如何在不使用Java的情况下压缩.csv文件并在电子邮件中附加Oracle plsql

Question

I am using Oracle 11.1 I have this plsql block which sends perfectly fine email with .csv attachment. 我使用的是Oracle 11.1，我有这个plsql块，可以发送带有.csv附件的完美电子邮件。

But I want to zip it and send. 但我想将其压缩并发送。 When I change the file extension as .zip, email comes fine as Report.zip ,but I cannot open the zip file, it says corrupted. 当我将文件扩展名更改为.zip时，将电子邮件作为Report.zip很好用，但是我无法打开该zip文件，它显示已损坏。 How do I compress? 如何压缩？

In the message section where you're transferring the .csv file you've got the MIME Content-Type set to "text/plain". 在要传输.csv文件的消息部分，您已将MIME Content-Type设置为“文本/纯文本”。 When you change the file name to Report.zip you need to change the Content-Type to "application/zip". 当您将文件名更改为Report.zip时，您需要将Content-Type更改为“ application / zip”。 Hopefully this will fix things up for you. 希望这会为您解决问题。
