Question

我们有5个级别的组织，从下到上将是（单位 - ＆gt;部分 - ＆gt;部门（部门） - ＆gt;总部（GDep） - ＆gt;部门）

我需要的是让所有组织的GDep低于GDep。

所以，如果我们有这个表

Child     Parent
--------  --------
Unit1     Section1
Unit2     Section1
Unit3     Dep1
Unit4     GDep1
Section1  GDep1
Dep1      GDep2
GDep1     Sector1
GDep2     Sector1

我需要查询结果

Child     Parent
--------  --------
Unit1     GDep1
Unit2     GDep1
Unit3     GDep2
Unit4     GDep1
Section1  GDep1
Dep1      GDep2

这是原始查询

    select DISTINCT HAOU_PARENTS.ORGANIZATION_ID, HAOU_PARENTS.NAME, HAOU_PARENTS.TYPE, HAOU_CHILDS.ORGANIZATION_ID, HAOU_CHILDS.NAME,  HAOU_CHILDS.TYPE, SYS_CONNECT_BY_PATH(HAOU_CHILDS.NAME, '#'), LEVEL
FROM per_org_structure_elements POSE
    JOIN hr_all_organization_units HAOU_PARENTS ON (POSE.ORGANIZATION_ID_PARENT = HAOU_PARENTS.ORGANIZATION_ID)
    JOIN hr_all_organization_units HAOU_CHILDS ON (POSE.ORGANIZATION_ID_CHILD = HAOU_CHILDS.ORGANIZATION_ID)
WHERE 1=1
    AND pose.org_structure_version_id = 2061
START WITH UPPER(HAOU_PARENTS.TYPE) = 'GDEP'
    CONNECT BY PRIOR POSE.ORGANIZATION_ID_CHILD = POSE.ORGANIZATION_ID_PARENT
ORDER BY 4
;

结果远离期望的输出，几乎是随机的。

＆＃34; per_org_structure_elements ＆＃34;包含组织层次结构，＆＃34; hr_all_organization_units ＆＃34;包含组织详细信息，如名称和类型。

假设您的表格有org_type列，该列使用您为各种组织级别描述的值，您可以执行以下操作：

select child, connect_by_root(child) as gdep
from your_table
where org_type in ('Unit', 'Section', 'Dep')
connect by parent = prior child
start with org_type = 'GDep';

The connect_by_root() clause为您提供来自层次结构根目录的子值，该值将是start with行的GDep。

由于层次结构未在任何地方定义（我们知道），您可以明确列出您想要包含的较低级别，但如果它定义得很明确，则不需要，因为孩子们应该“降低”＆＃39;反正。

使用CTE中的示例数据进行演示，并添加org_type值：

with your_table(child, parent, org_type) as (
            select 'Unit1', 'Section1', 'Unit' from dual
  union all select 'Unit2', 'Section1', 'Unit' from dual
  union all select 'Unit3', 'Dep1', 'Unit' from dual
  union all select 'Unit4', 'GDep1', 'Unit' from dual
  union all select 'Section1', 'GDep1', 'Section' from dual
  union all select 'Dep1', 'GDep2', 'Dep' from dual
  union all select 'GDep1', 'Sector1', 'GDep' from dual
  union all select 'GDep2', 'Sector1', 'GDep' from dual
)
select child, connect_by_root(child) as gdep
from your_table
where org_type in ('Unit', 'Section', 'Dep')
connect by parent = prior child
start with org_type = 'GDep';

CHILD    GDEP    
-------- --------
Section1 GDep1   
Unit1    GDep1   
Unit2    GDep1   
Unit4    GDep1   
Dep1     GDep2   
Unit3    GDep2

根据您添加的查询，相应的是（我认为，没有看到数据）：

connect_by_root(haou_parents.name) as gdep

根据您的样本提供更多补充数据：

with per_org_structure_elements(org_structure_version_id, organization_id_child,
    organization_id_parent) as (
            select 2061, 1, 5 from dual
  union all select 2061, 2, 5 from dual
  union all select 2061, 3, 6 from dual
  union all select 2061, 4, 7 from dual
  union all select 2061, 5, 7 from dual
  union all select 2061, 6, 8 from dual
  union all select 2061, 7, 9 from dual
  union all select 2061, 8, 9 from dual
),
hr_all_organization_units(organization_id, name, type) as (
            select 1, 'Unit1', 'Unit' from dual
  union all select 2, 'Unit2', 'Unit' from dual
  union all select 3, 'Unit3', 'Unit' from dual
  union all select 4, 'Unit4', 'Unit' from dual
  union all select 5, 'Section1', 'Section' from dual
  union all select 6, 'Dep1', 'Dep' from dual
  union all select 7, 'GDep1', 'GDep' from dual
  union all select 8, 'GDep2', 'GDep' from dual
  union all select 9, 'Sector1', 'Sector' from dual
)
select distinct haou_parents.organization_id,
  haou_parents.name,
  haou_parents.type,
  haou_childs.organization_id,
  haou_childs.name,
  haou_childs.type,
  sys_connect_by_path(haou_childs.name, '#') as path,
  connect_by_root(haou_parents.name) as gdep,
  level
from per_org_structure_elements pose
join hr_all_organization_units haou_parents
on (pose.organization_id_parent = haou_parents.organization_id)
join hr_all_organization_units haou_childs
on (pose.organization_id_child = haou_childs.organization_id)
where 1=1
and pose.org_structure_version_id = 2061
start with upper(haou_parents.type) = 'GDEP'
connect by prior pose.organization_id_child = pose.organization_id_parent
order by 4;

得
