本来是想把解决PLSQL中文乱码问题,可问题是一个接着一个的出现,想看看中文乱码问题解决没有,结果查询表时又弹出这样一个错误。
拿着有道查了一下,说是动态性能表没有权利被访问。上网查了一下相关的问题,才知道原来PLSQL在用户运行过程中,要收集用户统计信息,但是由于我们现在登录的用户没有权限访问v$session,v$sesstat和v$statname视图,所以不能收集当前用户的统计信息,和PLSQL工具中配置的Automatic Statistics相冲突,所以会出现上面的提示信息。
所以我的解决方案是彻底禁掉PLSQL的统计功能。选择Tools——Preferences,然后找到Options,把Automatic Statistics选项前面的小勾去掉,点击保存,退出。
这个是最简单的办法,除此之外,又查到两个方法,其中一个比较狗血,就是把上面问题提示框中的“Don't show this message again”选项勾选,让下次不要再出现这个提示框,这个方法有点让人不能接受啊。
另外一个方法就是给访问用户授权,让用户有权限访问这三个视图。第三种方法给大家推荐一个博客,我觉得这个博客中介绍的非常详细,在这里我就不再赘述了。博客地址:http://blog.itpub.net/519536/viewspace-614671/
无论哪种方法解决了问题,最终的目的都是为了方便大家学习。PLSQL让我很头疼,但是也让我接触了很多它的意外状况,让我能够对它认识更深刻,了解的更深入。

Java 8 introduces the Stream API, providing a powerful and expressive way to process data collections. However, a common question when using Stream is: How to break or return from a forEach operation? Traditional loops allow for early interruption or return, but Stream's forEach method does not directly support this method. This article will explain the reasons and explore alternative methods for implementing premature termination in Stream processing systems. Further reading: Java Stream API improvements Understand Stream forEach The forEach method is a terminal operation that performs one operation on each element in the Stream. Its design intention is
