MAIL伺服器為WIN2003,WINMAIL

1.保證ORACLE伺服器到MAIL伺服器網路暢通,25連接埠開啟

2.建立發送郵件的procedure如下:
---------------------------------------
CREATE OR REPLACE PROCEDURE SEND_MAIL
(as_sender in varchar2, --郵件寄件者
as_recp in varchar2, --郵件接收者
as_subject in varchar2, --郵件標題
as_msg_body in varchar2) --郵件內容
IS
ls_mailhost varchar2(30) := 'mail server'; -- address or IP
lc_mail_conn utl_smtp.connection;
ls_subject varchar2(100);
ls_msg_body varchar2(20000);
ls_username varchar2(256) := 'usercode';
ls_password varchar2(256) := 'password';
BEGIN
lc_mail_conn := utl_smtp.open_connection(ls_mailhost, 25);
utl_smtp.helo(lc_mail_conn, ls_mailhost);
utl_smtp.command(lc_mail_conn, 'AUTH LOGIN');
utl_smtp.command(lc_mail_conn, demo_base64.encode(utl_raw.cast_to_raw(ls_username)));
utl_smtp.command(lc_mail_conn, demo_base64.encode(utl_raw.cast_to_raw(ls_password)));
ls_subject := 'Subject: [' || upper(sys_context('userenv', 'db_name')) || '] - ' || as_subject;
ls_msg_body := as_msg_body;
utl_smtp.mail(lc_mail_conn, '<'||as_sender||'>'); --這裡的'<' 一定要寫,不然會出現permanent error
utl_smtp.rcpt(lc_mail_conn, '<'||as_recp||'>');--這裡的'<' 一定要寫,不然會出現permanent error
utl_smtp.open_data(lc_mail_conn);
ls_msg_body := 'From: ' || as_sender || chr(13) || chr(10) || 'To: ' || as_recp || chr(13) || chr(10) || ls_subject ||

chr(13) || chr(10) || chr(13) || chr(10) || ls_msg_body;
utl_smtp.write_raw_data(lc_mail_conn, utl_raw.cast_to_raw(ls_msg_body)); --這樣寫subject可以支援中文但body內容不支援中文;
-- utl_smtp.write_data(lc_mail_conn, ls_msg_body); --這樣寫subject不支援中文
utl_smtp.close_data(lc_mail_conn);
utl_smtp.quit(lc_mail_conn);
EXCEPTION
WHEN UTL_SMTP.INVALID_OPERATION THEN
dbms_output.put_line('invalid operation');
WHEN UTL_SMTP.TRANSIENT_ERROR THEN
dbms_output.put_line('transient error');
WHEN UTL_SMTP.PERMANENT_ERROR THEN
dbms_output.put_line('permanent error');
WHEN OTHERS THEN
dbms_output.put_line('others');
end send_mail;

3.執行發送郵件:
exec send_mail('heyu@163.net','admin@163.net','我我','this is a oracle test mail');

注意:以上過程如果在編譯中出現demo_base64.encode must be declared,請建立以下包和包體;
---------------------------------
CREATE OR REPLACE PACKAGE demo_base64 IS

-- Base64-encode a piece of binary data.
--
-- Note that this encode function does not split the encoded text into
-- multiple lines with no more than 76 bytes each as required by
-- the MIME standard.
--

END;
------------------------------------
