SELECT @row_number := @row_number + 1 as rownum,dd.* FROM (select @row_number := 0)AS ss,作为一张表来单独查询作为序号返回 rownum 就是返回的 序号名
count(1) AS fdGreenCardCount 返回参数绿卡个数 返回参数用户真实姓名：u.fd_user_real_name as fdUserRealName
u.fd_user_identity AS fdUserIdentity 返回参数用户身份证
通过手机号来进行两张表的关联字段
SELECT @row_number := @row_number + 1 as rownum,dd.* FROM (select @row_number := 0)AS ss,
(SELECT count(1) AS fdGreenCardCount,u.fd_user_real_name as fdUserRealName,u.fd_user_identity AS fdUserIdentity FROM
tb_green_card g LEFT JOIN tb_marathon_userinfo u ON g.fd_user_phone = u.fd_user_phone
GROUP BY g.fd_user_phone ORDER BY fdGreenCardCount DESC LIMIT 10) dd
