MAIL服務(wù)器為WIN2003,WINMAIL

1.保證ORACLE服務(wù)器到MAIL服務(wù)器網(wǎng)絡(luò)暢通,25端口打開

2.創(chuàng)建發(fā)送郵件的procedure如下:

---------------------------------------

CREATE OR REPLACE PROCEDURE SEND_MAIL

(as_sender in varchar2, --郵件發(fā)送者

as_recp in varchar2, --郵件接收者

as_subject in varchar2, --郵件標(biāo)題

as_msg_body in varchar2) --郵件內(nèi)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||'>'); --這里的'<' 一定要寫,不然會出現(xiàn)permanent error

utl_smtp.rcpt(lc_mail_conn, '<'||as_recp||'>');--這里的'<' 一定要寫,不然會出現(xiàn)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可以支持中文但body內(nèi)容不支持中文;

-- utl_smtp.write_data(lc_mail_conn, ls_msg_body); --這樣寫subject不支持中文

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(zhí)行發(fā)送郵件:

exec send_mail('heyu@163.net','admin@163.net','我我','this is a oracle test mail');

注意事項(xiàng):上面的過程如果在編譯中出現(xiàn)demo_base64.encode must be declared,請大家創(chuàng)建下面的包和包體;

---------------------------------

CREATE OR REPLACE PACKAGE demo_base64 IS

-- multiple lines with no more than 76 bytes each as required by

-- the MIME standard.

END;
