Trace-导出已有的服务器端跟踪
跟踪(Trace)常被我们用来检查性能问题。通常我们会有针对CPU、Duration、Reads的创建跟踪定义，这一类的脚本一般不会包含太多的事件和列，筛选条件也相对简单。假如某一天你使用GUI定义了一个包含大量事件和列的服务器端跟踪，点击运行后你直接把GUI关掉，而你却没有导出原始定义脚本。此时你想知道定义的筛选条件，或者定义的事件和列，甚至是希望另外创建一个相同的跟踪(你肯定不希望再次打开GUI设置繁琐的事件和列及筛选条件)。其实只要跟踪定义在SQL Server内部创建之后，你可以通过查询多个跟踪目录视图得到运行中的服务器端跟踪定义。
首先我们用Profiler创建一个跟踪，常规属性如下所示：
选择事件和列：
设置过滤条件：
事件选择设置好后，点击运行，此时Profiler如下所示：
查看sys.traces跟踪目录视图：
TraceID=2的是行集提供者跟踪，TraceID=3的是文件提供者跟踪
我们将行集提供者跟踪停止并移除：
--停止跟踪
exec sp_trace_setstatus 2, 0
--移除跟踪
exec sp_trace_setstatus 2, 2
移除后Profiler如下所示：
此时sys.traces跟踪目录视图只包含两条记录：
注意此时写入文件系统上的E:\Perfmon\StandardTrace.trc对应的服务器端跟踪还是在运行的。此时我们可以通过 文件|属性 来看看跟踪的定义，还可以通过 文件|导出|编写跟踪定义的脚本，并选择目标导出跟踪定义：
我们先导出跟踪定义StandardTrace.sql(后期对比)，然后将Profiter关闭。
用下面的脚本提取服务器端跟踪定义：

在我的机器上服务器端跟踪ID为3，因此在脚本的开始设置@TraceID = 3，按Ctrl+T再运行脚本，将结果复制粘贴到新建查询窗口，并删除首行虚线及末行影响行数，得到脚本如下：

如果发现注释的中文是乱码，请检查当前数据库的排序规则，或者用[N'中文']。此时的脚本还不能直接运行，我们需要将图中红框中的内容作适当调整：
调整为如下所示：

差异集中在事件和列顺序，以及筛选条件对null的处理。实际上两个脚本所定义跟踪完全相同。此时运行脚本，就能创建与StandardTrace.trc相同的跟踪了。
