如何总结账户

我有 3 个表:DimAccounts、DimTime 和 FactBudget.

I have 3 tables: DimAccounts, DimTime and FactBudget.

DimAccounts 示例:

DimAccounts example:

AccountKey  Accouncode  AccountType   AccountFrom   AccountTo 
1.10001     10001       S                  11401    27601
1.10002     10002       S                  11401    16501
1.11000     11000       S                  11401    11508
1.110001    110001      B                   NULL    NULL
1.110002    110002      B                   NULL    NULL
1.11400     11400       S                  11401    11408

DimTime 示例:

DimTime example:

   TimeKey      FullDate
    20020102    2002-01-02
    20020103    2002-01-03
    20020104    2002-01-04

FactBudget 示例:

FactBudget example:

TimeKey     AccountKey              Debit    Credit
20080523    1.110002                0.00    884.00
20080523    1.110001                0.00    4251.96
20100523    1.100002                229.40  0.00
20080523    1.100002                711.79  0.00
20090523    1.110002                0.00    711.79
20080523    1.110001                0.00    229.40
20040523    1.100002                0.00    15619.05

事实上，Budget 有很多账户只有类型 B.我需要计算账户类型为 S(总和)的借方和贷方金额.AccountFrom 和 AccountTo 列显示 B 类帐户从哪里开始求和 (AccountFrom) 和哪里结束 (AccountTo).

In FactBudget are many Accounts just with type B. I need to calculate Debit and Credit Sums where Account type is S (Sum). Columns AccountFrom and AccountTo shows B Type Accounts from where to begin summing (AccountFrom ) and where end (AccountTo).

我已经使用 Cursors 制定了解决方案......但是你知道这很糟糕:) 我认为可以以某种方式对 FactBudget 中的数据进行分组(因为在 factbudget 中还有很多列和行 600k)以及在搜索解决方案时(当我只剩下 60k 行):

I have made solution using Cursors.... buth you know this is very bad :) I think there somehow to Group data in FactBudget (because there also many columns in factbudget and rows 600k) and when search for solution (when I group left just 60k rows):

SELECT [TimeKey], 
       [AccountKey], 
       SUM([Debit]), 
       SUM([Credit]) 
FROM   [dbo].[FactBudget] 
GROUP  BY [TimeKey], 
          [AccountKey]

那么，如何通过TimeKey和AccountKey获取S账户的借记和贷记金额?(AccountKey 数据类型为 nvarchar)

So, How to get S Accounts Debit and Cred Sum by TimeKey and AccountKey? (AccountKey datatype is nvarchar)

解决方案示例:

TimeKey     AccountKey  Debit    Credit
20080523    1.10002     0.00    2500
20080523    1.11000     0.00    8000
20080524    1.10002     900  0.00

实际上预算中没有类型为 S 的帐户！！！！我们需要得到它(例如 1.11000 仅适用于日期 20080523):

select 
SUM(Debit), SUM(Credit)
from FactBudget
LEFT JOIN [DimAccounts]
ON [DimAccounts].[AccountKey] = FactBudget.[AccountKey]   
where CAST([DimAccounts].AccountCode AS INT) >=11401    
and CAST([DimAccounts].AccountCode AS INT) <= 11508
and FactBudget.Timekey = 20080523

但我需要按日期显示每个 S 帐户的借记和贷记金额.

推荐答案

据我所知，您需要将 DimAccounts 加入到自身中，才能将 B 类帐户与其对应的 S 类帐户关联起来帐户，然后加入设置为 FactBudget 的那一行以最终获得数字.像这样:

As far as I can see, you need to join DimAccounts to itself to associate B-type accounts with their corresponding S-type accounts, then join that row set to FactBudget to finally obtain the figures. Something like this:

SELECT
  f.TimeKey,
  s.AccountKey,
  SUM(f.Debit) AS Debit,
  SUM(f.Credit) AS Credit
FROM DimAccounts s
  INNER JOIN DimAccounts b ON b.AccountCode BETWEEN s.AccountFrom AND s.AccountTo
  INNER JOIN FactBudget  f ON f.AccountKey = b.AccountKey
WHERE s.AccountType = 'S'
  AND b.AccountType = 'B'
GROUP BY
  f.TimeKey,
  s.AccountKey
