This means that after the context switch , any resource within the server that the impersonated login has permissions on can be accessed 这意味着上下文切换后,可以访问模拟的登录帐户在服务器内具有权限的任何资源。
The signature cannot be applied to context switches that are established through the stand - alone statements execute as user and execute as login 签名无法应用于通过独立的语句execute as user和execute as login建立的上下文切换。
While the context switch to the database user is active , any attempt to access resources outside the database will cause the statement to fail 当到数据库用户的上下文切换处于活动状态时,任何对数据库外部资源的访问尝试都会导致语句失败。
If we really wanted to eliminate the possibility of context switching , we would need to have more cpus on a system than processes running on that system 如果我们确实不希望出现任何上下文切换,则系统中的cpu数要大于该系统中运行的进程数。
In other words , the abstract purity of continuations is more interesting to me personally than is the context switch speedups of microthreads , for example 在本例中,热键的大小写都可以激活下拉菜单选项,并且可以使用enter键激活缺省选项。
