sql跟踪日志trc导入数据库的2种方法

转载自博客园.

第一种。使用函数导入到某个库中

A. 使用 fn_trace_gettable 从跟踪文件导入行

以下示例在 SELECT...INTO 语句的 FROM 子句内部调用 fn_trace_gettable。

USE AdventureWorks;
GO
SELECT * INTO temp_trc
FROM fn_trace_gettable('c:\temp\my_trace.trc', default);
GO

B. 使用 fn_trace_gettable 返回一个表，其中具有可以加载到 SQL Server 表中的 IDENTITY 列

以下示例在 SELECT...INTO 语句中调用该函数，并返回一个表，其中具有可加载到表 temp_trc 中的 IDENTITY 列。

USE AdventureWorks;
GO
SELECT IDENTITY(int, 1, 1) AS RowNumber, * INTO temp_trc
FROM fn_trace_gettable('c:\temp\my_trace.trc', default);
GO

第二种，使用Read80Trace工具完成（下载地址：http://www.microsoft.com/downloads/details.aspx?FamilyId=5691AB53-893A-4AAF-B4A6-9A8BB9669A8B&displaylang=en）

这种方法我在sql2005上没成功过，会报is not a valid 8.0 trace file format,错误，我想是因为2005是9.0版本引起的。

sql2000的话，成功了，使用下面的命令

Read80Trace -f -Slocalhost -Usa -Ppassword -Dtracedb -IE:\profiler\mytrace.trc

其中-f是关掉Read80Trace生成的rml文件，这个文件也很大，可以不用生成，我运行时就关掉了

-I是指定trc文件所在的位置，如果目录下面有mytrace_1.trc...mytrace_n.trc，Read80Trace会自动读取它们.

-Dtracedb是将把trace日志的数据载入的数据库名称，所以在-U时需要此用户具有创建数据的权限

-U -P就不用说了吧，注意命令的格式，-S和localhost中间没有空格

 

如果成功会在安装目录的的output目录下面生成以下文件

安装msxml4.0才能正常显示（我安装了6.0打不开），这个报表是这个存储过程执行结果

set QUOTED_IDENTIFIER ON

ALTER proc [dbo].[usp_GetAccessPattern]

as begin
/*首先得到全部语句的性能数据的总和*/

select @sum_total=count(*)*0.01,--这是所有语句的总数。
@sum_cpu=sum(cpu)*0.01, --这是所有语句耗费的CPU时间
@sum_reads=sum(reads)*0.01, --这是所有语句耗费的Reads数目，8K为单位。
@sum_writes=sum(writes)*0.01,--这是所有语句耗费的Writes数目，8K为单位。
@sum_duration=sum(duration)*0.01--这是所有语句的执行时间总和。
from tblBatches --这是Read80Trace产生的表，包括了Trace文件中所有的语句。
where duration>=@duration_filter --是否按照执行时间过滤
/*然后进行Group by，得到某类语句占用的比例*/
Select ltrim(str(count(*))) exec_stats,''+ str(count(*)/@sum_total,4,1)+'%' ExecRatio,
ltrim(str(sum(cpu)))+' : '++ltrim(str(avg(cpu))) cpu_stats,''+str(sum(cpu)/@sum_cpu,4,1)+'%' CpuRatio,

into #queries_staticstics from
/* tblUniqueBatches表中存放了所有标准化的语句。*/
(select reads,cpu,duration,writes,convert(varchar(2000),NormText)textdata from tblBatches
 inner join tblUniqueBatches on tblBatches.HashId=tblUniqueBatches.hashid where duration>@duration_filter
) B group by textdata --这个group by很重要，它对语句进行归类统计。
print 'Top 10 order by cpu+reads+duration'
select top 10 * from #queries_staticstics order by cp+rp+dp desc
print 'Top 10 order by cpu'
select top 10 * from #queries_staticstics order by cp desc
print 'Top 10 order by reads'
select top 10 * from #queries_staticstics order by rp desc
print 'Top 10 order by duration'
select top 10 * from #queries_staticstics order by dp desc
print 'Top 10 order by batches'
select top 10 * from #queries_staticstics order by tp desc
End

如果没有导入成功报错，大部分情况是因为列不够引起的，错误代码一般是这样
