Oracle Getting started with PL SQL

Hello World


SET serveroutput ON
DECLARE
 message CONSTANT VARCHAR2(32767):= 'Hello, World!';
BEGIN
 DBMS_OUTPUT.put_line(message);
END;
/

Command SET serveroutput ON is required in SQL*Plus and SQL Developer clients to enable the output of DBMS_OUTPUT. Without the command nothing is displayed.

The END; line signals the end of the anonymous PL/SQL block. To run the code from SQL command line, you may need to type / at the beginning of the first blank line after the last line of the code. When the above code is executed at SQL prompt, it produces the following result:

Hello, World!
PL/SQL procedure successfully completed.
