How to Distinct query result over 2 of 3 columns - sql

Question

I have a query like this:
WITH CTE_KELOMPOKINFORMASI (KelompokInformasi, XBRLItem_ItemId)
AS (
SELECT a.Id AS KelompokInformasi, c.XBRLItem_ItemId
FROM XBRLNamespaces a INNER JOIN XBRLHypercubes b
ON a.XBRLView_ViewId = b.XBRLView_ViewId
INNER JOIN XBRLHypercubeDimensionItems c
ON b.XBRLHypercubeId = c.XBRLHypercube_XBRLHypercubeId
WHERE a.Id like '%KBIK_AAKL%')
SELECT f.KelompokInformasi, e.Name AS DimensionName,
ROW_NUMBER() OVER(PARTITION BY e.Name ORDER BY e.Name DESC) AS 'Number'
FROM XBRLDefinitionRoleDomainItems a
LEFT OUTER JOIN XBRLDefinitionRoleDimensionItems b
ON a.XBRLDefinitionRole_DefinitionRoleId = b.XBRLDefinitionRole_DefinitionRoleId
LEFT OUTER JOIN XBRLItems c ON a.XBRLItem_ItemId = c.ItemId
LEFT OUTER JOIN XBRLLabels d ON a.XBRLItem_ItemId = d.XBRLItem_ItemId
LEFT OUTER JOIN XBRLItems e ON b.XBRLItem_ItemId=e.ItemId
LEFT OUTER JOIN CTE_KELOMPOKINFORMASI f ON b.XBRLItem_ItemId=f.XBRLItem_ItemId
WHERE b.XBRLItem_ItemId=f.XBRLItem_ItemId
and it gives result like this:
Kelompok Informasi DimensionName Number
KBIK_AAKL JWAAKT 1
KBIK_AAKL JWAAKT 2
KBIK_AAKL JWAAKT 3
KBIK_AAKL SNOUPL 1
KBIK_AAKL SNOUPL 2
KBIK_AAKL KOKOLT 1
KBIK_AAKL KOKOLT 2
KBIK_AAKL KOKOLT 3
KBIK_AAKL KOKOLT 4
Is it possible if i DISTINCT my result again by "DimensionName", so i have a result just like this:
KelompokInformasi DimensionName Number
KBIK_AAKL JWAAKT 1
KBIK_AAKL SNOUPL 2
KBIK_AAKL KOKOLT 3
i tried to do distinct like code below but it doesn't work
SELECT DISTINCT DimensionName
FROM (SELECT f.KelompokInformasi, e.Name AS DimensionName,
ROW_NUMBER() OVER(PARTITION BY e.Name ORDER BY e.Name DESC) AS 'Number'
FROM XBRLDefinitionRoleDomainItems a
LEFT OUTER JOIN XBRLDefinitionRoleDimensionItems b
ON a.XBRLDefinitionRole_DefinitionRoleId = b.XBRLDefinitionRole_DefinitionRoleId
LEFT OUTER JOIN XBRLItems c ON a.XBRLItem_ItemId = c.ItemId
LEFT OUTER JOIN XBRLLabels d ON a.XBRLItem_ItemId = d.XBRLItem_ItemId
LEFT OUTER JOIN XBRLItems e ON b.XBRLItem_ItemId=e.ItemId
LEFT OUTER JOIN CTE_KELOMPOKINFORMASI f ON b.XBRLItem_ItemId=f.XBRLItem_ItemId
WHERE b.XBRLItem_ItemId=f.XBRLItem_ItemId)

Answer 1

Use your distinct on the inner subquery and row number them on the outer Select
WITH CTE_KELOMPOKINFORMASI (KelompokInformasi, XBRLItem_ItemId)
AS (
SELECT a.Id AS KelompokInformasi, c.XBRLItem_ItemId
FROM XBRLNamespaces a INNER JOIN XBRLHypercubes b
ON a.XBRLView_ViewId = b.XBRLView_ViewId
INNER JOIN XBRLHypercubeDimensionItems c
ON b.XBRLHypercubeId = c.XBRLHypercube_XBRLHypercubeId
WHERE a.Id like '%KBIK_AAKL%')
Select A.*, ROW_NUMBER() OVER(ORDER BY A.DimensionName DESC) AS 'Number'
FROM (
SELECT distinct f.KelompokInformasi, e.Name AS DimensionName
FROM XBRLDefinitionRoleDomainItems a
LEFT OUTER JOIN XBRLDefinitionRoleDimensionItems b
ON a.XBRLDefinitionRole_DefinitionRoleId = b.XBRLDefinitionRole_DefinitionRoleId
LEFT OUTER JOIN XBRLItems c ON a.XBRLItem_ItemId = c.ItemId
LEFT OUTER JOIN XBRLLabels d ON a.XBRLItem_ItemId = d.XBRLItem_ItemId
LEFT OUTER JOIN XBRLItems e ON b.XBRLItem_ItemId=e.ItemId
LEFT OUTER JOIN CTE_KELOMPOKINFORMASI f ON b.XBRLItem_ItemId=f.XBRLItem_ItemId
WHERE b.XBRLItem_ItemId=f.XBRLItem_ItemId
) AS A

Answer 2

Just Filter with Your Row_Number
Try like this
SELCT KelompokInformasi,DimensionName,ROW_NUMBER() OVER(ORDER BY (SELECT NULL)) AS 'NUMBER' FROM
(
SELECT f.KelompokInformasi, e.Name AS DimensionName,
ROW_NUMBER() OVER(PARTITION BY e.Name ORDER BY e.Name DESC) AS 'RN'
FROM XBRLDefinitionRoleDomainItems a
LEFT OUTER JOIN XBRLDefinitionRoleDimensionItems b
ON a.XBRLDefinitionRole_DefinitionRoleId = b.XBRLDefinitionRole_DefinitionRoleId
LEFT OUTER JOIN XBRLItems c ON a.XBRLItem_ItemId = c.ItemId
LEFT OUTER JOIN XBRLLabels d ON a.XBRLItem_ItemId = d.XBRLItem_ItemId
LEFT OUTER JOIN XBRLItems e ON b.XBRLItem_ItemId=e.ItemId
LEFT OUTER JOIN CTE_KELOMPOKINFORMASI f ON b.XBRLItem_ItemId=f.XBRLItem_ItemId
WHERE b.XBRLItem_ItemId=f.XBRLItem_ItemId
) AS T
WHERE RN = 1
(OR)
SELCT KelompokInformasi,DimensionName,ROW_NUMBER() OVER(ORDER BY (SELECT NULL)) AS 'NUMBER' FROM
(
SELECT f.KelompokInformasi, e.Name AS DimensionName,
FROM XBRLDefinitionRoleDomainItems a
LEFT OUTER JOIN XBRLDefinitionRoleDimensionItems b
ON a.XBRLDefinitionRole_DefinitionRoleId = b.XBRLDefinitionRole_DefinitionRoleId
LEFT OUTER JOIN XBRLItems c ON a.XBRLItem_ItemId = c.ItemId
LEFT OUTER JOIN XBRLLabels d ON a.XBRLItem_ItemId = d.XBRLItem_ItemId
LEFT OUTER JOIN XBRLItems e ON b.XBRLItem_ItemId=e.ItemId
LEFT OUTER JOIN CTE_KELOMPOKINFORMASI f ON b.XBRLItem_ItemId=f.XBRLItem_ItemId
WHERE b.XBRLItem_ItemId=f.XBRLItem_ItemId
GROUP BY f.KelompokInformasi, e.Name
) AS T
