SAS 企业指南 - 如何从网站下载 ZIP 文件，提取其内容并运行它？

Question

I would like to have a task to download a continuously updated.ZIP data file from a specific website, extract its contents and run the file inside.

I am looking for a program code that performs these tasks and, so to speak, if the data on the website is updated, then my data file is also updated with it.

How can I do it?

Please help. SAS Enterprise Guide 8.2

I didn't find a solution for it.

Answer 1

Read Chris method here for reading a zip file using filename statement: https://blogs.sas.com/content/sasdummy/2014/01/29/using-filename-zip/

Chris is the community director at SAS (something like that). A zip file will be locked on an update. Check the file date and store the date somewhere so you can see if it changed.

There are lots of ways to approach your problem and I dont know your constraints. Start with Chris' post and work from there.
