E-Mails mit Email Delivery-Service in Autonomous Database senden
Beschreibt die Schritte zum Senden von E-Mails mit UTL_SMTP in Autonomous Database on Dedicated Exadata Infrastructure.
So senden Sie E-Mails mit
UTL_SMTP:
Weitere Informationen finden Sie unter UTL_SMTP in Oracle Database 19c PL/SQL-Packages und Typenreferenz oder Oracle Database 23ai PL/SQL-Packages und Typenreferenz.
Weitere Informationen zur Verwendung von UTL_SMTP mit Autonomous Database finden Sie unter Hinweise zur Verwendung von Datenbank-PL/SQL-Packages.
Beispielcode für das Senden von E-Mail mit SMTP
Zeigt Beispielcode für das Senden von E-Mails mit UTL_SMTP in einer Autonomous Database.
Beispielcode
-- As ADMIN user, set up ACE to access SMTP host
connect admin/[password]@[ADBD-host]/[pdbname]_tp.atp.oraclecloud.com
begin

host => '[SMTP_Server_address]',

upper_port => 25,
ace => xs$ace_type(
privilege_list => xs$name_list('smtp'),
principal_name => '[database_user]',
principal_type => xs_acl.ptype_db));
end;

-- If using secure SMTP, set up ACE to wallet for certificate-based secure (TLS) email
