Nested DB transactions

[eluser]Unknown[/eluser]
Hi!

In model1 i start transaction and in the middle of it I call method from otherModel which also has transaction. Do those 2 nested transactions count as one?

Code:

-load someModel
$this->db->trans_start();

     $this->db->query('come query');

    
     -call some function from someModel which has another transaction start and complete in it

$this->db->trans_complete();

And sorry for my poor English please!
