獲取結果的MSSQL查詢

我有以下 sql 查詢

SELECT Stk_Conv_Id,Created_Date,DC_Code,SKU_Name,Grade,Stock_Qty,Stock_Conv_Ref_Code
  FROM [LEAFDB].[dbo].[Stock_Convertion_Tracking] a
  where a.Created_Date between '2021-12-31' and '2021-12-31 23:59:59'
  and DC_Code ='BNG'
  order by DC_Code, Stock_Conv_Ref_Code

下面給出的 SQL 查詢結果

Stk_Conv_Id Created_Date    DC_Code SKU_Name              Grade Stock_Qty   Stock_Conv_Ref_Code

我需要如下結果

Created_Date    DC_Code From_SKU              From_Grade From_Stk_Qty To_SKU              To_Grade To_Stk_Qty Final_Stock

您可以嘗試使用帶有ROW_NUMBER視窗函式的子查詢或 cte row number來獲取您的邏輯，SKU_Name然后使用條件聚合函式來獲取結果集。

查詢 1：

;with cte as (
  SELECT *,
         ROW_NUMBER () OVER(PARTITION BY Created_Date,DC_Code,Stock_Conv_Ref_Code,SKU_Name ORDER BY Stk_Conv_Id) rn
  FROM T1
), cte1 as (
  SELECT *,
         ROW_NUMBER () OVER(PARTITION BY Created_Date,DC_Code,Stock_Conv_Ref_Code ORDER BY Stk_Conv_Id)  grp
  FROM CTE 
  WHERE rn = 1
)
SELECT Created_Date,
       DC_Code, 
       max(case when grp = 1 then SKU_Name end) 'From_SKU',
       max(case when grp = 1 then Grade end) 'From_Grade',
       max(case when grp = 1 then Stock_Qty end) 'From_Stk_Qty',
       max(case when grp = 2 then SKU_Name end) 'To_SKU',
       max(case when grp = 2 then Grade end) 'To_Grade',
       max(case when grp = 2 then Stock_Qty end) 'To_Stk_Qty',
       max(case when grp = 1 then Stock_Qty end) - max(case when grp = 2 then Stock_Qty end) 'Final_Stock'
FROM cte1 
GROUP BY Created_Date,
       DC_Code,
       Stock_Conv_Ref_Code

結果：
