CI - MySQL - Last Insert ID ?

[eluser]cPage[/eluser]
Is there a way to get the last insert id in a table. Some kind of :

Code:

$this->db->get_last_insert_id();

CI has a built in function to handle this!

Code:

$this->db->insert_id();

However, i found out that it could be used only one time. If you want to save the value for a while put the result into a variable.

Code:

$last_insert_id = $this->db->insert_id()

Or for a permanent access to the last row you can do this in a model. (e.g invoice_model)

Code:

function last_invoice()
{
  $int = $this->db->count_all('invoice');
  $query = $this->db->get('invoice',1,$int-1);
  return $query->row()->id_invoice;
}

Thanks for the help its appreciate.
