关于sql的小玩意 sql server添加数据

查询时间：

declare @d datetimeset @d=getdate()select * from conference where; type_code='0' and con_code=1 order by t_date descselect [语句执行花费时间(毫秒)]=datediff(ms,@d,getdate())

呵呵; 关于数据库添加数据~~

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~ 刚学会的~
