Declare @Transaction  table (AccountID varchar(50),Debit float,Credit float)
insert into @Transaction
select '1-1-1-1-1-1-1',15500,0 union all
select '1-1-1-1-2-1-1',   25000,       0 union all
select '1-1-1-1-2-1-2',15000,       0 union all
select '1-1-1-1-2-1-3',0,44980 union all

select '1-1-1-1-2-1-1',   0 ,          3900

Declare @Budget   table (Months varchar(10),AccountID varchar(50),Budget float)
insert into @Budget
select 'Jan','1-1-1-1-1-1-1',4000 union all
select 'Feb','1-1-1-1-1-1-1',4000 union all

select 'Feb','1-1-1-1-2-1-2',5200 union all
select 'March','1-1-1-1-2-1-2',9800

;with CTE as
(
select AccountID,sum(Budget ) BudgetAmount from @Budget group by AccountID
)
,cte1 as
(
select AccountID,sum(debit )debit ,sum(Credit) Credit from @Transaction group by AccountID
)
select a.AccountID,c.Title,a.BudgetAmount,b.debit-b.Credit [Transaction Amount] 
from cte a inner join cte1 b on a.AccountID=b.AccountID
inner join @Chart c on a.AccountID=c.AccountID

Answer 2

 SELECT A.AccountID
      , A.Title             
      , B.Budget AS BudgetAmount
      , T.TransactionAmount  
FROM Account A INNER JOIN  
(SELECT AccountID, SUM(Budget) AS Budget
 FROM BudgetTable
 GROUP BY AccountID) B
ON A.AccountID = B.AccountID
INNER JOIN 
(SELECT AccountID, SUM(Debit) - SUM(Credit)  AS TransactionAmount
 FROM TransactionTable 
 GROUP BY AccountID) T
ON A.AccountID = T.AccountID

查询

<强> SQLFiddleExmple

 SELECT A.AccountID
      , A.Title             
      , isnull(B.Budget,0) AS BudgetAmount
      , isnull(T.TransactionAmount, 0) AS TransactionAmount
FROM Account A cross apply
(SELECT SUM(Budget) AS Budget
FROM BudgetTable 
WHERE BudgetTable.AccountID = A.AccountID) B
cross apply
(SELECT SUM(Debit) - SUM(Credit)  AS TransactionAmount
FROM TransactionTable 
WHERE TransactionTable.AccountID = A.AccountID) T

结果：

|     ACCOUNTID |              TITLE | BUDGETAMOUNT | TRANSACTIONAMOUNT |
|---------------|--------------------|--------------|-------------------|
| 1-1-1-1-1-1-1 |   NEW BULDING ADD. |        12000 |            -11000 |

| 1-1-1-1-2-1-2 |         BED SHEETS |        17500 |             18800 |
| 1-1-1-1-2-1-3 | BLACK & SOFT BOARD |            0 |            -14980 |
