ご覧のとおり、BLA 列は 13 から始まります。1、2、3 などのように開始したいのですが、データにギャップがないようにしたいのです。ギャップがある理由は、すべての月が0その特定のためのものだからですbla

のすべての値を含む結果セットを取得するにはどうすればよいBLAです0か?

望ましい結果は次のとおりです。

ここに私のクエリがあります:

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

Answer 1

数値テーブルまたは1から192までのすべての値を持つテーブルを使用できます。そのテーブルを作成したり、ループまたは再帰CTEを使用して外出先で作成したり、システムビューの一部を使用したりできます。これは1つの例です。 ：

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

Answer 2

必要なもののデモを作成しました。Bla 列のいくつかのバージョンがあり、Bla3 は結果に表示される最終バージョンです。このクエリを簡単に変更して、テーブルで動作するようにすることができます。試してみてください。

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
