Question

有人可以通过以下方案帮助我吗？我正在使用SQL Server 2008r2。我需要sql server查询来获得预期的结果。这是我试图做的：

DECLARE @ProjectInvoice TABLE(InvoiceID INT, ProjectID INT, InvoiceAmount float)
DECLARE @ProjectBudget TABLE(ProjectBudgetID INT, ProjectID INT, BudgetAmount float)
INSERT INTO @ProjectBudget VALUES(11,1,100000),(12,1,50000)
INSERT INTO @ProjectInvoice VALUES (12345,1,25000)
,(12346,1, 30000) 
,(12347,1, 40000) 
,(12348,1, 30000)
,(12349,1, 10000)

select * from @ProjectBudget
select * from @ProjectInvoice

预期结果：

-- Expected Result
--InvoiceID ProjectID InvoiceAmount ProjectBudgetID BugetAmountLeft 
--  12345   1           25k         11              75k  -- > 100k(original budget) - 25k   
--  12346   1           30k         11              45k --> 75k( budget amount left after first invoice) - 30k
--  12347   1           40k         11              5k  --> 45k - 40k
--  12348   1           5k          11              0k  --> now only 5k is left budget, whereas we have 30k to deduct, deduct 5k from projectBudget11 
--  12348   1           25k         12              25k --> and the rest 25k from project Budget 12
--  12349   1           10k         12              15k

SELECT p.InvoiceID, p.ProjectID, p.InvoiceAmount, sm.ProjectBudgetID, 
sm.BudgetAmount - sm.amt AS runningTot
FROM @ProjectInvoice AS p
INNER JOIN (SELECT i.InvoiceID, b.projectBudgetID, b.BudgetAmount,
        SUM(i.InvoiceAmount) OVER (PARTITION BY b.ProjectBudgetID ORDER BY     
i.InvoiceId) AS amt
FROM @ProjectBudget AS b
INNER JOIN @ProjectInvoice AS i ON b.ProjectID = i.ProjectID) as sm ON p.InvoiceID = sm.InvoiceId
