查詢時間：

 declare @d datetime
set @d=getdate()
select * from conference where  type_code='0' and con_code=1 order by t_date desc
select [語句執行花費時間(毫秒)]=datediff(ms,@d,getdate())

呵呵  關于數據庫添加數據~~

declare @m int
     set @m=1
     while @m<=20
     begin
insert into conference(charge) values(cast(@j as varchar(2))）   
     set @m=@m+1
     end

更新什么的道理相同 呵呵~ 剛學會的~
