COUNT / GROUP BY with active record?

Question

I have a table with the following info:

id  |  user_id  |  points
--------------------------
1   |  12       |  48
2   |  15       |  36
3   |  18       |  2         


        

Answer 1

This code counts rows with date range:

Controller:

$this->load->model("YourModelName");
$data ['query'] = $this->YourModelName->get_report();

Model:

  public function get_report()
     {   
       $query = $this->db->query("SELECT  *
FROM   reservation WHERE arvdate <= '2016-7-20' AND  dptrdate >= '2016-10-25' ");
       return $query;
     }

where 'arvdate' and 'dptrdate' are two dates on database and 'reservation' is the table name.

View:

num_rows();
?>

This code is to return number of rows. To return table data, then use

$query->rows();
return $row->table_column_name;
