【问题描述】：

这是我（有史以来）提出的第一个问题。所以，请耐心等待我解释我的问题。

我有一个如下表，它为我提供了一些帐户的层次结构：

declare @AccountDefinitions table
    (
     AccountID int identity(1, 1)
                   primary key
                   not null,
     AccountNumber nvarchar(11) not null,
     AccountType nvarchar(1) not null,
     SumSign1 smallint,
     SumAccount1 nvarchar(11),
     SumSign2 smallint,
     SumAccount2 nvarchar(11),
     SumSign3 smallint,
     SumAccount3 nvarchar(11)
    )

如果对一个帐户求和（添加到另一个帐户），则父帐户位于 SumAccount1 中。因此，SumAccount1 可以再次在 AccountNumber 中找到。这是普通的父/子层次结构，可以使用 CTE 轻松解决，如多个解决方案中所述。然而，还有另外两个名为 SumAccount2 和 SumAccount3 的父列。这意味着一个帐户最多可以有三个父母。但有时只有两个父母或没有父母。在这种情况下 SumAccount3（和/或其他）将为 NULL。

基本上，现在我需要一个嵌套的 CTE 来处理这些可能导致多个不同路径的多个可能的父级。如果一个帐户有 3 个父级，并且每个父级又有 3 个父级，那么这个帐户可能已经有九个不同的路径可以添加。

这里有一些测试数据可供使用：

insert  into @AccountDefinitions
        (AccountNumber, AccountType, SumSign1, SumAccount1, SumSign2,
         SumAccount2, SumSign3, SumAccount3)

我现在的尝试是获得具有多个连接的嵌套层次结构。但这似乎不起作用。

with    Hierarchy(AccountNumber, ParentsPaths)
          as (
              select    ad1.AccountNumber,
                        cast(N'' as nvarchar(max))
              from      @AccountDefinitions as ad1
              where     ad1.SumAccount1 is null
              union all
              select    ad2.AccountNumber,
                        cast(case when h.ParentsPaths = N''
                                  then (cast(ad2.AccountNumber as nvarchar(max)))
                                  else (h.ParentsPaths + '.'
                                        + cast(ad2.AccountNumber as nvarchar(max)))
                             end as nvarchar(max))
              from      @AccountDefinitions as ad2
              inner join Hierarchy as h
                        on h.AccountNumber = ad2.SumAccount1
                           or h.AccountNumber = ad2.SumAccount2
                           or h.AccountNumber = ad2.SumAccount3
              where     ad2.SumAccount1 is not null
             )
    select  *
    from    Hierarchy
    order by len(ParentsPaths) desc
option  (maxrecursion 0)

最后，我需要获取所有帐户的列表以及将它们添加到其中的所有中间步骤，以便我可以将结果表与所有财务预订连接起来，并将所有值汇总在一起。

示例：对于 K07_1000，只有一个可能的路径是 K07_1000 加到 K07_O100，加起来是 K07_O200，最后是 K07_O250。为了能够加入这个，我需要结果：

Original | Mapped 
------------------- 
K07_1000 | K07_1000  <-- preserve the original posting
K07_1000 | K07_O100  <-- the one and only path
K07_1000 | K07_O200
K07_1000 | K07_O250
K07_1000 | K07_O300

如果我在预订表中加入此表，那么我将获得一个预订到帐户 K07_1000 四个结果预订：原始预订和另外三个（这将添加到汇总的父帐户中）。

对于帐户 K07_1010，它会更加困难，因为它可以采用四种不同的路径。

Original | Mapped 
------------------- 
K07_1010 | K07_1010   <-- the original posting
K07_1010 | K07_100    <-- first possible path
K07_1010 | K07_1000
K07_1010 | K07_O100
K07_1010 | K07_O200
K07_1010 | K07_O250
K07_1010 | K07_O300
K07_1010 | K07_101P   <-- second possible path
K07_1010 | K07_O101
K07_1010 | K07_O202
K07_1010 | K07_O251
K07_1010 | K07_O301
K07_1010 | K07_C130   <-- third possible path
K07_1010 | K07_C155    <- third path with sub path 1
K07_1010 | K07_C630    <- third path with sub path 2
K07_1010 | K07_C655    <- third path with sub path 2

我希望这是有道理的，有人可以提供帮助。

【问题讨论】：

您可以添加输出，例如 K07_1000 和 K07_1010 吗？
感谢您添加示例结果的建议。抱歉，我之前没有想到。我更改了问题以添加您提到的两个示例。当然希望这能让它更清楚。
1. K07_1010 -> K07_C130 -> K07_C155 为什么这不在您的结果中？ 2. K07_1010 -> K07_100 为什么这不在结果中？ 3. K07_1010 -> K07_101P -> K07_O202 -> K07_O251 -> K07_O301 这也不是结果。 4. K07_1010 -> K07_100 -> K07_1000 -> K07_O100 -> K07_O200 ->K07_O250 -> K07_O300 这也是
我意识到您在发帖前不久提到的缺失路径，并进行了适当的更改。现在，它应该完成了。

【解决方案1】：

拉尔夫，试试这个。我认为它正在工作：

with    Hierarchy
          as (
              select    ad1.AccountNumber,
                        SumAccount1,
                        SumAccount2,
                        SumAccount3
              from      @AccountDefinitions as ad1

              union all

              select    h.AccountNumber,
                        ad2.SumAccount1,
                        ad2.SumAccount2,
                        ad2.SumAccount3
              from      @AccountDefinitions as ad2
              inner join Hierarchy as h
                        on h.SumAccount1 = ad2.AccountNumber
                        or h.SumAccount2 = ad2.AccountNumber
                        or h.SumAccount3 = ad2.AccountNumber
             ),

cter 
  as(
     SELECT AccountNumber, AccountNumber AS SumAccount FROM @AccountDefinitions

     UNION

     select  AccountNumber,
             SumAccount1 as SumAccount   
     from    Hierarchy
     where  SumAccount1 is not null

     union

     select  AccountNumber,
             SumAccount2 as SumAccount   
     from    Hierarchy
     where SumAccount2 is not null

     union

     select  AccountNumber,
             SumAccount3 as SumAccount   
     from    Hierarchy
     where SumAccount3 is not null)

select * from cter
WHERE AccountNumber = 'K07_1010'
option  (maxrecursion 0)

【讨论】：

Giorgi，非常感谢您的回答。我已经做了一些测试，除了对帐户 K07_1010 的明显限制之外，它似乎工作正常。明天我会在没有这个限制的情况下检查更多（并且还将原始映射 K07_1010 添加到 K07_1010 似乎也丢失了）。但这些都只是小事。真正重要的是你已经能够破解它，这绝对是了不起的。谢谢你。所以，我会再做一些检查，一旦验证，就把它标记为已回答。
经过几次检查后，我可以说它按预期工作。再次感谢！
