But when I am using the

return $query->row();

I am getting only one row.How can I get all the rows.I dont get any idea in this article

Answer 1

instead of this

$query->row();

use this

foreach ($query->result() as $row)
{
    echo $row->field_name;
    //use the database table fields name in the place of field_name property
}
