I create my custom module but the data from database cannot show.

The module's name is mod_ballreport
The table 's name in database is mod_ballreport

The source code of the mod_ballreport.php is

<?php
if(!defined('sugarEntry') || !sugarEntry) die('Not A Valid Entry Point');
require_once('data/SugarBean.php');
require_once('include/utils.php');

class mod_ballreport extends SugarBean {
var $id;
var $description;
var $report_sql;
var $name;
var $assigned_user_id;
var $date_modified;
var $deleted;

var $table_name = "mod_ballreport";
var $module_dir = "mod_ballreport";

var $track_on_save=true;
var $object_name = "mod_ballreport";

function mod_ballreport()
{
parent::SugarBean();
}
}
?>

The code of vardefs.php is
<?php
#Ensure that the file can only be accessed via SugarCRM
if(!defined('sugarEntry') || !sugarEntry) die('Not A Valid Entry Point');

#Define the dictionary
$dictionary['mod_ballreport'] = array(
#Define the table to be used, their data types, labels, etc
'table' => 'ppi_reports',
'unified_search' => true,
'comment' => 'Reports',
#Define the fields to be used
'fields' => array(
'id' => array(
'name' => 'id',
'vname' => 'LBL_ID',
'required' => true,

'type' => 'datetime',
'required' => false,

'vname' => 'LBL_DELETED',
'type' => 'bool',
'required' => true,
'reportable'=>false,
'comment' => 'Record deletion indicator',
),
),
);
?>


The code of listviewdef.php is
<?php
if(!defined('sugarEntry') || !sugarEntry) die('Not A Valid Entry Point');

$listViewDefs['mod_ballreport'] = array(
'NAME' => array(
'width' => '50',
'label' => 'LBL_NAME',
'default' => true
),
'DESCRIPTION' => array(
'width' => '50',
'label' => 'LBL_DESCRIPTION',
'default' => true
),
'REPORT_SQL' => array(
'width' => '50',
'label' => 'LBL_REPORT_SQL',
'default' => true),
);
?>

The code of listview.php is
<?php
if(!defined('sugarEntry') || !sugarEntry) die('Not A Valid Entry Point');


require_once ('modules/mod_ballreport/mod_ballreport.php');
require_once('include/ListView/ListViewSmarty.php');
require_once('modules/mod_ballreport/metadata/listviewdefs.php');


$seedmod_ballreport = new mod_ballreport();
$lv = new ListViewSmarty();
$lv->displayColumns = $listViewDefs['mod_ballreport'];
$lv->setup($seedmod_ballreport,'include/ListView/ListViewGeneric.tpl', $where,$listViewDefs['mod_ballreport']);
echo $lv->display();



?>

The output is

have you defined your fields in your custom module's field_array.php file?
