Before you can tune any database you must create a Transact-SQL script file trace file or trace table that contains a representative workload for the databases you want to tune .

优化任何数据库之前，必须先创建transact-sql脚本文件、跟踪文件或 跟踪 表，使其包含要优化的数据库的代表性工作负荷。

Create a new workload by deleting the loginname column from the events that were not tuned and then save only the untuned events in a new trace file or table .

通过从未优化的事件中删除loginname列来创建新的工作负荷，然后只将未优化的事件保存到新的 跟踪文件或 跟踪 表中。

Saving trace results to a table allows the same access as saving the trace to a file plus you can query the table to search for specific events .

将 跟踪结果保存到 表中后，可以与将跟踪保存到文件中后一样进行访问，另外还可以查询表以搜索特定事件。

The levels that are associated with diagnostic trace messages are defined in the following table .

与诊断 跟踪消息关联的级别在下 表中定义。

If the summary tables don 't display what you want then you can write your own trace processing tools on top of the text dump or the ( generally XML-based ) output of the command-line actions .

如果Xperf自带的summary table不能满足你的需要，你可以使用 Xperf处理工具得到这些事件的文本转储，或者Xperf命令的输出结果（一般是基于XML的），然后写自己的工具来进一步处理。

如果 跟踪模式没有被设为OFF（即默认情况），那么将使用下面的名称和格式，把每个入口、出口和非零SQL代码都记录到一个全局临时 表中

As trace elements play the important role in human they must be closely related to their physiological and biochemical functions and their nature to the positions in the periodic table of elements .

微量元素在人体内发挥着重要作用，它们的生理生化功能必然与其性质有关，而其性质与它们在元素周期 表中的位置有关。
