sql ="Update Goods Set TypeId='"&CInt(Request.form("Typeid")&"',Name='"&Gname&"',Sn_Number='"&Request("number")&"',Posttime='"&now()&"',"&_&",SalePrice='"&Request("saleprice")&"',Producer='"&Request("producer")&"',"&_&",Package='"&Request("package")&"',"&_&",Content='"&rqtContent&"'
Where Id='"&CInt("id")"'"
