SQL 具有父 ID 和子 ID 的服务器层次结构
SQL Server hierarchy with parent id and child id
我想生成用红色表示的 'hierarchy id' 值。该值是层次结构中最低级别的 id。层次结构的最高级别是 'ALL Service Groups'，最低级别是 'LL800_GB05'。它们与 Parent ID 和 ID 有关。所附图片仅为样本集。
更新--我已经建立了关系和血统。现在我知道 Hierarchy.I 的最高成员想要为新列中的每一行关联最低的 childID。我厌倦了在 Parentid 和 ID 上进行内部连接，但没有完全锻炼。我尝试了交叉连接但没有锻炼。下面是插入的数据

如果您知道查询开头的最低后代，则向上遍历递归 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才能找到它。所以你必须 know/be 能够找出顶部 parent 或底部后代。
这个答案有效，但只是因为最低级别只有 1 个后代，这对我来说似乎不太可能！但这就是问题所在，当最低级别有超过 1 个后代时，您如何选择将哪个 heirarchyid 放在 parent 中？或者您是否希望复制 parent 等，巧合的是，在这种情况下，此查询会执行此操作。
;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
@Table t
INNER JOIN cteRecursive c
ON t.ParentId = c.Id
)
, cteLowestDecendent AS (
SELECT TOP 1 Id AS LowestDecendatId, GreatestAncestorId
FROM
cteRecursive
ORDER BY
Level DESC
)
SELECT`enter code here`
l.LowestDecendatId
,r.*
FROM
cteRecursive r
INNER JOIN cteLowestDecendent l
ON r.GreatestAncestorId = l.GreatestAncestorId
关于此 post 有一些有趣的技巧： 查看它们以了解有关在树上上下行走或一起创建不同类型的 heirarchyid 的更多详细信息。
我倾向于在层次结构中使用范围键。使用范围键（R1 和 R2），您可以 select and/or 聚合数据而无需递归查询。此外，您知道所有祖先 and/or 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，通常顶部节点的父节点为 null，但样本数据没有，因此在锚查询中我有 where ParentID=1105
Declare @Table table (id int,ParentID int,Name varchar(50))
Insert Into @Table (ID,ParentID,Name) values
(48039,1105,'All Services'),
(133686,48039,'Ntw Services'),
(133647,133686,'Ntwk voice Services'),
(133649,133647,'Ntwk VOIP'),
(48053,133649,'LL800_GB05'),
(999999,133649,'Dummy to Illustrate multiple children')
Declare @GetID int = 48053 -- Any Desired ID
;With cteOH (id,ParentID,Lvl,Name,SortSeq)
as (
Select id,ParentID,Lvl=1,Name,SortSeq = cast(concat(id,'>') as varchar(500)) from @Table where ParentID=1105
Union All
Select h.id,h.ParentID,cteOH.Lvl+1,h.Name ,SortSeq = cast(concat(cteOH.SortSeq,h.id)+'>' as varchar(500)) FROM @Table 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 HierarchyID = F.ID -- Added to to fullfill request
,B.R1 -- Included to Illustrate Range Keys
,C.R2 -- Included to Illustrate Range Keys
,A.Lvl -- Included to Illustrate Level of Node
,A.ID
,A.ParentID
,A.Name
From cteOH A
Join cteR1 B on (A.ID=B.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)
Returns
HierarchyID R1 R2 Lvl ID ParentID Name
48053 1 6 1 48039 1105 All Services
48053 2 6 2 133686 48039 Ntw Services

请注意我的虚拟 ID 未显示
现在在这个示例中，我加入了 Join cteR1 F 这样你就可以返回层次结构
@Matt 指出我误解了请求，所以我想找个机会来弥补自己并介绍 Range Key 技术。

根据您的要求。这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。
我还是不明白你所说的最低级别是什么意思。有许多最低级别。我添加了一个 IsParent 字段，它指示一个点是否是 parent/roll-up...零表示叶节点或底部节点。

Now, this is the cool part!

我在 NON-PARENT 或 table Co1_Trans
中的叶级别创建了一些随机数据
以下查询说明了如何通过范围键汇总数据
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
这里显示结果
现在，假设您只想显示级别 1 和级别 2。让我们使用与之前相同的查询，但添加一个 where 子句.. Where H.Lvl<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
...
我想生成用红色表示的 'hierarchy id' 值。该值是层次结构中最低级别的 id。层次结构的最高级别是 'ALL Service Groups'，最低级别是 'LL800_GB05'。它们与 Parent ID 和 ID 有关。所附图片仅为样本集。
更新--我已经建立了关系和血统。现在我知道 Hierarchy.I 的最高成员想要为新列中的每一行关联最低的 childID。我厌倦了在 Parentid 和 ID 上进行内部连接，但没有完全锻炼。我尝试了交叉连接但没有锻炼。下面是插入的数据

如果您知道查询开头的最低后代，则向上遍历递归 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才能找到它。所以你必须 know/be 能够找出顶部 parent 或底部后代。
这个答案有效，但只是因为最低级别只有 1 个后代，这对我来说似乎不太可能！但这就是问题所在，当最低级别有超过 1 个后代时，您如何选择将哪个 heirarchyid 放在 parent 中？或者您是否希望复制 parent 等，巧合的是，在这种情况下，此查询会执行此操作。
;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
@Table t
INNER JOIN cteRecursive c
ON t.ParentId = c.Id
)
, cteLowestDecendent AS (
SELECT TOP 1 Id AS LowestDecendatId, GreatestAncestorId
FROM
cteRecursive
ORDER BY
Level DESC
)
SELECT`enter code here`
l.LowestDecendatId
,r.*
FROM
cteRecursive r
INNER JOIN cteLowestDecendent l
ON r.GreatestAncestorId = l.GreatestAncestorId
关于此 post 有一些有趣的技巧：
我倾向于在层次结构中使用范围键。使用范围键（R1 和 R2），您可以 select and/or 聚合数据而无需递归查询。此外，您知道所有祖先 and/or 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，通常顶部节点的父节点为 null，但样本数据没有，因此在锚查询中我有 where ParentID=1105
Declare @Table table (id int,ParentID int,Name varchar(50))
Insert Into @Table (ID,ParentID,Name) values
(48039,1105,'All Services'),
(133686,48039,'Ntw Services'),
(133647,133686,'Ntwk voice Services'),
(133649,133647,'Ntwk VOIP'),
(48053,133649,'LL800_GB05'),
(999999,133649,'Dummy to Illustrate multiple children')
Declare @GetID int = 48053 -- Any Desired ID
;With cteOH (id,ParentID,Lvl,Name,SortSeq)
as (
Select id,ParentID,Lvl=1,Name,SortSeq = cast(concat(id,'>') as varchar(500)) from @Table where ParentID=1105
Union All
Select h.id,h.ParentID,cteOH.Lvl+1,h.Name ,SortSeq = cast(concat(cteOH.SortSeq,h.id)+'>' as varchar(500)) FROM @Table 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 HierarchyID = F.ID -- Added to to fullfill request

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

@Matt 指出我误解了请求，所以我想找个机会来弥补自己并介绍 Range Key 技术。

这里显示结果
现在，假设您只想显示级别 1 和级别 2。让我们使用与之前相同的查询，但添加一个 where 子句.. Where H.Lvl<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
