通过Oracle发送Email
?本篇是通过Oracle10g发送Email实例，该Procedure支持中文邮件、HTML代码、多收件人。
?? 在Procedure中p_receiver为收件人地址，多收件人以“，”（英文逗号）分割，p_sub为邮件标题，p_txt为邮件内容（支持HTML）。代码如下：
create or replace procedure bsd_sendemail (p_receiver varchar2,p_sub varchar2,p_txt varchar2)
is
p_user varchar2(30) := '';
p_pass varchar2(30) := '';
p_sendor varchar2(20) := 'Gnie';
p_server varchar2(20) := 'Mail_Server_IP';
p_port number := 25;
p_need_smtp number := 0;
p_subject varchar2(4000);
l_crlf varchar2(2) := utl_tcp.crlf;
l_sendoraddress varchar2(4000);
l_splite??????? varchar2(10) := '++';
boundary??????????? constant varchar2(256) := '-----BYSUK';
first_boundary????? constant varchar2(256) := '--' || boundary || l_crlf;
last_boundary?????? constant varchar2(256) := '--' || boundary || '--' || l_crlf;
multipart_mime_type constant varchar2(256) := 'multipart/mixed; boundary="' || boundary || '"';
type address_list is table of varchar2(100) index by binary_integer;
my_address_list address_list;
---------------------------------------分割邮件地址----------------------------------------------
procedure p_splite_str(p_str varchar2,p_splite_flag int default 1) is
?? l_addr varchar2(254) := '';
?? l_len? int;
?? l_str? varchar2(4000);
?? j????? int := 0; --表示邮件地址或者附件的个数
begin
?? /*处理接收邮件地址列表，包括去空格、将;转换为,等*/
?? l_str := trim(rtrim(replace(replace(p_str, ';', ','), ' ', ''), ','));
?? l_len := length(l_str);
?? for i in 1 .. l_len loop
???? if substr(l_str, i, 1) <> ',' then
?????? l_addr := l_addr || substr(l_str, i, 1);
???? else
?????? j := j + 1;
?????? if p_splite_flag = 1 then --表示处理邮件地址
???????? --前后需要加上'<>'，否则很多邮箱将不能发送邮件
???????? l_addr := '<' || l_addr || '>';
???????? --调用邮件发送过程
???????? my_address_list(j) := l_addr;
?????? end if;
?????? l_addr := '';
???? end if;
???? if i = l_len then

------------------------------------------------写邮件头和邮件内容------------------------------------------
procedure write_data(p_conn?? in out nocopy utl_smtp.connection,

end;
----------------------------------------写mime邮件尾部-----------------------------------------------------
procedure end_boundary(conn in out nocopy utl_smtp.connection, last in boolean default false) is
