使用JavaScript连接SqlServer数据库。执行CRUD操作。

插入和查询操作
function db()
  {   
    //活动编号
    var activeid = Request.Form("activeid");
    //用户名
    var username = Request.Form("username");
    //手机号码
    var mobile = Request.Form("mobile");

    var sql = "insert into user (activeid,userid,chrtel,dtappenddate) values("+activeid+","+userid+",'"+mobile+"',getdate())";
    rs.open(sql,conn);
                rs.close();
  conn.close();
  rs=null;
