推荐答案
set serveroutput on;
和clear;
是sqlplus命令,而不是plsql,因此它们可能无法在其他环境中使用.
我不知道您是否可以通过这种方式将消息写入某些标准输出,但是如果您想从vs2010中调试plsql,则可以使用本教程:

The set serveroutput on;
and clear;
are sqlplus commands, not plsql so they will probably won't work in other environments.
I don't know if you can write messages to some standard output this way, but if you want to debug your plsql from vs2010, you can use this tutorial:

或使用 UTL_FILE 记录到文件
