如何將表格行轉換爲特定組格式

Question

我有一個表格，並且我想以兩種格式輸出記錄。

在第一個輸出中，我希望表格行顯示爲左側和右側組，您可以在圖像中看到。 並在第二個輸出中我想要將行作爲一個左側和一個右側。

我正在使用SQL Server。

我曾嘗試與支點，但沒有成功。

如果你不得不做這樣的事情在T-SQL，這是做的一種方式......

DECLARE @ColBreak INT = 5 
;WITH MyTable (SrNo, ItemNo, Qty) AS 
(
    SELECT 1, 'A1', 150 UNION ALL 
    SELECT 2, 'A2', 100 UNION ALL 
    SELECT 3, 'A3', 300 UNION ALL 
    SELECT 4, 'A4', 150 UNION ALL 
    SELECT 5, 'A5', 100 UNION ALL 
    SELECT 6, 'A6', 300 UNION ALL 
    SELECT 7, 'A7', 150 UNION ALL 
    SELECT 8, 'A8', 100 UNION ALL 
    SELECT 9, 'A9', 300 UNION ALL 
    SELECT 10, 'A10', 150 
) 
,Column1 AS 
(
    SELECT * 
    FROM MyTable T1 
    WHERE SrNo <= @ColBreak 
) 
,Column2 AS 
(
    SELECT * 
    FROM MyTable T1 
    WHERE SrNo > @ColBreak 
) 
SELECT * 
FROM Column1 T1 
JOIN Column2 T2 ON T1.SrNo + @ColBreak = T2.SrNo
