实例讲解如何通过Oracle成功发送邮件

来源：赛迪网    作者：yashi

LINUX AS3+Oracle 9.2||10.20.1从Oracle成功发送邮件:

示例如下：

具体的测试环境:LINUX AS3 , Oracle 9.0.2.4

SQL> select * from v$version;

BANNER

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

Oracle9i Enterprise Edition Release 9.2.0.4.0 - Production

PL/SQL Release 9.2.0.4.0 - Production

CORE 9.2.0.3.0 Production

TNS for Linux: Version 9.2.0.4.0 - Production

NLSRTL Version 9.2.0.4.0 - Production

SQL> select * from v$version;

Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Prod

PL/SQL Release 10.2.0.1.0 - Production

CORE 10.2.0.1.0 Production

TNS for Linux: Version 10.2.0.1.0 - Production

NLSRTL Version 10.2.0.1.0 - Production

MAIL服务器为WIN2003,WINMAIL

1.保证ORACLE服务器到MAIL服务器网络畅通,25端口打开

2.创建发送邮件的procedure如下:

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

CREATE OR REPLACE PROCEDURE SEND_MAIL

(as_sender in varchar2, --邮件发送者

as_recp in varchar2, --邮件接收者

as_subject in varchar2, --邮件标题

as_msg_body in varchar2) --邮件内容

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||'>'); --这里的'<' 一定要写,不然会出现permanent error

utl_smtp.rcpt(lc_mail_conn, '<'||as_recp||'>');--这里的'<' 一定要写,不然会出现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)); --这样写subject可以支持中文但body内容不支持中文;

-- utl_smtp.write_data(lc_mail_conn, ls_msg_body); --这样写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.执行发送邮件:

exec send_mail('[e-mail]','[e-mail]','我我','this is a oracle test mail');

注意事项:上面的过程如果在编译中出现demo_base64.encode must be declared,请大家创建下面的包和包体;

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

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.

--

FUNCTION encode(r IN RAW) RETURN VARCHAR2;

END;

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

map vc2_table;
