Try It works for me.

$items['package/%/edit'] = array(
'title' => 'Edit data Row',
'page callback' => 'pricepackages_form_update',
'page arguments' =>array(1),
'type' => MENU_NORMAL_ITEM,
'access callback' => TRUE,
);


function pricepackages_form_update($arg){
$my_object = db_select('your table name', 'a')
->fields('a')
->condition('your node id parameter', $arg )
->execute()
->fetchAssoc();
return drupal_get_form('your form menu', $my_object);
}
