Oracle Database Interview Question:

How To Define an Anonymous Block?

Submitted by: Administrator

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.
