How to send E-mail from Oracle database

How to send E-mail from Oracle database


sqlplus / as sysdba
@?/rdbms/admin/utlmail.sql
@?/rdbms/admin/prvtmail.plb
Grant execute on UTL_MAIL to public;
ALTER SYSTEM SET smtp_out_server = 'mailhost' scope=both;
For Example:
BEGIN
UTL_MAIL.send(sender => 'shahid.ahmed@al-sadhan.com',
recipients => 'you@address.com',
subject => 'Test Mail',
message => 'Everythings is OK',
mime_type => 'text; charset=us-ascii');
END;
/
Note: You must have an outgoing SMTP server IP to configure sending mail from the database. 

Oracle allows you to send mail using procedure may be just message or message from tables.
CREATE TABLE EMP
(
ENO NUMBER(4),
ENAME VARCHAR2(50),
BASIC NUMBER(10,2));

CREATE OR REPLACE PROCEDURE SENDMAIL(TOO IN VARCHAR, FROMM IN VARCHAR, SUBJECT IN VARCHAR, BODY IN VARCHAR) AS
SMTP_HOST VARCHAR2(50) :='212.12.164.2';
PORT varchar2(2) :='25';
CONN UTL_SMTP.CONNECTION;

BEGIN
CONN:=UTL_SMTP.OPEN_CONNECTION('212.12.164.2', '25');
UTL_SMTP.HELO(CONN,'212.12.164.2');
UTL_SMTP.MAIL(CONN,'shahid.ahmedt@al-sadhan.com');
UTL_SMTP.RCPT(CONN,'xyz_abc@al-sadhan.com');
UTL_SMTP.DATA(CONN,'Test');
UTL_SMTP.QUIT(CONN);
END;
/

CREATE OR REPLACE TRIGGER EMP_TRIGGER AFTER INSERT ON EMP
FOR EACH ROW
BEGIN
sendmail('shahid.ahmedt@al-sadhan.com','xyz.abc@al-sadhan.com','Test',:new.ename);
END;

Desc emp;
insert into emp values (4, 'ahmed', 400);

The Above procedure will send a mail from oracle. When you call this procedure we need to pass To/From Address , Subject and Body of the message. For Example
To_address:shahid.ahmedt@al-sadhan.com
From_address: xyz.abc@al-sadhan.com
Subject and Body of the Message: Test

To Test this Procedure i created a temp table Emp with fields eno number(4), ename varchar2(50), basic number(10,2). Our aim is whenever some one insert record into emp table it needs to send an email with the Ename he entered. So we created Trigger after insert record into Emp table Call mail sending procedure with Employee name

Changing National Character Set AL16UTF16 to UTF8

Changing National Character Set AL16UTF16 to UTF8 The national character set is used for data that is stored in table columns of the types NCHAR, NVARCHAR2, and NCLOB.  In contrast, the database character set is used for data stored in table columns of the types CHAR, VARCHAR2 and CLOB. Like the database character set, the national character set is defined when the database is initially created and can usually no longer be changed, at least not easily or without involving quite a lot of work (export, recreate database, import). Except when creating the database, where the national character set is defined explicitly, it can change implicitly even when upgrading the database from Oracle8i to Oracle9i (or Oracle10g). You require SYSDBA authorization to change the national character set. Changing the national character set means changing an Oracle Dictionary entry, but no data is changed.  $sqlplus /nolog SQL> CONNECT / AS SYSDBA SQL> Select property_...
