERE tbl_temp1.fld_order_id > 100;

I checked the manual, yet without sucess.

Answer 1

I am refering to Doctrine in version 2.3.1:
In this version you can get the current connection to the database from ORM/EntityManager.
There is only one connection (this was different in Doctrine 1).
Here is what worked for me for the insert-select-task:

$db = $this->_em->getConnection();
$query = "INSERT INTO table2 (myfield) SELECT table1.myfield FROM table1 WHERE table1.id < 1000";
$stmt = $db->prepare($query);
$params = array();
$stmt->execute($params);
