有人能帮我UTL_SMTP。WRITE_DATA发送电子邮件附件。我不能发送多行代码内的附件。
当我写UTL_SMTP.WRITE_DATA来写入附件内的数据时,它不起作用。
下面是附加代码,当i=1时,它仅从第二个游标发送1行的附件。
快来人帮忙。

与其调试你的代码,我不如和你分享我自己的sendmail函数,你可以用它来找出你做错了什么。一个让我立刻意识到的区别是我使用base64编码而不是8位编码,以防止附件中的任何内容扰乱SMTP。我确信有多种方法可以做到这一点,但这一方法已经为我工作了很多年:

这是HTML在身体启用。我有另一个是纯文本。我喜欢有HTML,所以我可以做一些简单的格式,如粗体和斜体等。
但是我的附件往往是文本,即使CSV或XML是为Excel准备的。所以,我总是使用mime 'text/plain'作为附件。将附件编译为CLOB并将其传递到附件参数之一。
