an orcale exception has occurred in you code,if the code contains an exception handler you can continuing stepping through the handler;otherwise,the error message will display and the next step will exit execution.
------解决方法--------------------------------------------------------
出错了嘛。
如果你有写Exception处理机制,那么可以继续执行,否则就退出运行啊
BEGIN
........
EXCEPTION
WHEN OTHERS THEN
V_RETURN := SQLERRM;
END;
