Getting data from CI db query

1. All result set

$query = $this->db->query("YOUR QUERY");

if ($query->num_rows() > 0)
{
   foreach ($query->result() as $row)
   {
      echo $row->title;
      echo $row->name;
      echo $row->body;
   }
}

2. Just one row

$query = $this->db->query("YOUR QUERY");

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

   echo $row->title;
   echo $row->name;
   echo $row->body;
}
