MySQL的左連接和與彙總兩個表

Question

我堆在MySQL的語法，其中我有值

title_id | revenue | cost 
1 | 10 | 5 
2 10 5 
3 10 5 
4 10 5 
1 20 6 
2 20 6 
3 20 6 
4 20 6 

，然後我有值

title_id | interest 
1 | 10 
2 10 
3 10 
4 10 
1 20 
2 20 
3 20 
4 20 

我想加入表基金錶收入這兩表使用左連接和彙總這樣的價值觀：

SELECT R.title_id, 
    R.revenue, 
    R.cost, 
    F.interest 
FROM (SELECT title_id, 
      Sum(revenue) revenue, 
      Sum(cost) cost 
    FROM revenue 
    GROUP BY revenue.title_id with rollup) r 
    LEFT JOIN (SELECT title_id, 
        Sum(interest) interest 
       FROM fund 
       GROUP BY title_id with rollup) f 
      ON r.title_id = F.title_id; 

輸出：

title_id | revenue | cost | interest 
1 30 11 30 
2 30 11 30 
3 30 11 30 
4 30 11 30 
Total 120 44 null 

但我想輸出是：

title_id | revenue | cost | interest 
1 30 11 30 
2 30 11 30 
3 30 11 30 
4 30 11 30 
Total 120 44 120 

這可能嗎？ 由於之前

Answer 1

下面是詳細情況：

隨着給出的數據：

select a.title_id, sum(revenue), sum(cost),sum(interest) from 
(select a.title_id, sum(revenue) as revenue, sum(cost) as cost from 
(select 1 title_id, 10 revenue , 5 cost UNION all 
select 2, 10, 5 UNION all 
select 3, 10, 5 UNION all 
select 4, 10, 5 UNION all 
select 1, 20, 6 UNION all 
select 2, 20, 6 UNION all 
select 3, 20, 6 UNION all 
select 4, 20, 6) as a 
GROUP BY title_id) as a 

left JOIN 

(select title_id, sum(interest) as interest from 
(select 1 as title_id, 10 as interest UNION all 
select 2, 10 UNION all 
select 3, 10 UNION all 
select 4, 10 UNION all 
select 1, 20 UNION all 
select 2, 20 UNION all 
select 3, 20 UNION all 
select 4, 20) as b 
GROUP BY title_id) as b 
on a.title_id = b.title_id 
GROUP BY a.title_id 
with ROLLUP 

結果：

1 30 11 30 
2 30 11 30 
3 30 11 30 
4 30 11 30 
    120 44 120 

最終查詢結構：

select a.title_id, sum(revenue), sum(cost),sum(interest) from 
(select a.title_id, sum(revenue) as revenue, sum(cost) as cost from 
(select * from revenue) as a 
GROUP BY title_id) as a 

left JOIN 

(select title_id, sum(interest) as interest from 
(select * from fund) as b 
GROUP BY title_id) as b 
on a.title_id = b.title_id 
GROUP BY a.title_id 
with ROLLUP
