All,
I have an SSIS package (Sql Server 2008), that does a few data flow and file operations and then finally uploads the file to an FTP Server.
I was able to get most of the work done, but one last critical piece. Using 'Data Flow' a text file is generated with data from the database. Now that file is zipped with a timestamp at the end Ex: "filename_08132012.zip".
The timestamp changes every day, so its a new file every time to upload to the FTP server. So, instead of "FTP Task" (I could not figure out a way to make this work), I have a "Script Task" that looks for a file with today's date and uploads it to the FTP server. Following is the code, but I have two questions related to this:
- I want this "Script Task" to pick up that day's file ex: filename_08132012.zip, filename_08142012.zip. I have the code to convert date to string with proper format. But for some reason, it is not.
- How to step through the execution of this script file, the was Visual Studio allows for VB.net code? This script task GUI is not allowing to step through.
- It uploads an empty file to the FTP server. A file with 0 bytes. How do I troubleshoot this?
