用户根本不需要单击任何地方或执行任何操作；当这些警报以动态方式到达时，就会立即显示出来（一种“推送”模式）。
The user does not need to click anywhere or to perform any action at all; these alerts just appear when they arrive dynamically (a push-model).
由于您只对查看数据感兴趣，因此希望以匿名方式执行，在调用之后立即发出一条回滚语句来隐藏您的踪迹，如清单7所示。
Because you are only interested in viewing the data, you would prefer to do so anonymously, issue a rollback statement immediately after the call to cover your tracks, as shown in Listing 7.
