Code to send email using PLSQL

You can use UTL_SMTP and UTL_TCP to send email attachment from Oracle Version 8i onwards.
Sample Code:

 DECLARE  
 v_From VARCHAR2(80) := 'oracle@mycompany.com';  
 v_Recipient VARCHAR2(80) := 'test@mycompany.com';  
 v_Subject VARCHAR2(80) := 'test subject';  
 v_Mail_Host VARCHAR2(30) := 'mail.mycompany.com';  
 v_Mail_Conn utl_smtp.Connection;  
 crlf VARCHAR2(2) := chr(13)||chr(10);  
 BEGIN  
 v_Mail_Conn := utl_smtp.Open_Connection(v_Mail_Host, 25);  
 utl_smtp.Helo(v_Mail_Conn, v_Mail_Host);  
 utl_smtp.Mail(v_Mail_Conn, v_From);  
 utl_smtp.Rcpt(v_Mail_Conn, v_Recipient);  
 utl_smtp.Data(v_Mail_Conn,  
 'Date: ' || to_char(sysdate, 'Dy, DD Mon YYYY hh24:mi:ss') || crlf ||  
 'From: ' || v_From || crlf ||  
 'Subject: '|| v_Subject || crlf ||  
 'To: ' || v_Recipient || crlf ||  
 'MIME-Version: 1.0'|| crlf || -- Use MIME mail standard  
 'Content-Type: multipart/mixed;'|| crlf ||  
 ' boundary="-----SECBOUND"'|| crlf ||  
 crlf ||  
 '-------SECBOUND'|| crlf ||  
 'Content-Type: text/plain;'|| crlf ||  
 'Content-Transfer_Encoding: 7bit'|| crlf ||  
 crlf ||  
 'some message text'|| crlf || -- Message body  
 'more message text'|| crlf ||  
 crlf ||  
 '-------SECBOUND'|| crlf ||  
 'Content-Type: text/plain;'|| crlf ||  
 ' name="excel.csv"'|| crlf ||  
 'Content-Transfer_Encoding: 8bit'|| crlf ||  
 'Content-Disposition: attachment;'|| crlf ||  
 ' filename="excel.csv"'|| crlf ||  
 crlf ||  
 'CSV,file,attachement'|| crlf || -- Content of attachment  
 crlf ||  
 '-------SECBOUND--' -- End MIME mail  
 );  
 utl_smtp.Quit(v_mail_conn);  
 EXCEPTION  
 WHEN utl_smtp.Transient_Error OR utl_smtp.Permanent_Error then
