增加，我基本上要計數，然後組結合兩個表的計數，然後組

Question

我有兩個查詢（返回正確的結果）：

Select profileID, 
Count(*) as numTotal from replies 
GROUP BY profileID; 

結果：

profileID: 1,2,3 
numTotal: 10,1,1 

和

Select postedByID, 
Count(*) as numTotal from WIRL_01.posts 
Group by postedByID 

結果：

postedByID: 1,2,3 
numTotal: 13,4,3 

在這種情況下，我想分組profileID = postedByID。我嘗試以下，但無濟於事：

Select profileID, 
Count(*) as numTotal 
from replies 
INNER JOIN posts ON replies.profileID = posts.postedByID 
Group by profileID 

結果：

postedByID: 1,2,3 
numTotal: 130,4,3 

任何指導，將不勝感激。

編輯：

這個查詢得到我一點點接近但是我怎麼組的結果通過配置文件ID？

Select profileID, Count(*) from WIRL_01.replies Group by profileID 
UNION ALL 
Select postedByID, Count(*) from WIRL_01.posts Group by postedByID 

給我...

配置文件ID：1,2,3,1,2,3 COUNT（*）：10,1,1,13,4,3

我需要的是：

配置文件ID：1,2,3 COUNT（*）：23,5,4

Answer 1

明白了！ :)

Select profileID, sum(count) as totalNum from (Select profileID, Count(*) as count from replies Group by profileID 
UNION ALL 
Select postedByID, Count(*) as count from posts Group by postedByID) as numTotal 
group by profileID
