查詢時(shí)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(zhí)行花費(fèi)時(shí)間(毫秒)]=datediff(ms,@d,getdate())

呵呵; 關(guān)于數(shù)據(jù)庫添加數(shù)據(jù)~~

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(xué)會(huì)的~
