在父子层次结构中获取总计和小计

Question

我有以下表格结构，我正在尝试获取总计和小计并显示值的汇总。

ChartOfAccounts(AccountNumber, AccountDescription, ParentAccountNumber, IsControlAccount)
Ledger(LedgerId, JournalId, AccountNumber, IsDebit, Amount)

我已经设法使用 CTE 来获得所需的父子关系，但我不确定如何使用它来获取汇总到父账户中的控制账户余额。

到目前为止，我已经设法将以下查询放在一起，这并不完全是我想要的 --> SQL Fiddle。当前查询似乎没有正确汇总和分组父子总数。 （我已经从小提琴中排除了年、月列）

描述问题的另一种方式是，所有控制帐户都应具有其子帐户的总数。

我需要的输出如下 （年、月、AccountNumber、AccountDescription、DebitBalance、CreditBalance、Balance）

|Account#|Acc Desc                                 | DR     | CR     | BAL    |

|12001   |Buyer  Receivables - Best Buy            |5000    |0       |5000    |

Answer 1

这是我想出的，并且能够非常接近匹配您想要的输出

WITH CTEAcc 
AS
(
    SELECT
        coa.accountDescription,coa.accountnumber,coa.accountnumber as parentaccount
        FROM ChartOfAccounts coa
  where iscontrolaccount=1
  union all select c.accountdescription, coa.accountnumber, c.ParentAccount 
    from chartofaccounts coa
    inner join cteacc c on coa.ParentAccountNumber=c.accountnumber

)

select parentaccount as [Account#], accountdescription as [Acc Desc], 
sum(case when isdebit=1 then amount else 0 end) as DR,
sum(case when isdebit=0 then amount else 0 end) as CR,
sum(case when isdebit=1 then amount else 0 end)-sum(case when isdebit=0 then amount else 0 end) as BAL
from (select c.accountdescription, c.accountnumber, 
      c.parentaccount, l.isdebit, l.amount 
      from cteacc c
left join ledger l
  on c.accountnumber=l.accountnumber
union all select c.accountdescription, 
      c.accountnumber, c.accountnumber as parentaccount, 
      l.isdebit, l.amount 
      from ChartOfAccounts c
      inner join ledger l
  on c.accountnumber=l.accountnumber where amount<>0) f
group by parentaccount, accountdescription
order by parentaccount

Answer 2

又一个变种。保留层次结构和 iscontrol 字段仅供参考。首先，它将帐户层次结构与每个帐户相关联（递归 cte）。然后，对于每个帐户，根据层次结构位置（以及它是否是控制帐户）计算该帐户的分类帐项目总和。最后，包装在另一个查询中以计算余额并从输出中剔除未使用的帐户。

WITH AccountHierarchy AS (

    SELECT AccountNumber
          ,AccountDescription
          ,CAST(AccountNumber AS VARCHAR(MAX))
             + '/' AS AccountHierarchy
          ,IsControlAccount
      FROM ChartOfAccounts
      WHERE ParentAccountNumber IS NULL

    UNION ALL

    SELECT c.AccountNumber
          ,c.AccountDescription
          ,CAST(h.AccountHierarchy  AS VARCHAR(MAX))
             + CAST(c.AccountNumber AS VARCHAR(MAX))
             + '/' AS AccountHierarchy
          ,c.IsControlAccount
      FROM ChartOfAccounts c
      INNER JOIN AccountHierarchy h ON (c.ParentAccountNumber = h.AccountNumber)
      WHERE ParentAccountNumber IS NOT NULL
)

SELECT AccountNumber
      ,AccountDescription
      ,AccountHierarchy
      ,IsControlAccount
      ,DR
      ,CR
      ,CASE WHEN (DR IS NULL AND CR IS NULL) THEN NULL
            ELSE COALESCE(DR, 0) - COALESCE(CR, 0)
            END AS BAL

