Question

I want to get the maximum id of row data. In my table first column is id then firstname and etc.
this is the sql command I used to get the max(id) of row data.

<?PHP  $maxid=$this->db->query("SELECT MAX(id) FROM `emplyee_personal_details`");
                print_r( $maxid) ;?>

but it prints bunch of data as it is a array. But I need only the maximam id of row data for validation before data inserting and updating.

How to get the maxid. I use codeigniter framework.

Answer 1

Try this:

$maxid = $this->db->query('SELECT MAX(id) AS `maxid` FROM `emplyee_personal_details`')->row()->maxid;

UPDATE

This will work even if your table is empty (unlike my example above):

$maxid = 0;
$row = $this->db->query('SELECT MAX(id) AS `maxid` FROM `emplyee_personal_details`')->row();
if ($row) {
    $maxid = $row->maxid; 
}
