查詢時間：

declare @d datetimeset @d=getdate()select * from conference where; type_code='0' and con_code=1 order by t_date descselect [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 begininsert 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~
