At the moment if I am doing a query on the database that should only return one row, using:

...query stuff...
$query = $this->db->get();
$ret = $query->result();
return $ret[0]->campaign_id;

Is there a CodeIgniter function to return the first row? something like $query->row();

Or even better would be the ability to, if there was only one row, to just use the query object directly.

e.g. $query->campaign_id;

You've just answered your own question :) You can do something like this:

$query = $this->db->get();
$ret = $query->row();
return $ret->campaign_id;

You can read more about it here: http://www.codeigniter.com/user_guide/database/results.html

This is better way as it gives you result in a single line:

$this->db->query("Your query")->row()->campaign_id;

To add on to what Alisson said you could check to see if a row is returned.

// Query stuff ...
$query = $this->db->get();

if ($query->num_rows() > 0)
{
    $row = $query->row(); 
    return $row->campaign_id;
}

return null; // or whatever value you want to return for no rows found

To make the code clear that you are intending to get the first row, CodeIgniter now allows you to use:

if ($query->num_rows() > 0) {
    return $query->first_row();
}

To retrieve the first row.

If you require to get only one record from database table using codeigniter query then you can do it using row(). we can easily return one row from database in codeigniter.

$data = $this->db->get("items")->row();

Change only in two line and you are getting actually what you want.

$query = $this->db->get();
$ret = $query->row();
return $ret->campaign_id;

try it.

We can get a single using limit in query

$query = $this->db->get_where('mytable', array('id' => $id), $limit, $offset);

You can do like this

$q  = $this->db->get()->row();

return $q->campaign_id;

Option 1 $limit = 1 $offset = 0

$query = $this->db->get_where('items', array('id' => $id), $limit, $offset);

Option 2

$this->db->get("items")->row();

  • I don't know why it got a minus score. But I just realized something crazy. Option 1 (limit) is faster than Option 2 (row). Since Option 2 will retrieve all results and get the first row. – Kosmas Jan 07 '23 at 18:34

class receipt_model extends CI_Model {

   public function index(){

      $this->db->select('*');

      $this->db->from('donor_details');

      $this->db->order_by('donor_id','desc');

      $query=$this->db->get();

      $row=$query->row();

      return $row;
 }

}
