Sql层次结构ID按级别排序

Question

是否可以按层次结构id对sql数据进行层次排序，然后对每个级别按字母顺序排序？

假设我们有一个Employees表，它根据Employees ID列出组织层次结构

您有Bob (5)，Phil (17)和Charlie(28)向他汇报工作，Josie (6)让Tyler (15)和Mike (56)向她汇报工作。

如果您按HierarchyID对其进行排序，它将如下所示：

Bob (/5/)

--菲尔(/5/17/)

--查利(/5/28/)

乔西(/6/)

--泰勒(/6/15/)

--Mike (/6/56/)

但是让它看起来像这样更有意义

鲍勃

--查利

--菲尔

乔西

--迈克

--泰勒

这有可能在不让它变得太复杂的情况下实现吗？

--这行得通吗？这张图片取自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

Answer 2

这就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)

除非我误解了什么，否则您可以在ORDER BY子句中添加一个辅助排序字段。例如：

SELECT * FROM Employees ORDER BY HierarchyID, Name
