Tree Like Query On SQL Server - sql

Question

i have a query join 4 tables
SELECT
a.Id AS KelompokInformasi, d.Name AS Domain, d.Id AS Dimension, e.Text AS Description FROM XBRLNamespaces a
INNER JOIN Hypercubes b
ON a.XBRLView_ViewId = b.XBRLView_ViewId
INNER JOIN HypercubeDimensionItems c
ON b.XBRLHypercubeId = c.XBRLHypercube_XBRLHypercubeId
INNER JOIN Items d
ON c.XBRLItem_ItemId = d.ItemId
INNER JOIN Labels e
ON d.ItemId = e.XBRLItem_ItemId
WHERE a.Id like '%AAKX%'
the query result is
KelompokInformasi Domain Dimension Description
AAKX JWAAKT dim_JWAAKT Jangka Waktu Aset
AAKX KOKOLT dim_KOKOLT Kolektibilitas
AAKX SNOUPL dim_SNOUPL Status Operasional Usaha Pihak Lawan
AAKX is a parent from the other data in Domain, Dimension, and Description.
So, i want to change the query and in the end have an output query result like this:
KelompokInformasi Domain Dimension Description
AAKX NULL NULL NULL
NULL JWAAKT dim_JWAAKT Jangka Waktu Aset
NULL KOKOLT dim_KOKOLT Kolektibilitas
NULL SNOUPL dim_SNOUPL Status Operasional Usaha Pihak Lawan

Answer 1

I think you must use Group by with cube and having. Or grouping sets.

SELECT
'KelompokInformasi' =
CASE
WHEN a.Id like '%AAKX%' THEN a.Id
ELSE NULL
END,
'Domain' =
CASE
WHEN a.Id like '%AAKX%' THEN NULL
ELSE d.Name
END,
'Dimension' =
CASE
WHEN a.Id like '%AAKX%' THEN NULL
ELSE d.Id
END,
'Description' =
CASE
WHEN a.Id like '%AAKX%' THEN NULL
ELSE e.Text
END,
FROM XBRLNamespaces a
INNER JOIN Hypercubes b
ON a.XBRLView_ViewId = b.XBRLView_ViewId
INNER JOIN HypercubeDimensionItems c
ON b.XBRLHypercubeId = c.XBRLHypercube_XBRLHypercubeId
INNER JOIN Items d
ON c.XBRLItem_ItemId = d.ItemId
INNER JOIN Labels e
ON d.ItemId = e.XBRLItem_ItemId
WHERE a.Id like '%AAKX%'

You can use Common table Expression(CTE),ROW_NUMBER() and Same Case statement used as above:
WITH cte AS
SELECT
a.Id AS KelompokInformasi,d.Name AS DOMAIN,d.Id AS Dimension,e.Text AS Description ,
ROW_NUMBER() OVER (PARTITION BY a.Id ORDER BY a.ID) AS COL5
FROM XBRLNamespaces a
INNER JOIN Hypercubes b
ON a.XBRLView_ViewId = b.XBRLView_ViewId
INNER JOIN HypercubeDimensionItems c
ON b.XBRLHypercubeId = c.XBRLHypercube_XBRLHypercubeId
INNER JOIN Items d
ON c.XBRLItem_ItemId = d.ItemId
INNER JOIN Labels e
ON d.ItemId = e.XBRLItem_ItemId
WHERE a.Id LIKE '%AAKX%' )
SELECT CASE
WHEN COL5 >1 THEN NULL ELSE KelompokInformasi END AS KelompokInformasi,
CASE
WHEN COL5=1 THEN NULL ELSE DOMAIN END AS DOMAIN,
CASE
WHEN COL5=1 THEN NULL ELSE Dimension END AS Dimension,
CASE
WHEN COL5=1 THEN NULL ELSE Description END AS Description
FROM cte
