是否可以按层次结构ID对层次结构中的sql数据进行排序,然后按字母顺序对每个级别排序进行排序?
所以说我们有一个Employees Table,它列出了基于Employees ID的组织层次结构
你有Bob(5)有Phil(17)和Charlie(28)向他报告,而Josie(6)有Tyler(15)和Mike(56)向她报告。
如果按HierarchyID排序,它将如下所示:
鲍勃(/ 5 /)但让它看起来像
可能更有意义鲍勃
--Charlie
--Phil
乔西
--Mike
--Tyler
如果没有它太复杂,这可能吗?

- 这会有用吗?这取自Sorting tree with other column in SQL Server 2008
DECLARE @table TABLE (id INT NOT NULL PRIMARY KEY, name NVARCHAR(4000) NOT NULL, path HIERARCHYID)
INSERT
INTO @table
VALUES
(1, 'People', '/'),
(2, 'Girls', '/1/'),
(3, 'Boys', '/2/'),
(4, 'Zoey', '/1/1/'),
(5, 'Kate', '/1/2/'),
(6, 'Monica', '/1/3/'),
(7, 'Mark', '/2/1/'),
(8, 'David', '/2/2/')
;WITH q AS
(
SELECT *, HIERARCHYID::Parse('/') AS newpath
FROM @table
WHERE path = HIERARCHYID::GetRoot()
UNION ALL
SELECT t.*, HIERARCHYID::Parse(q.newpath.ToString() + CAST(ROW_NUMBER() OVER (ORDER BY t.name) AS NVARCHAR(MAX)) + '/')
FROM q
JOIN @table t
ON t.path.IsDescendantOf(q.path) = 1
AND t.path.GetLevel() = q.path.GetLevel() + 1
)
SELECT replicate(convert(nvarchar, '-'), q.path.GetLevel()) + q.name /*+ '(' + q.newpath.ToString() + ')'*/
FROM q
ORDER BY
newpath

这是我找到的解决方案
declare @oldId hierarchyid, @newId hierarchyid, @parent hierarchyid
select @oldId = id_node, @parent = id_node.GetAncestor(1)
from gbs.T_Hierarchy_Activities ha
where ID = @ID_Object
select @newId = @oldId.GetReparentedValue(@oldId, ID_Node) from (
select row_number() over(order by id_node) rn, id_node
from gbs.T_Hierarchy_Activities ha
cross join (select * from common.FX_Permissions() where ID_Feature = 10) p
where ID_Node.IsDescendantOf(@oldId.GetAncestor(1)) = 1
and ID_Level = @oldId.GetLevel()
and ha.ID_Office = p.ID_Office
) a
where rn = @NewPosition
update gbs.T_Hierarchy_Activities
set ID_Node = case when ID_Node = @oldId then @newId else @oldId end
where ID_Node in (@oldId, @newId)

除非我误解了某些内容,否则您只需在ORDER BY
子句中添加辅助排序字段即可。例如:
SELECT * FROM Employees ORDER BY HierarchyID, Name
