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：

-- 传入需要查看的TraceID
DECLARE @TraceID int
SET     @TraceID = 3

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。
执行后sys.traces跟踪目录视图就会包含三条记录：

补充：有没有不用手动调整筛选部分代码就可以直接得出与原跟踪定义完全相同的脚本。此脚本根据<Professional SQL Server 2008 Internals and Troubleshooting>中10.7.3章节作了部分调整得出。筛选部分用游标写了段代码可以直接得出，但要一次得到整个跟踪定义却不知道如何拼凑，暂时放上筛选部分的获取代码：
