在分区内上移非空值

Question

不确定标题是否有意义，但这是我的问题以及如何到达当前位置。

背景：我在一对多设置中有2个表。 many表可以具有与该表关联的任何数量的记录，但是具有一个附加列，可以将该多行记录标识为介于1到7之间的任何值。 我用7个CTE来“收集”每组1-7的所有行，然后将它们连接到一个表上，使我到达示例数据的地步。

如果单个列中的所有行都为空，那么我想显示一个*，否则按GROUPID / GROUPNAME在每个列中显示所有不同的值。 我有些骇人听闻，并以一种告诫方式大幅度削减了获取自己想要的东西的方式。 如果可能的话，我想在GROUPID / GROUPNAME中分别对每一列进行排序，以使NULL不在数据中间。

这是使我陷入困境的代码：

WITH SAMPLEDATA (CYCLEID,GROUPID,GROUPNAME,COL1,COL2,COL3,COL4,COL5,COL6,COL7)
AS (
SELECT 1,7669,'000000261','GAS',NULL,NULL,NULL,'1',NULL,'00' FROM DUAL

所需的输出：

编辑这是在执行任何操作之前从我的示例中导入确切原始数据的代码。 从技术上讲，我需要将3个表捆绑在一起以破坏上面的输出。

GROUPPROFILE在上面的输出中保存了字段1-2中的ID和NAME。

COLVALUES根据COLLEVELID为1-7保留输出中其余字段的数据（NAME）

GROUPCOLMM表仅用于连接GROUPPROFILE.GROUPPROFILEID> COLVALUES.COLVALUEID

CREATE TABLE GROUPPROFILE (GROUPPROFILEID NUMBER(12), SHORTNM NVARCHAR2(30))
REM INSERTING into GROUPPROFILE
Insert into GROUPPROFILE (GROUPPROFILEID,SHORTNM) values (7669,'000000261');

您无法从发布的“原始”数据中获取样本数据。 我从子查询ORIGINALDATA中的样本数据中反向工程了原始数据，然后提出了以下解决方案：

WITH SAMPLEDATA (CYCLEID,GROUPID,GROUPNAME,COL1,COL2,COL3,COL4,COL5,COL6,COL7)
AS (
SELECT 1,7669,'000000261','GAS',NULL,NULL,NULL,'1',NULL,'00' FROM DUAL
UNION ALL
SELECT 2,7669,'000000261','GAS',NULL,NULL,NULL,'1',NULL,'000000261' FROM DUAL
UNION ALL
SELECT 3,7669,'000000261','GAS',NULL,NULL,NULL,'Chester',NULL,'00' FROM DUAL
UNION ALL
SELECT 4,7669,'000000261','GAS',NULL,NULL,NULL,'Chester',NULL,'000000261' FROM DUAL
UNION ALL
SELECT 5,7669,'000000261','GFG',NULL,NULL,NULL,'1',NULL,'00' FROM DUAL
UNION ALL
SELECT 6,7669,'000000261','GFG',NULL,NULL,NULL,'1',NULL,'000000261' FROM DUAL
UNION ALL
SELECT 7,7669,'000000261','GFG',NULL,NULL,NULL,'Chester',NULL,'00' FROM DUAL
UNION ALL
SELECT 8,7669,'000000261','GFG',NULL,NULL,NULL,'Chester',NULL,'000000261' FROM DUAL
UNION ALL
SELECT 9,7669,'000000261','GKE',NULL,NULL,NULL,'1',NULL,'00' FROM DUAL
UNION ALL
SELECT 10,7669,'000000261','GKE',NULL,NULL,NULL,'1',NULL,'000000261' FROM DUAL
UNION ALL
SELECT 11,7669,'000000261','GKE',NULL,NULL,NULL,'Chester',NULL,'00' FROM DUAL
UNION ALL
SELECT 12,7669,'000000261','GKE',NULL,NULL,NULL,'Chester',NULL,'000000261' FROM DUAL
 ) 
, originaldata as (
  select distinct groupid, groupname, col, val from sampledata
  unpivot (val for col in (COL1 as 1,COL2 as 2,COL3 as 3,COL4 as 4,COL5 as 5,COL6 as 6,COL7 as 7))
)
select GROUPID, GROUPNAME, 
  case when rn = 1 and col1 is null then '*' else col1 end col1,
  case when rn = 1 and col2 is null then '*' else col2 end col2,
  case when rn = 1 and col3 is null then '*' else col3 end col3,
  case when rn = 1 and col4 is null then '*' else col4 end col4,
  case when rn = 1 and col5 is null then '*' else col5 end col5,
  case when rn = 1 and col6 is null then '*' else col6 end col6,
  case when rn = 1 and col7 is null then '*' else col7 end col7
from (
  select o.*,
  row_number() over(partition by groupid, groupname, col order by val) rn
  from originaldata o
)
pivot(
  max(val) 
  for col in (1 as COL1,2 as COL2,3 as COL3,4 as COL4,5 as COL5,6 as COL6,7 as COL7)
)
order by groupid, groupname, rn;

   GROUPID GROUPNAME COL1      COL2      COL3      COL4      COL5      COL6      COL7
