CodeIgniter: How To Do a Select (Distinct Fieldname) MySQL Query
$record = '123';$this->db->distinct();$this->db->select('accessid');$this->db->where('record', $record); $query = $this->db->get('accesslog');then
$query->num_rows();should go a long way towards it.
try it out with the following code
function fun1() { $this->db->select('count(DISTINCT(accessid))'); $this->db->from('accesslog'); $this->db->where('record =','123'); $query=$this->db->get(); return $query->num_rows(); }
You can also run ->select('DISTINCT `field`', FALSE) and the second parameter tells CI not to escape the first argument.
With the second parameter as false, the output would be SELECT DISTINCT `field` instead of without the second parameter, SELECT `DISTINCT` `field`
