I'm just getting into PL/SQL, and I tried to run the following code, and I am getting anonymous block completed, but I think I should be getting Testing output. Does any know what I am doing wrong?
DECLARE
message varchar2(20) := 'Testing output';
BEGIN
dbms_output.put_line(message);
END;

In the DBMS Output window, choose the "plus" icon and select the connection that you want to write data to the DBMS Output window. Then run the PL/SQL block in the SQL Worksheet window using the right arrow (Ctrl+Enter in Windows). You'll see the output appear in the DBMS Output window.
The PL/SQL anonymous block statement is an executable statement that can contain PL/SQL control statements and SQL statements. It can be used to implement procedural logic in a scripting language. In PL/SQL contexts, this statement can be compiled and executed by the data server.
"anonymous block completed" means, that the execution of the block has finished without errors. Each call to Oracle, returns a return or exit code.
Execute a PL/SQL anonymous block using SQL*Plus Second, turn on the server output using the SET SERVEROUTPUT ON command so that the DBMS_OUTPUT. PUT_LINE procedure will display text on the screen. Third, type the code of the block and enter a forward slash ( / ) to instruct SQL*Plus to execute the block.
Viewing the DBMS_OUTPUT depends on the program.
SQL*Plus and Oracle SQL Developer
Run SET SERVEROUTPUT ON; first. This is all that's necessary in SQL*Plus or recent versions of Oracle SQL Developer.
SET SERVEROUTPUT ON;
begin
dbms_output.put_line('Testing output');
end;
/
PL/SQL Developer
Output is automatically detected and displayed in the "Output" tab.

Yes, in Oracle SQL Developer put the statement:
SET SERVEROUTPUT ON;
just before your DECLARE keyword and this should work.
I couldn't find View -> DBMS Output and I'm using version 1.5.5.
