How To Define an Anonymous Block?

An anonymous block must have an execution part, which is a group of other PL/SQL statements enclosed in the BEGIN ... END statement. Here is a script on how to define a simple anonymous block with SQL*Plus:

SQL> set serveroutput on;

SQL> begin 
  2    dbms_output.put_line('Hello world!'); 
  3  end;
  4  /
Hello world!

PL/SQL procedure successfully completed.

"set serveroutput on;" allows dbms_output.put_line() to work.

"/" runs the anonymous block, which print the "Hello world!" message.
