想要将数据从两个单独的列显示到同一列中

Question

这是输入表：

子sku后面的父sku应该在同一列中。同样所有的产品。

我的代码无效。一种不同的方法可能有所帮助。

IF OBJECT_ID('tempdb..#tmp_table ') IS NOT NULL 
DROP TABLE #tmp_table ; 

select * into #tmp_table 
from 
(
select  distinct sku, 
        B.[Child SKU] as childSKU,
        C.[Parent SKU (PartNo) ] as parentSKU,
        A.UPC,A.OutOfStockMsg,
        A.Size 
from (
    select  [Child SKU] as sku,
            UPC,
            OutOfStockMsg,
            Size
    from stg_LazyOne_ChildSKU_Details
    union
    select  [Parent SKU (PartNo) ] as sku,
            UPC,OutOfStockMsg,
            Size
    from stg_LazyOne_ChildSKU_Details 
) A 
left join stg_LazyOne_ChildSKU_Details B 
    on A.sku = B.[Child SKU]                -- child
left join stg_LazyOne_ChildSKU_Details C 
    on A.sku = C.[Parent SKU (PartNo) ]     -- parent
where B.[Child SKU] is null or C.[Parent SKU (PartNo) ] is null
) M 

select * 
from #tmp_table a 

我想显示这样的输出（我的预期结果）

;WITH cte AS (
SELECT *
FROM (VALUES 
('M05L', 'M05', '840650030043', 'OUT OF STOCK', 'L'),
('M05M', 'M05', '840650030012', 'OUT OF STOCK', 'M'),
('M05S', 'M05', '840650030045', 'OUT OF STOCK', 'S'),
('B003L', 'B003', '840650030046', 'OUT OF STOCK', 'L'),
('B003M', 'B003', '840650030039', 'OUT OF STOCK', 'M'),

) as t([Child SKU], [Parent SKU (PartNo)], [UPC], [OutOfStockMsg], [Size])
)
, skuuu AS (
SELECT  [Child SKU] as sku,
        [Parent SKU (PartNo)] as parent_sku,
        CASE WHEN [Size] = 'L' THEN 'size_pj=Large'
             WHEN [Size] = 'M' THEN 'size_pj=Medium'
             WHEN [Size] = 'S' THEN 'size_pj=Small'
             ELSE '' END AS [Size]
FROM cte
)


SELECT  sku,
        [Size] as addituional_attributes,
        NULL as configurable_variations
FROM skuuu
UNION ALL
SELECT DISTINCT  [Parent SKU (PartNo)] as sku
        ,NULL
        ,STUFF((SELECT  '|sku='+s.sku +','+ s.[Size]  FROM skuuu s WHERE s.parent_sku = c.[Parent SKU (PartNo)]FOR XML PATH ('')),1,1,'')
FROM cte c
ORDER BY sku DESC

输出：
