--跟踪文件读入到表中分析
SELECT * INTO ZGSJY
FROM fn_trace_gettable('E:\wxxcdbprofiler.trc', default);
--某时间内，最耗时SQL
select TOP 100 SUBSTRING(Textdata,1,660) as '名称',
count(*) as '数量', sum(duration/1000) as '总执行时间ms',
       avg(duration/1000) as '平均执行时间ms',
       avg(cpu) as '平均CPU时间ms',
       avg(reads) as '平均读次数',
       avg(writes) as '平均写次数'