  FROM (SELECT h.AccountNumber
              ,h.AccountDescription
              ,h.AccountHierarchy
              ,h.IsControlAccount

              ,(SELECT SUM(l.Amount)
                  FROM Ledger l
                  INNER JOIN AccountHierarchy hd ON (l.AccountNumber = hd.AccountNumber)
                  WHERE l.IsDebit = 1
                    AND (    (h.IsControlAccount = 1 AND hd.AccountHierarchy LIKE h.AccountHierarchy + '%')
                          OR hd.AccountHierarchy = h.AccountHierarchy)
               ) AS DR

              ,(SELECT SUM(l.Amount)
                  FROM Ledger l
                  INNER JOIN AccountHierarchy hd ON (l.AccountNumber = hd.AccountNumber)
                  WHERE l.IsDebit = 0
                    AND (    (h.IsControlAccount = 1 AND hd.AccountHierarchy LIKE h.AccountHierarchy + '%')
                          OR hd.AccountHierarchy = h.AccountHierarchy)
               ) AS CR

          FROM AccountHierarchy h
        ) x

  WHERE NOT(CR IS NULL AND DR IS NULL)
  ORDER BY AccountHierarchy

我将这个question 用作层次结构示例。

输出：

Answer 3

从您想要的输出开始，我提出了以下查询，该查询根据 ParentAccountNumber 对子帐户进行分组。仅需要子查询，因为我假设您想在汇总之前将任何 NULL 值转换为 0（在 SQL 中，NULL + 42 = NULL）。

with preresult as
(
    select acc.ParentAccountNumber as AccountNumber,
          acc.AccountDescription as "Acc Desc",
          ISNULL(ld.Amount, 0) as DR,
          ISNULL(lc.Amount, 0) as CR

    from ChartOfAccounts acc

    left outer join Ledger ld
    on (ld.AccountNumber = acc.AccountNumber AND ld.IsDebit = 1)

    left outer join Ledger lc
    on (lc.AccountNumber = acc.AccountNumber AND lc.IsDebit = 0)

    where acc.ParentAccountNumber is not null
)

select c.AccountNumber as "ACC",
      c.AccountDescription as "ACC DESC",
      sum(DR) as DR,
      sum(CR) as CR,
      sum(DR) - sum(CR) AS BL

from preresult p
join ChartOfAccounts c on (c.AccountNumber = p.AccountNumber)

group by c.AccountNumber, c.AccountDescription;

Answer 4

这似乎给了你想要的：

;WITH recurs
AS
(
    SELECT C.AccountNumber, C.IsControlAccount, C.ParentAccountNumber, C.AccountDescription, 
            COALESCE((SELECT SUM(Amount) FROM Ledger WHERE AccountNumber = C.AccountNumber and IsDebit = 1), 0) AS DR,
            COALESCE((SELECT SUM(Amount) FROM Ledger WHERE AccountNumber = C.AccountNumber and IsDebit = 0), 0) AS CR,
            COALESCE((SELECT SUM(CASE WHEN IsDebit = 0 THEN Amount * -1 ELSE Amount END) FROM Ledger WHERE AccountNumber = C.AccountNumber), 0) AS BAL
    FROM ChartOfAccounts C
    WHERE IsControlAccount = 0
    UNION ALL
    SELECT C.AccountNumber, C.IsControlAccount, C.ParentAccountNumber, C.AccountDescription,
            r.DR, r.CR, R.BAL
    FROM ChartOfAccounts C
    INNER JOIN recurs r
        ON r.ParentAccountNumber = c.AccountNumber
)
SELECT R.AccountNumber, R.AccountDescription, SUM(R.DR) AS DR, SUM(R.CR) AS CR, SUM(R.BAL) AS BAL
FROM recurs R
WHERE NOT (R.DR = 0 AND R.CR = 0 AND R.BAL = 0)
GROUP BY R.AccountNumber, R.AccountDescription
ORDER BY AccountNumber

结果：
