1. 查詢sql所消耗io效能


set statistics io on 
select * from t_his_card_log where fyid = '0301014'
set statistics io off


 2.檢視SQL語句時間消耗
set statistics time on 
     select * from dbo.jx_order where order_time>'2011-04-12 12:49:57.580' 
set statistics time off




 3.檢視SQL語句索引消耗
set statistics profile on 
       select * from dbo.jx_order
       where order_time>'2011-04-12 12:49:57.580' 
set statistics profile off
