如何在每月明智的报告中保持运行余额

Question

SELECT * 
FROM
    (SELECT 
        YEAR (DateOfTransaction) AS year,
        LEFT(DATENAME(MONTH, DateOfTransaction), 3) AS month,
        SUM(CASE WHEN TransTypeName LIKE 'credit%' THEN amount ELSE 0 END) - 
            SUM(CASE WHEN TransTypeName LIKE 'Debit%' THEN amount ELSE 0 END) AS Balance 
     FROM 
        .............) AS t
PIVOT (SUM(balance) FOR month IN (jan, feb, march, ...., Dec)) AS pvt

此查询returns按月报告帐户余额。我想要的结果是运行余额。

示例：

一月我贷5000，二月我贷2000

我的查询结果是

 year  jan   feb march...dec
 2014  5000  2000 null ..null

我想要这样的结果：

 year  jan   feb     march...dec
 2014  5000 7000     null ..null 
           (5000+2000)

Answer 1

试试这个

SELECT year,Jan = Jan, Feb = isnull(Jan,0)+isnull(Feb,0),....
FROM
    (SELECT 
        YEAR (DateOfTransaction) AS year,
        LEFT(DATENAME(MONTH, DateOfTransaction), 3) AS month,
        SUM(CASE WHEN TransTypeName LIKE 'credit%' THEN amount ELSE 0 END) - 
            SUM(CASE WHEN TransTypeName LIKE 'Debit%' THEN amount ELSE 0 END) AS Balance 
     FROM 
        .............) AS t
PIVOT (SUM(balance) FOR month IN (jan, feb, march, ...., Dec)) AS pvt)t

或者您可以简单地添加一个临时文件 table 来存储从 1 到 12 的数字

inner join #temp on n>=datepart(mm,DateofTransaction) group by year(transaction), n
