你可以看到BLA列从13开始。我希望它从1开始，然后是2，然后是3等......我不希望数据有任何空白。存在差距的原因是因为特定0
bla
如何让结果集包含BLA的所有值，即使是那些会在几个月内产生0的值？
这是期望的结果：

这是我的疑问：
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 SUM(Sep) is not null THEN SUM(Sep) ELSE 0 end Sep,
CASE WHEN SUM(Oct) is not null THEN SUM(Oct) ELSE 0 end Oct,
CASE WHEN SUM(Nov) is not null THEN SUM(Nov) ELSE 0 end Nov,
CASE WHEN SUM(Dec) is not null THEN SUM(Dec) ELSE 0 end Dec,
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
答案 0 :(得分：3)
您可以使用数字表或某些具有1到192之间所有值的表。您可以使用循环或递归CTE创建该表，使用某些系统视图等进行创建。就是一个例子：
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

我创建了一个可能是你需要的东西的演示，它有几个版本的Bla列，Bla3是结果中显示的最终版本，你可以轻松修改这个查询以在你的桌面上工作，试试吧：
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,
