set column names my own in jqgrid - php

Question

I would like to add my own column names in jqgrid and also i want to prevent the column names that is automatically added by jqgrid according to sql query.
I am using this code to do that, but its also getting the name of columns which i have not declare in the method $grid->setColModel(null, null, $mylabels);
Can anyone please tell me what code i should to write for removing extra added column in jqgrid.
require_once '/var/www/html/zbajtmp/public/jqgrid/jq-config.php';
// include the jqGrid Class
require_once "/var/www/html/zbajtmp/public/jqgrid/php/jqGrid.php";
// include the driver class
require_once "/var/www/html/zbajtmp/public/jqgrid/php/jqGridPdo.php";
// Connection to the server
$conn = new PDO(DB_DSN,DB_USER,DB_PASSWORD);
// Tell the db that we use utf-8
$conn->query("SET NAMES utf8");
// Create the jqGrid instance
$grid = new jqGridRender($conn);
// Write the SQL Query
//$grid->SelectCommand = 'SELECT OrderID, OrderDate, CustomerID, Freight, ShipName FROM orders';
$grid->SelectCommand = 'SELECT * FROM clinic';
// set the ouput format to json
$grid->dataType = 'json';
// Let the grid create the model
//$grid->setColModel();
$mylabels = array(
"clinic_name"=>"Clinic ame",
"clinic_address"=>"Address",
"HomePhone"=>"Home Phone",
"WorkPhone"=>"Work Phone",
"Email_Id"=>"Email",
);
// Let the grid create the model with the desired labels
$grid->setColModel(null, null, $mylabels);
// Set the url from where we obtain the data
//$grid->setUrl('/var/www/html/zbajtmp/application/views/scripts/clinic/grid.php');
$grid->setUrl('http://sunlinux/zbajtmp/application/views/scripts/clinic/grid.php');
// Set grid caption using the option caption
$grid->setGridOptions(array(
"caption"=>"This is my custom Caption...",
"rowNum"=>50,
"sortname"=>"id",
"hoverrows"=>true,
"rowList"=>array(20,50,100,1000),
"width"=>"100%",
"height"=>350,
"footerrow"=>true,
"rownumbers"=>true,
"multiselect"=>true,
"altRows"=>true,
"altclass"=>'clsalt',
"loadtext"=>"<div class='loadingbox'>Please wait. Loading...</div>",
));
$grid->renderGrid('#grid','#pager',true, null, null, true,true);
$conn = null;
Thanks a lot.

You need to explicitly select the columns you want - SELECT * wont work
So you need to change :
$grid->SelectCommand = 'SELECT * FROM clinic';
to
$grid->SelectCommand = 'SELECT clinic_name,clinic_address,HomePhone,WorkPhone,Email_Id FROM clinic';
