如何加入三張表並按每人評論數量排序？

Question

我想大多數意見的基礎上，獲取從三個表中的數據接收到一個人，下面是我的表結構：

Table A 
ID | Follower | Comment | PLACE 
------------------------------- 
1 | ABC  | TEXT1 | LA 
3 | ABC  | TEXT1 | NY 
1 | ABC  | TEXT2 | LA 
2 | ABC  | TEXT1 | IL 
1 | ABC  | TEXT2 | LA 

Table B 
ID | NAME  | PLACE 
----------------------- 
1 | Name1 | LA 
2 | Name2 | IL 
3 | Name3 | NY 

Table C 
PLACE | COUNTRY 
----------------------- 
LA | US  
IL | US  
NY | US 

我所試圖做的是這樣的：

SELECT   
a.PLACE, a.ID, a.NAME, b.PLACE, Count(b.ID) AS CT, c.PLACE, c.COUNTRY 
FROM    
TableB AS a INNER JOIN 
TableA AS b ON a.ID = b.ID INNER JOIN 
TableC AS c ON b.PLACE = c.PLACE 
GROUP by b.ID 
ORDER BY (CT) DESC 

Answer 1

select b.ID,b.Name,b.Place,c.COUNTRY,a.MostComments 
from TableB b inner join 
(select ID,count(*) as MostComments from TableA 
group by ID) a 
on a.ID=b.ID 
inner join TableC c 
on b.PLACE=c.PLACE 
order by a.MostComments Desc
