内存队列

http://blog.csdn.net/pukuimin1226/article/details/17994277 后面好好去理解，多个线程时，用内存队列，先记录一下

Redis

 

1.查询用时语句

declare @begin_date datetime

declare @end_date datetime

select @begin_date = getdate()

<这里写上你的语句...>

select @end_date = getdate()

select datediff(ms,@begin_date,@end_date) as '用时/毫秒'

2.下面这种方法比较全面，将执行每个语句时采取的步骤作为行集返回，通过层次结构树的形式展示出来

set statistics profile on

set statistics io on

set statistics time on

go

<这里写上你的语句...>

go

set statistics profile off

set statistics io off

set statistics time off
