如何使用ADOdb PHP库执行MSSQL存储过程

我已经按照ADOdb文档中的说明进行了操作，我正试图在sql server 2008数据库上执行一个存储过程，如下所示：

$stmt = $db->PrepareSP('usp_insert_aweber_list');
$db->InParameter($stmt,$id,'List_ID',false,SQLINT4);
$db->InParameter($stmt,$name,'Name',255,SQLVARCHAR);
$db->InParameter($stmt,$campaigns_collection_link,'Campaign_Collections_Link',255,SQLVARCHAR);
$db->InParameter($stmt,$custom_fields_collection_link,'Custom_Fields_Collection_Link',255,SQLVARCHAR);
$db->InParameter($stmt,$http_etag,'HTTP_Etag',255,SQLVARCHAR);
$db->InParameter($stmt,$resource_type_link,'Resource_Type_Link',255,SQLVARCHAR);
$db->InParameter($stmt,$self_link,'Self_Link',255,SQLVARCHAR);
$db->InParameter($stmt,$subscribers_collection_link,'Subscribers_Collection_Link',255,SQLVARCHAR);
$db->InParameter($stmt,$total_subscribers,'Total_Subscribers',false,SQLINT4);
$db->InParameter($stmt,$total_subscribed_subscribers,'Total_Subscribed_Subscribers',false,SQLINT4);
$db->InParameter($stmt,$total_subscribers_subscribed_today,'Total_Subscribers_Subscribed_Today',false,SQLINT4);
$db->InParameter($stmt,$total_subscribers_subscribed_yesterday,'Total_Subscribers_Subscribed_Yesterday',false,SQLINT4);
$db->InParameter($stmt,$total_unconfirmed_subscribers,'Total_Unconfirmed_Subscribers',false,SQLINT4);
$db->InParameter($stmt,$total_unsubscribed_subscribers,'Total_Unsubscribed_Subscribers',false,SQLINT4);
$db->InParameter($stmt,$web_form_split_tests_collection_link,'Web_Form_Split_Tests_Collection_Link',255,SQLVARCHAR);
$db->InParameter($stmt,$web_forms_collection_link,'Web_Forms_Collection_Link',255,SQLVARCHAR);
$rs = $db->Execute($stmt);
if (!$rs){
    print $db->ErrorMsg();
    echo '<br /><br />';
}

上面的代码位只输出以下错误消息：

[Microsoft][ODBC SQL Server Driver][SQL Server]Procedure or function 'usp_insert_aweber_list' expects parameter '@List_ID', which was not supplied.

我相信我已经在第一个$db->InParameter（）调用中提供了List_ID参数。如果我错了，请纠正我。在任何人回复"在参数名称前添加@"之前，文档指出不需要它，我已经尝试过了，但它会导致相同的错误消息。
