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
此上图中的红框可以看到此查询走了聚集索引扫描
