Fornisce alcuni extra:
- Puoi opzionalmente allegare un file (txt o binario, ma è supportato solo un file)
FromeSubjectpuò contenere caratteri non ASCII come öäü (ovviamente anche il corpo della posta può)- Più destinatari
- Utilizza automaticamente il set di caratteri corretto dal database
- Rileva automaticamente il corpo della posta in testo normale o HTML
- Piè di pagina comune per indicare la posta
Nota, non perdere le righe vuote UTL_SMTP.WRITE_DATA(con, UTL_TCP.CRLF); , sono necessari per la posta corretta.
Quindi puoi utilizzare la procedura ad esempio in questo modo:
DECLARE
Message CLOB;
BEGIN
FOR aMsg IN (SELECT Log_id, Procedure_name, Fail_type, Message FROM log_messages ORDER BY Log_id) LOOP
Message := Message || aMsg.Log_id ||' - '|| aMsg.Procedure_name ||' - '|| aMsg.Fail_type ||' - '|| aMsg.Message || CHR(13);
end loop;
SendMail(
Subject => 'You got some logs',
Message => Message,
ToMail => VARCHAR_TABLE_TYPE('[email protected]'),
FromMail => '[email protected]',
FromName => 'Oracle User: '||USER);
END;
oppure puoi inserire i log come allegati in questo modo:
DECLARE
Message CLOB;
Attachment CLOB;
BEGIN
Message := 'Open attachment to see log file';
FOR aMsg IN (SELECT Log_id, Procedure_name, Fail_type, Message FROM log_messages ORDER BY Log_id) LOOP
Attachment := Attachment || aMsg.Log_id ||' - '|| aMsg.Procedure_name ||' - '|| aMsg.Fail_type ||' - '|| aMsg.Message || CHR(13);
end loop;
Mailing.SendMail(
Subject => 'You got some logs',
Message => Message,
ToMail => VARCHAR_TABLE_TYPE('[email protected]'),
FromMail => '[email protected]',
FromName => 'Oracle User: '||USER,
TxtAttachment => Attachment,
FileName => 'logfile.txt');
END;
