使用 Oracle Forms 11g 通过电子邮件发送外部文件

Question

我已配置电子邮件设置，并且能够通过 Oracle Forms 11g 发送电子邮件。现在我需要在发送的电子邮件中附加保存在我计算机中某处的 PDF。我经历了不同的程序，但无法成功发送 PDF 文件。

谢谢。

编辑：添加邮件发送程序代码

create or replace procedure send4 (p_sender IN VARCHAR2, p_recipient IN VARCHAR2, p_subject IN VARCHAR2, p_message IN VARCHAR2)
IS
crlf         VARCHAR2(2)  := chr(13)||chr(10);
l_mailhost VARCHAR2(255) := <IP ADDRESS>;
v_connection             UTL_SMTP.connection;

BEGIN
V_CONNECTION := utl_smtp.open_connection(l_mailhost, 25);
utl_smtp.Helo(V_CONNECTION, l_mailhost);
utl_smtp.Mail(V_CONNECTION, p_sender);
utl_smtp.Rcpt(V_CONNECTION, p_recipient);
utl_smtp.Data(V_CONNECTION,
'Date: '   || to_char(sysdate, 'Dy, DD Mon YYYY hh24:mi:ss') || crlf ||

Answer 1

如果您使用 Oracle Reports 11g 创建 PDF，您应该查看 DISTRIBUTION 设置。您可以显示 PDF 以及来自同一报告的电子邮件。否则，请考虑从您的 Oracle Form 启动一个批处理文件，该文件从命令行调用报告和电子邮件。

Answer 2

UTL_SMTP 无法承受大附件，这里有解决办法，您可以附加文件 创建java源

创建包体以使用上面编译的java

使用以下代码进行测试

var ErrorStatus NUMBER;

-- enable SQL*PLUS output;
SET SERVEROUTPUT ON
-- redirect java output into SQL*PLUS buffer;
exec dbms_java.set_output(5000);
BEGIN
   :ErrorStatus := SendMailJPkg.SendMail(
                SMTPServerName => 'localhost',

                Recipient => 'martin.zahn@akadia.com',
                CcRecipient => '',
                BccRecipient => '',
                Subject   => 'This is the subject line: Test JavaMail',
                Body => 'This is the body: Hello, this is a test' ||
                         SendMailJPkg.EOL || 'that spans 2 lines',
                ErrorMessage => :ErrorMessage,
                Attachments  => SendMailJPkg.ATTACHMENTS_LIST(
                                   'C:\Users\Zahn\Work\sendmail.sql',
