樹狀查詢在SQL Server上

Question

我有一個查詢加入4桌

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%' 

查詢結果

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是從域，尺寸和描述其他數據的父母。

所以，我想改變查詢，並在年底有一個這樣的輸出查詢結果：

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

我認爲你必須與立方體，並具有使用組。或分組集。

Answer 2

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%' 

Answer 3

您可以使用使用公用表表達式（CTE），ROW_NUMBER（）和同一案件中陳述如上：

與CTE AS
選擇
a.Id AS KelompokInformasi，d.Name AS DOMAIN，d.Id AS Dimension，e.Text AS說明，
ROW_NUMBER（）OVER（由a.ID分隔a.Id）作爲COL5
FROM XBRLNamespaces一個
INNER JOIN超立方體b
ON a.XBRLView_ViewId = b.XBRLView_ViewId
INNER JOIN HypercubeDimensionItemsÇ
ON b.XBRLHypercubeId = c.XBRLHypercube_XBRLHypercubeId
INNER JOINÐ物品
ON c.XBRLItem_ItemId = d.ItemId
INNER JOIN標籤Ë
ON d.ItemId = e.XBRLItem_ItemId
WHERE a.Id LIKE '％AAKX％'）
SELECT CASE
WHEN COL5> 1 THEN ELSE NULL KelompokInformasi END AS KelompokInformasi，
CASE
WHEN COL5 = 1 THEN NULL ELSE DOMAIN END AS DOMAIN，
CASE
WHEN COL5 = 1 THEN NULL ELSE尺寸端爲尺寸，
CASE
WHEN COL5 = 1 THEN ELSE NULL說明END AS說明
FROM CTE
