I am using CodeIgniter. I have an employee table and records are

id |firstname | lastname | mobileno   | created_by

 2 |mnb       | nbgfv    | 1452145625 | 1

 3 |jhg       | uhgf     | 1452365478 | 2

 4 |poi       | ijuy     | 1458745632 | 2

 5 |tgf       | tgfd     | 1458745254 | 2

 6 |wer       | qwes     | 1523654512 | 2

Now My issue is in the column created_by. When I am displaying the record of any id value then I am getting the output like

    id |firstname | lastname | mobileno   | created_by

     3 |jhg       | uhgf     | 1452365478 | 2

But my expected output

id |firstname | lastname | mobileno   | created_by

 3 |jhg       | uhgf     | 1452365478 | mnb nbgfv

I have to display the name of created_by

I tried only this query.

   $get_single_emp_record = array('id' => 3);

   $this->db->where($get_single_emp_record);

   $query = $this->db->get('tbl_employee');

   $result = $query->row();

   if($result)

   {

   return $result;

   }

   else 

   {

   return 0;

   }

I have a hint (maybe this can give solution in your problem).
Try query like this :

SELECT 

t1.id , t1.firstname , t1.lastname ,t1.mobileno, 

CONCAT(t2.firstname ," ",t2.lastname ) AS createby 

FROM tbl_employee AS t1 

JOIN tbl_employee AS t2 ON t2.id = t1.created_by

WHERE t1.id = '3'

With above query you no need create temporary table or other additional tables.
I Tested it. >>>

Hopefully can help you. Thanks

you will have to create another table maybe tbl_creator which will have the id, creator_name then in your query you will perform a Join operation
