Magento delete order Script

Php script for delete particular status order from admin in magento


require_once('app/Mage.php');
Mage::app('admin');
Mage::getSingleton("core/session", array("name" => "adminhtml"));
Mage::register('isSecureArea',true);
$collection = Mage::getResourceModel('sales/order_collection')
->addAttributeToSelect('*')
->setPageSize(5000)
->addFieldToFilter('status', 'closed')->load();

foreach ($collection as $col) {
Mage::log($col->getIncrementId() . ' order deleted ');
try {
$col->delete();
} catch (Exception $e) {
throw $e;
}
}

change the status for whatever order you want to delete.. eg. if you want to delete 'closed' order than in addFieldToFilter status write 'closed' for complete 'completed' so on..
