当CPU为100％时如何终止SQL Server上的查询
[英]How to kill queries on SQL Server when CPU is 100%
问题描述
Today I have launched a profiler on sql server, CPU went at 100% and I couldn't connect to the database to kill the query. 
今天，我在sql server上启动了探查器，CPU达到了100％，并且我无法连接到数据库以终止查询。
Is there a management console? 有管理控制台吗？ How can I use it to kill a query / process? 如何使用它杀死查询/进程？
