update in codeigniter query code example

Example 1: update in codeigniter query

$data = array(
        'title' => $title,
        'name' => $name,
        'date' => $date
);

$this->db->where('id', $id);
$this->db->update('mytable', $data);

//
//      UPDATE mytable
//      SET title = '{$title}', name = '{$name}', date = '{$date}'
//      WHERE id = $id

Example 2: codeigniter where order by

$this->db->select('ae_users.employee_id, ae_users.emp_name, ae_users.emp_name2, ae_users.emp_name3');
		$this->db->from('ae_users');                
		$this->db->where_in('ae_users.employee_id',$employee_ids);
                $this->db->_protect_identifiers = FALSE; // stop CI adding backticks
                $order = sprintf('FIELD(ae_users.employee_id, %s)', implode(', ', $employee_ids));
                $this->db->order_by($order);
                $this->db->_protect_identifiers = TRUE; 
		$query =$this->db->get();
               // echo '<pre>'; print_r($this->db->last_query());exit;
		if ($query->num_rows()) {
			return $query->result_array();
		} else {
			return 0;
		}

Example 3: codeigniter update query return value

public function update_row(){
		
		$update_rows = array(
			'name' => 'rincky',
			'address' => 'India',

		);
		$this->db->where('id', 1 );
		$result = $this->db->update('user', $update_rows);	
		return $result;
