CodeIgniter - return only one row?

Question

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-         


        

Answer 1

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.

Answer 2

You can do like this

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

return $q->campaign_id;

Documentation : http://www.codeigniter.com/user_guide/database/results.html

Answer 3

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

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

Answer 4

We can get a single using limit in query

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

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

Answer 5

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();

Answer 6

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.
