具有父ID和子ID的SQL Server层次结构
我想生成＆＃39;层次结构ID＆＃39;用红色表示的值。该值是层次结构中id的最低级别。最高级别的层次结构是“所有服务组”＆＃39;最低级别是＆＃39; LL800_GB05＆＃39;。它们与父ID和ID相关。附加的图像只是一个样本集。
更新 - 我已经形成了一种关系和血统。现在我知道Hierarchy的最高成员。我想关联新列中每行的最低childID。我厌倦了对Parentid和ID进行内部联接，但没有完全锻炼。我尝试了交叉连接，但没有锻炼。以下是插入数据

如果你知道查询开头的最低后代，那么请走一个递归的cte，这将使这更容易，更简单。如果您不知道最低级别，那么您需要沿着树走下去找到它。因此，您必须知道/能够找出顶级父级或底级后代。
这个答案有效但只是因为在最低级别只有一个后代似乎不太可能！但这就是问题，当最低级别有超过1个后代时，你会如何选择将哪个heirarchyid置于父级？或者你想要父母等被复制，在这种情况下，这个查询会巧合。
;WITH cteRecursive AS (
SELECT
GreatestAncestorId = Id
,Id
,ParentId
,Level = 0
FROM
@Table t
WHERE
ParentId = 1105
UNION ALL
SELECT
c.GreatestAncestorId
,t.Id
,t.ParentId
,Level = c.Level + 1
FROM

INNER JOIN cteRecursive c

)
, cteLowestDecendent AS (

答案 1 :(得分：0)
我倾向于在层次结构上使用范围键。使用范围键（R1和R2），您可以选择和/或聚合数据，而无需递归查询。此外，你知道所有的祖先和/或后代。现在，我通常使用范围键存储我的层次结构，并根据需要重建。
此技术可轻松支持可变深度（或锯齿状）层次结构。
在下面的示例中，通常顶级节点的父级为null，但示例数据没有，因此在锚点查询中我有其中ParentID = 1105
Declare @Table table (id int,ParentID int,Name varchar(50))
Insert Into @Table (ID,ParentID,Name) values
(48039,1105,'All Services'),

(133647,133686,'Ntwk voice Services'),
(133649,133647,'Ntwk VOIP'),
(48053,133649,'LL800_GB05'),

Declare @GetID int = 48053 -- Any Desired ID

Join cteR2 C on (A.ID=C.ID)
Join cteR1 F on (F.ID=@GetID and F.R1 between B.R1 and C.R2)
返回

答案 3 :(得分：0)
根据您的要求。以下是构建完整层次结构的代码 此结果是根据您在问题中提供的85行层次结构构建的。
我仍然不知道你的最低等级是什么意思。有许多最低级别。我添加了一个字段IsParent，它指示一个点是否为父/汇总...零表示一个叶子或底部节点。
;With cteOH (id,ParentID,Lvl,CID,SortSeq)
as (
Select id,ParentID,Lvl=1,CID,SortSeq = cast(concat(id,'>') as varchar(500)) from CO1 where ParentID=1105
Union All
Select h.id,h.ParentID,cteOH.Lvl+1,h.CID ,SortSeq = cast(concat(cteOH.SortSeq,h.id)+'>' as varchar(500)) FROM CO1 h INNER JOIN cteOH ON h.ParentID = cteOH.id
),
cteR1 as (Select id,SortSeq,r1=Row_Number() over (Order by SortSeq) From cteOH),
cteR2 as (Select A.id,r2 = max(B.r1) From cteOH A Join cteR1 B on (B.SortSeq Like A.SortSeq+'%') Group By A.id)
Select B.R1
,C.R2
,A.Lvl
,A.ID
,A.ParentID
,A.CID
,IsParent = iif(R1<>R2,1,0)
Into dbo.CO1_Hier -- << Storing Results of Hier For Ease of Use
From cteOH A
Join cteR1 B on (A.ID=B.ID)
Join cteR2 C on (A.ID=C.ID)
层次结构构建的结果
R1 R2 Lvl ID ParentID CID IsParent

现在，这是很酷的部分！
** 我在表Co1_Trans
中的NON-PARENT或叶级创建了一些随机数据以下查询说明了如何通过范围键
滚动数据Select H.R1
,H.R2
,H.Lvl
,H.ID
,H.ParentID
,H.CID
,H.IsParent
,NestedDesc = space((H.Lvl-1)*2)+H.CID
,Records = count(*)
,MinVal = min(SomeValue)
,MaxVal = max(SomeValue)
,AvgVal = Avg(SomeValue)
,SomeValue = sum(SomeValue)
,SomeOtherValue = sum(SomeOtherValue)
From dbo.CO1_Hier H
Join (Select _R1=B.R1,A.* From [dbo].[CO1_Trans] A Join dbo.CO1_Hier B on (A.ID=B.ID)) B
on (B._R1 between H.R1 and H.R2)
Group By H.R1
,H.R2
,H.Lvl
,H.ID
,H.ParentID
,H.CID
,H.IsParent
Order By H.R1
结果显示在这里
现在，假设您只想显示级别1和2.让我们使用与之前相同的查询，但添加一个where子句.. 其中H.Lvl＆lt; 3
...
,SomeOtherValue = sum(SomeOtherValue)
From dbo.CO1_Hier H
Join (Select _R1=B.R1,A.* From [dbo].[CO1_Trans] A Join dbo.CO1_Hier B on (A.ID=B.ID)) B on (B._R1 between H.R1 and H.R2)
Where H.Lvl<3
Group By H.R1
,H.R2
,H.Lvl
...
