轉換sql視圖輸出

Question

是否可以將1列的sql輸出格式化爲3列？

例如，我的電流輸出爲：

Column1 
    1 
    2 
    3 
    4 
    5 
    6 
    7 
    8 
    9 

這裏是我所要的輸出是：

Column1 Column2 Column3 
    1  2  3 
    4  5  6 
    7  8  9 

Answer 1

你可以用模數師做到這一點和ROW_NUMBER()功能：

;WITH cte AS (SELECT *,ROW_NUMBER() OVER(ORDER BY Column1) RN 
       FROM Table1) 
    ,cte2 AS (SELECT *,ROW_NUMBER() OVER(PARTITION BY RN%3 ORDER BY Column1) RN2       
       FROM cte) 
SELECT MAX(CASE WHEN RN%3 = 1 THEN column1 END) Col1 
     ,MAX(CASE WHEN RN%3 = 2 THEN column1 END) Col2 
     ,MAX(CASE WHEN RN%3 = 0 THEN column1 END) Col3 
     ,RN2 
FROM cte2 
GROUP BY RN2
