大家好,
我有一个SSIS包(Sql Server 2008),它执行一些数据流和文件操作,最后将文件上传到FTP服务器。
我已经完成了大部分工作,但还有一个关键的问题。使用“数据流”,可以生成一个文本文件,其中包含来自数据库的数据。现在该文件被压缩并附带时间戳,例如:“filename_08132012.zip”。
时间戳每天都会更改,因此每次上传到FTP服务器时都是一个新文件。因此,我使用了“脚本任务”而不是“FTP任务”(我无法想出一种方法使其工作),它查找具有当天日期的文件并将其上传到FTP服务器。以下是代码,但我有两个相关问题:
- 我希望这个“脚本任务”能够选择当天的文件,例如:filename_08132012.zip,filename_08142012.zip。我有将日期转换为字符串格式的正确代码。但由于某种原因,它没有起作用。
- 如何通过脚本文件的执行步骤,类似于Visual Studio允许VB.net代码的方式?该脚本任务GUI不允许进行调试。
- 它上传一个空文件到FTP服务器。一个大小为0字节的文件。我该如何进行故障排除?
