Codeigniter Clone Data from table and update it

问题

What i am trying to do:
Try to Clone Data (Update) from Table "Payment" to "Payment History"

Payment Table

Payment_ID
Payment_Amount
Payment_Method
Payment_Remark

Payment History Table

Payment_ID
PaymentHistory_ID
Payment_Amount
Payment_Method
Payment_Remark

Both have the same column and same data type

My Code: Controller

    public function updateHistory($Payment_ID){

  $this->db->select('*'); 
  $this->db->from('Payment');   
  $this->db->where('Payment_ID', $Payment_ID); 
$query = $this->db->get();
    $this->db->update('PaymentHistory',$query);

}

You can do like this:

$query = $this->db->where('Payment_ID', $Payment_ID)->get('Payment');
foreach ($query->result() as $row) {      
      $this->db->where('Payment_ID', $row->Payment_ID)->update('PaymentHistory', $row); // To update existing record
      //$this->db->insert('PaymentHistory',$row); // To insert new record
}
