Question

我想将查询中的单列结果拆分为4列：

示例来源：（Select [FirstName from User）
彼得
玛丽
约翰
蒂娜
卡尔
简
比尔
萨拉

我想看起来像这样：

Column1   Column2   Column3   Column4  
Peter     Mary      John      Tina  
Carl      Jane      Bill      Sarah

Answer 1

您需要为ORDER BY添加一个唯一列才能获得确定性结果，但这些内容应该有效。

;WITH T
     AS (SELECT [FirstName],
                ( ROW_NUMBER() OVER (ORDER BY (SELECT 0)) - 1 ) / 4 AS Row,
                ( ROW_NUMBER() OVER (ORDER BY (SELECT 0)) - 1 ) % 4 AS Col
         FROM   [User])
SELECT [0] AS Column1,
       [1] AS Column2,
       [2] AS Column3,
       [3] AS Column4
FROM   T PIVOT (MAX(name) FOR Col IN ([0], [1], [2], [3])) P 
ORDER BY Row
