原理解释：

AutocaptureElapsedHighSQL作业每隔一分钟调用[usp_checkElapsedHighSQL]存储过程，而[usp_checkElapsedHighSQL]存储过程又会调用

sp_who3存储过程获取一些当前线上环境的信息，被记录到[ElapsedHigh]表里

ResetcheckElapsedHighSQLtbname作业会在每天的23点59分执行，调用[usp_Resettbname]存储过程， [usp_Resettbname]存储过程会将[ElapsedHigh]表

的表名修改为：表名+当天日期，例如：ElapsedHigh2015-6-19 ，这样就进行了归档

[usp_checkElapsedHighSQL] 存储过程有两种调用方式，一种是传入NULL，那么[usp_checkElapsedHighSQL] 存储过程就会抓取最耗时的那个session

如果传入spid，那么就会显示那个spid的session

--调用示例
--不提供参数，抓取最耗时的一个SQL
EXEC [MonitorElapsedHighSQL].[dbo].[usp_checkElapsedHighSQL] NULL

--提供sessionsid参数，抓取那个sessionid相关的SQL
EXEC [MonitorElapsedHighSQL].[dbo].[usp_checkElapsedHighSQL] NULL

效果

USE [sss]
GO

WHILE 1=1
BEGIN
DECLARE @test NVARCHAR(100)
SET @test='你好'
DECLARE @id int
SET @id=2
SELECT * FROM [sss].[dbo].[test] WHERE [id]=@id
EXEC [dbo].[aa] @test =@test
EXEC [dbo].[ab] @id=@id

END

SELECT * FROM [dbo].[ElapsedHigh]
go

可以看到，参数也能抓取到，一般依靠sys.dm_exec_sql_text视图和sys.[fn_get_sql]()视图是无法获取到参数的

SQL Server profiler也是，它是整个RPC和Statement去抓

而且还会抓取当时的XML执行计划，点击它就能显示图形化的执行计划，这样对分析当时语句的执行情况非常有帮助

如有不对的地方，欢迎大家拍砖o(∩_∩)o
