我有这个在 SQL Server 代理中运行的查询，我需要能够选择正确的文件。目前我让它拾取 D 驱动器上的随机文件，但我需要它拾取刚刚创建的文件。代码如下，如下所示：

'D:\Argosy_import_'+CONVERT(char(8),GETDATE(),1)+'_0001.txt','/',''

我怎样才能让它在这里工作：

@file_attachments = 'D:Argosy_import_051713_0001.txt';

此外，我尝试在主题中使用日期参数，但这也不起作用。我怎样才能让它工作/；

     @subject = 'Import file for @PeriodStart',

对此的任何指导或帮助都会很棒。

Declare @PeriodStart Datetime
Declare @PeriodEnd Datetime

SELECT @PeriodEnd = GetDate()
,@PeriodStart = dateadd(hour,-168,getdate())
