Php 是否可以在一个查询中使用这两个mySQL查询？

我有两个mySQL查询，运行起来没有任何问题。第一个获取引用者，第二个计算国家/地区百分比和数字。但是，我需要在第一个查询中包含国家/地区%和数字，换句话说，如何将它们结合使用

SELECT *, COUNT(*) FROM track 
where referid='".$member."'
GROUP BY referer 
ORDER BY id desc limit 0,15


select id, country, num, num*100/total pct 
from (SELECT id,country, count(*) as num 
FROM track GROUP BY country 
ORDER BY num desc limit 3) x 
join (select count(*) total from track) y

---

与内联视图联接：

SELECT *, COUNT(*) FROM track t
where t.referid='".$member."'
GROUP BY t.referer 
ORDER BY t.id desc limit 0,15
JOIN
(
   select id, country, num, num*100/total pct 
   from (SELECT id,country, count(*) as num 
   FROM track GROUP BY country 
   ORDER BY num desc limit 3) x 
   join (select count(*) total from track) y
) tc on t.id = tc.id
