这是我提出的第一个问题（永远）。所以，在我试图解释我的问题时请耐心等待。
我有一个如下表格，它给出了某个帐户的层次结构：
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)
)
如果帐户总结（添加到另一个帐户），则父帐户在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，可以通过多种解决方案中描述的CTE轻松解决。 然而，还有两个父列，名称为SumAccount2和SumAccount3。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父母。如果一个帐户有三个父母，而且每个父母都有另外三个父母，那么这个帐户可能已经有九个不同的路径。
以下是一些测试数据：
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。但这似乎没有做到这一点。
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添加它们的所有中间步骤，以便我可以将结果表与所有财务预订一起加入，并将所有值汇总在一起。
示例：对于K07_1000，只有一条可能的路径是K07_1000添加到K07_O100，它加起来为K07_O200，最后以K07_O250结尾。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
如果我在预订表上加入此表，那么我会在一个预订中记入K07_1000四个结果预订：原始和三个（这将添加到总计的父帐户）。
对于帐户K07_1010，它可能会更难，因为它可能需要四条不同的路径。
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。

拉尔夫，试试吧。我认为它有效：
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)
