如您所见，BLA 列从 13 开始。我希望它从 1 开始，然后是 2，然后是 3 等等......我不希望数据中有任何空白。存在差距的原因是因为所有月份都是0针对特定的bla

我如何让结果集包含 的所有值BLA，甚至是那些将0在几个月内产生的值？

这是期望的结果：

这是我的查询：

SELECT  CASE WHEN SUM(Jan) is not null THEN SUM(Jan) ELSE 0 end Jan,
        CASE WHEN SUM(Feb) is not null THEN SUM(Feb) ELSE 0 end Feb,
        CASE WHEN SUM(Mar) is not null THEN SUM(Mar) ELSE 0 end Mar,
        CASE WHEN SUM(Apr) is not null THEN SUM(Apr) ELSE 0 end Apr,
        CASE WHEN SUM(May) is not null THEN SUM(May) ELSE 0 end May,
        CASE WHEN SUM(Jun) is not null THEN SUM(Jun) ELSE 0 end Jun,
        CASE WHEN SUM(Jul) is not null THEN SUM(Jul) ELSE 0 end Jul,
        CASE WHEN SUM(Aug) is not null THEN SUM(Aug) ELSE 0 end Aug,

        CASE WHEN Bla > 191 THEN 192 ELSE Bla END Bla
FROM CTE
GROUP BY CASE WHEN Bla > 191 THEN 192 ELSE Bla END
order by bla

您可以使用数字表或具有从 1 到 192 的所有值的某个表。您可以创建该表，使用循环或递归 CTE 随时随地制作一个表，使用一些系统视图等。这是一个示例：

SELECT  ISNULL(SUM(Jan),0) Jan,
        ISNULL(SUM(Feb),0) Feb,
        ISNULL(SUM(Mar),0) Mar,
        ISNULL(SUM(Apr),0) Apr,
        ISNULL(SUM(May),0) May,
        ISNULL(SUM(Jun),0) Jun,
        ISNULL(SUM(Jul),0) Jul,
        ISNULL(SUM(Aug),0) Aug,
        ISNULL(SUM(Sep),0) Sep,
        ISNULL(SUM(Oct),0) Oct,
        ISNULL(SUM(Nov),0) Nov,
        ISNULL(SUM(Dec),0) Dec,
        A.RN Bla
FROM (  SELECT *, RN=ROW_NUMBER() OVER(ORDER BY object_id)
        FROM sys.all_objects) A
LEFT JOIN CTE B
ON A.RN = CASE WHEN B.Bla > 191 THEN 192 ELSE B.Bla END
WHERE A.RN BETWEEN 1 AND 192
GROUP BY A.RN
order by A.RN

我创建了一个演示，说明您可能需要什么，它有多个版本的 Bla 列，Bla3 是结果中显示的最终版本，您可以轻松修改此查询以在您的表上工作，试试看：

DECLARE @tbl TABLE (Jan INT, Feb INT, Mar INT, Apr INT, May INT, Jun INT, 
Jul INT, Aug INT, Sep INT, Oct INT, Nov INT, Dec INT, Bla INT)
INSERT @tbl VALUES 
(0,0,0,0,0,0,0,0,0,0,0,4,1),
(0,0,0,0,0,0,0,0,0,0,0,4,1),
(0,0,0,0,0,0,0,0,0,0,0,0,12),
(0,12,10,10,10,11,10,0,0,0,0,21,35),
(0,12,10,10,10,11,10,0,0,0,0,22,47),
(0,12,10,10,10,11,10,0,0,0,0,23,192),
(0,12,10,10,10,11,10,0,0,0,0,24,203)

;WITH a AS (
    SELECT  *, DENSE_RANK() OVER (ORDER BY Bla) Bla2
    FROM @tbl
),
b AS (
    SELECT  *, 
            CASE WHEN Bla > 191 THEN 192 ELSE Bla2 END Bla3
    FROM a
)

SELECT  ISNULL(SUM(Jan), 0) Jan,
        ISNULL(SUM(Feb), 0) Feb,
        ISNULL(SUM(Mar), 0) Mar,
        ISNULL(SUM(Apr), 0) Apr,
        ISNULL(SUM(May), 0) May,
        ISNULL(SUM(Jun), 0) Jun,
        ISNULL(SUM(Jul), 0) Jul,
        ISNULL(SUM(Aug), 0) Aug,
        ISNULL(SUM(Sep), 0) Sep,
        ISNULL(SUM(Oct), 0) Oct,
        ISNULL(SUM(Nov), 0) Nov,
        ISNULL(SUM(Dec), 0) Dec,
        Bla3
FROM    b
GROUP   BY Bla3
ORDER   BY Bla3
