SQL SERVER 查看SQL语句IO,时间，索引消耗

1.查看SQL语句IO消耗

set statistics io on 
    select * from dbo.jx_order where order_time>'2011-04-12 12:49:57.580' 
set statistics io off

 



 

 2.查看SQL语句时间消耗

set statistics time on 

     select * from dbo.jx_order where order_time>'2011-04-12 12:49:57.580' 
set statistics time off



 

 3.查看SQL语句索引消耗

set statistics profile on 
       select * from dbo.jx_order

       where order_time>'2011-04-12 12:49:57.580' 
set statistics profile off
