Sending Mails to Multiple Recipients using UTL_SMTP

Question

create or replace procedure send_mail(msg_text varchar2) is
c utl_smtp.connection;
PROCEDURE send_header(name IN VARCHAR2, header IN VARCHAR2) AS
BEGIN
utl_smtp.write_data(c, name || ': ' || header || utl_tcp.CRLF);
END;
BEGIN
c := utl_smtp.open_connection('outlook.abc.com');
utl_smtp.helo(c, 'abc.com');
utl_smtp.mail(c, '[email protected]');
utl_smtp.rcpt(c, '[email protected]');
utl_smtp.open_data(c);
send_header('From', '"root" <[email protected]>');
send_header('To', '"abc" <[email protected]>');
send_header('Subject', 'WARNING: Salary has been changed');
utl_smtp.write_data(c, utl_tcp.CRLF || msg_text);
utl_smtp.close_data(c);
utl_smtp.quit(c);
EXCEPTION
WHEN utl_smtp.transient_error OR utl_smtp.permanent_error THEN
BEGIN
utl_smtp.quit(c);
EXCEPTION
WHEN utl_smtp.transient_error OR utl_smtp.permanent_error THEN
NULL; -- When the SMTP server is down or unavailable, we don't have
-- a connection to the server. The quit call will raise an
-- exception that we can ignore.
END;
raise_application_error(-20000,
'Failed to send mail due to the following error: ' || sqlerrm);
END;
==============
when I execute the above using
sql> exec send_mail('hihihih');
I am getting the mails..no problems...
So..I created the following trigger and used the above procedure to send the mail...
CREATE OR REPLACE TRIGGER test_emp_table_trg
AFTER UPDATE
ON test_emp_table
FOR EACH ROW
WHEN (NEW.sal <> OLD.sal)
DECLARE
l_employee_name VARCHAR2 (240);
l_old_sal VARCHAR2 (240);
l_new_sal VARCHAR2 (240);
l_message VARCHAR2 (240);
BEGIN
/* Gets the employee full name */
BEGIN
SELECT ename
INTO l_employee_name
FROM test_emp_table
WHERE empno = :OLD.empno;
EXCEPTION
WHEN OTHERS
THEN
l_employee_name := NULL;
END;
/* Gets the old Salary */
BEGIN
SELECT sal
INTO l_old_sal
FROM test_emp_table
WHERE empno = :OLD.empno;
EXCEPTION
WHEN OTHERS
THEN
l_old_sal := 0;
END;
/* Gets the new salary */
BEGIN
SELECT sal
INTO l_new_sal
FROM test_emp_table
WHERE empno= :NEW.empno;
EXCEPTION
WHEN OTHERS
THEN
l_new_sal := 0;
END;
l_message:=
'Employee Name= '
|| l_employee_name
|| 'Old Salary= '
|| l_old_sal
|| 'New Salary= '
|| l_new_sal;
BEGIN
send_mail (l_message);
END;
END;
===================
I am not getting desired output..what might be problem friends...I am getting 0 values for old salary and new salary......
One more thing..when i use 2 receipts in the send_mail procedure like this...I added the following lines in the procedure to send to multiple receipents..
======
utl_smtp.rcpt(c, '[email protected]');
utl_smtp.rcpt(c, '[email protected]');
=============
Pleas have a look and correct me, where i went wrong....

Hi, You can use the following routine to send mail to multiple recipients through utl_smtp.
create or replace package mail_pkg
as
type array is table of varchar2(255);
procedure send( p_sender_e_mail in varchar2,
p_from in varchar2,
p_to in array default array(),
p_cc in array default array(),
p_bcc in array default array(),
p_subject in varchar2,
p_body in long );
end;
create or replace package body mail_pkg
begin
g_crlf char(2) default chr(13)||chr(10);
g_mail_conn utl_smtp.connection;
g_mailhost varchar2(255) := 'ur mail server';
function address_email( p_string in varchar2,
p_recipients in array ) return varchar2
is
l_recipients long;
begin
for i in 1 .. p_recipients.count
loop
utl_smtp.rcpt(g_mail_conn, p_recipients(i));
if ( l_recipients is null )
then
l_recipients := p_string || p_recipients(i) ;
else
l_recipients := l_recipients || ', ' || p_recipients(i);
end if;
end loop;
return l_recipients;
end;
procedure send( p_sender_e_mail in varchar2,
p_from in varchar2,
p_to in array default array(),
p_cc in array default array(),
p_bcc in array default array(),
p_subject in varchar2,
p_body in long );
end;
is
l_to_list long;
l_cc_list long;
l_bcc_list long;
l_date varchar2(255) default
to_char( SYSDATE, 'dd Mon yy hh24:mi:ss' );
procedure writeData( p_text in varchar2 )
as
begin
if ( p_text is not null )
then
utl_smtp.write_data( g_mail_conn, p_text || g_crlf );
end if;
end;
begin
g_mail_conn := utl_smtp.open_connection(g_mailhost, 25);
utl_smtp.helo(g_mail_conn, g_mailhost);
utl_smtp.mail(g_mail_conn, p_sender_e_mail);
l_to_list := address_email( 'To: ', p_to );
l_cc_list := address_email( 'Cc: ', p_cc );
l_bcc_list := address_email( 'Bcc: ', p_bcc );
utl_smtp.open_data(g_mail_conn );
writeData( 'Date: ' || l_date );
writeData( 'From: ' || nvl( p_from, p_sender_e_mail ) );
writeData( 'Subject: ' || nvl( p_subject, '(no subject)' ) );
writeData( l_to_list );
writeData( l_cc_list );
utl_smtp.write_data( g_mail_conn, '' || g_crlf );
utl_smtp.write_data(g_mail_conn, p_body );
utl_smtp.close_data(g_mail_conn );
utl_smtp.quit(g_mail_conn);
end;
end;
begin
mail_pkg.send
(p_sender_e_mail => 'urmail',
p_from => 'urmail',
p_to => mail_pkg.array( 'urmail','othersmail' ),
p_cc => mail_pkg.array( ' othermail ' ),
p_bcc => mail_pkg.array( '' ),
p_subject => 'This is a subject',
p_body => 'Hello Buddy, this is the mail you need' );
end;
