How to send SMS from ORACLE forms 10g

Here's how to send sms message from Oracle application.



Explain:



Say we are subscribed to msegat.com service with the following credentials:



User Name : OMAR

Password :  123

User Sender : ThreeM    ( you got it from your sms site)

Text we'll send : My_Test_Message

Phone we'll send message to : 966123456789



Here's how the code will run:

/*Start of SMS code*/

SET serveroutput ON
SET Define OFF
 
DECLARE
    HTTP_REQ      UTL_HTTP.REQ;
    HTTP_RESP     UTL_HTTP.RESP;
    URL_TEXT      VARCHAR2(32767);
    URL VARCHAR2(2000);
     
     SMS_MSG VARCHAR2(160) := 'Congratulations! Your database has been configured propoerly for sending SMS through a 3rd party SMS Gateway';
     
BEGIN
    DBMS_OUTPUT.ENABLE(1000000);
--Based on your service provider, the following link format may differ from
--What we have specified below!   
 
UTL_URL.Escape(SMS_MSG,TRUE);
--UTL_URL.Escape manages escape characters like SPACE between words in a message.
     
   
 
    HTTP_REQ  := UTL_HTTP.BEGIN_REQUEST(URL);
    
    UTL_HTTP.SET_HEADER(HTTP_REQ, 'User-Agent', 'Mozilla/4.0');
    HTTP_RESP := UTL_HTTP.GET_RESPONSE(HTTP_REQ);
 
    -- Process Request
    LOOP
        BEGIN
            URL_TEXT := null;
            UTL_HTTP.READ_LINE(HTTP_RESP, URL_TEXT, TRUE);
            DBMS_OUTPUT.PUT_LINE(URL_TEXT);
 
            EXCEPTION
                WHEN OTHERS THEN EXIT;
        END;
    END LOOP;
 
    UTL_HTTP.END_RESPONSE(HTTP_RESP);
END;
/*End of SMS code*/


If you got an error , you can remove :

SET serveroutput ON
SET Define OFF
