asp 存贮过程 (SQL版asp调用存储过程)

存贮过程(SQL样版) 今天发个SQL存贮过程给大家认识 复制代码 代码如下:CREATEPROCEDURElogin_verify ( @community_idint,--拿值 @usernamevarchar(20), @passwordvarchar(40), @resulttinyintoutput ) AS setnocountON declare@service_deadline_datesmalldatetime,@community_setting_max_online_countint---定义一个变量为短日期格式 select@community_setting_max_online_count=community_setting_max_online_count,@service_deadline_date=service_deadline_datefromcommunity_infowherecommunity_id=@community_id--这里是求最大登录人数 ifdatediff(d,@service_deadline_date,getdate())>10--其实这个是限制用户的使用期,求当前日期与库中的记录日期如时大于10天,则返回@result=11 begin set@result=11--超过使用期 return end if(selectcount(*)fromonline_userwhere=@community_setting_max_online_count">community_id=@community_id)>=@community_setting_max_online_count--根据库中的记录设定与当前人数比较 begin set@result=10--超出在线人数限制--返回@result=10 return end declare@stamiaint,@last_update_stamia_datesmalldatetime,@level_idint--定义变量整型短日期型整型 declare@useridint,@user_roleint select@userid=userid,@user_role=user_role,@stamia=stamia,@last_update_stamia_date=last_update_stamia_date,@level_id=level_idfromuser_infowhereusername=@usernameandpassword=@passwordandcommunity_id=@community_idanduser_type=0 --从用户信息表中,将一些信息写入到定义的三个变量中 if@useridisnotnull----如果@userid不变null值 begin--用户名和密码校验成功 set@result=1--检验成功 return end else begin set@result=0---登录失败 end setnocountOFF GO我们给上面的过程取个名login_verify叫做 写成是ASP代码中调用安全认证的地方 '''事先已经定义好conn Setcmd.ActiveConnection=conn cmd.CommandText="login_verify" cmd.CommandType=&H0004 @community_idint,--拿值 @usernamevarchar(20), @passwordvarchar(40), @resultint cmd.Parameters.Appendcmd.CreateParameter("@community_id",3) cmd.Parameters.Appendcmd.CreateParameter("@username",200) cmd.Parameters.Appendcmd.CreateParameter("@password",200) cmd("@community_id")=session("community_id") cmd("@username")=request("userid") cmd("@password")=request("userid") cmd.execute dimresult result=cmd("@result") conn.close iftrim(result)="1"then '''''''''''''登录成功的提示与操作 else ''''''''''''''''''''''登录失败的提示与操作 endif
