[eluser]RaviDalal[/eluser]
I am writing following codeigntier function using which i want to fetch distinct record for contact_type field..........
function getdetaildatabyid($id)
{
$this->db->select("contact_details_id,contact_id,contact_type,contact_value");
$this->db->from("tbl_contact_details");
$this->db->where("tbl_contact_details.contact_id",$id);
$query = $this->db->get();
$data = $query->result();
echo $this->db->last_query();die;
return $data;
}
In above given code where should i put distinct to fetch only single occurance of contact_type record????
Please Help.......

Put it where you'd normally put in SQL, which is inside the select.

try put in a FALSE as a second parameter of select(), If it's still not working, please copy the error you see, including the query.

simplified version of yours:
Code:
function getdetaildatabyid($id)
{
$data=$this->db->select(“DISTINC contact_details_id,contact_id,contact_value”, FALSE)
->from(“tbl_contact_details”)
->where(“tbl_contact_details.contact_id”,$id)
->get()
->result();
echo $this->db->last_query();
return $data;

thnx for ur response but it shows following error:
<br />
<b>Fatal error</b>: Call to a member function result() on a non-object in <b>C:\wamp\www\final_product_ver01\application\models\model_contact.php</b> on line <b>130</b><br />
that means if i put distinct in my select statement....then it does not fetch any record

What version of CI you are using? I remember in the old version I cannot use result() directly if there is no data.
Try this one and let see what are returned:
Code:
function getdetaildatabyid($id)
{
$data=$this->db->select(“DISTINC contact_details_id,contact_id,contact_value”, FALSE)
->from(“tbl_contact_details”)
->where(“tbl_contact_details.contact_id”,$id)
->get();
var_dump($data);
// Maybe you could use these commented lines instead.
// if($data->num_rows()>0)
// return $data->result();
// else
// return array();
return $data->result();

not tested, but try this,
function getdetaildatabyid($id)
{
$this->db->select(“contact_details_id,contact_id,contact_value”);
$this->db->distinct('contact_type');
$this->db->from(“tbl_contact_details”);
$this->db->where(“tbl_contact_details.contact_id”,$id);
$query = $this->db->get();
$data = $query->result();
echo $this->db->last_query();die;
return $data;
}
or try this below,
function getdetaildatabyid($id)
{
$this->db->distinct('contact_type');
$this->db->from(“tbl_contact_details”);
$this->db->where(“tbl_contact_details.contact_id”,$id);
$query = $this->db->get();
$data = $query->result();
echo $this->db->last_query();die;
return $data;
}
