我刚刚开始使用 PL/SQL，我尝试运行以下代码，并且我正在完成匿名块，但我认为我应该获得测试输出.有谁知道我做错了什么?
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;

查看 DBMS_OUTPUT 取决于程序.
Viewing the DBMS_OUTPUT depends on the program.
SQL*Plus 和 Oracle SQL Developer
首先运行 SET SERVEROUTPUT ON;.这就是 SQL*Plus 或最新版本的 Oracle SQL Developer 所需的全部内容.
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 开发人员
自动检测输出并显示在输出"选项卡中.
Output is automatically detected and displayed in the "Output" tab.
