统计分析SQL Server Profiler 追踪的SQL

统计分析SQL Server Profiler 跟踪的SQL

--跟踪文件读入到表中分析SELECT * INTO ZGSJYFROM fn_trace_gettable('E:\wxxcdbprofiler.trc', default);--某时间内，最耗时SQLselect 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'from ZGSJY group by substring(Textdata,1,660) order by sum(duration) desc

通过SQL Server Profiler 跟踪程序或者数据库运行过程中SQL的执行信息。然后分析sql耗时，从而明确优化点。
