2つの日付の間に欠落している日付を挿入するための集計表？ SQL

    サンプルデータ 

    DECLARE @StartDate date = '2016-06-01';
DECLARE @EndDate   date = '2016-07-01';

DECLARE @Table_One TABLE (
    Staff_ID int, 
    dt date, 
    First_Name nvarchar(50), 
    Last_Name nvarchar(50), 
    Section  nvarchar(50), 
    Time_Worked datetime);

INSERT INTO @Table_One(Staff_ID, dt, First_Name, Last_Name, Section, Time_Worked) 
VALUES
(1001, '2016-06-01', 'Bill', 'Price ', 'Level 1', '2016-06-01 8:30:00.000'),
(1001, '2016-06-05', 'Bill', 'Price ', 'Level 1', '2016-06-05 8:30:00.000'),
(1001, '2016-06-09', 'Bill', 'Price ', 'Level 1', '2016-06-09 8:30:00.000'),
(1001, '2016-06-12', 'Bill', 'Price ', 'Level 1', '2016-06-12 8:30:00.000'),
(1002, '2016-06-01', 'Mary', 'Somers', 'Level 1', '2016-06-01 8:30:00.000'),

(1002, '2016-06-08', 'Mary', 'Somers', 'Level 1', '2016-06-08 8:30:00.000'),
(1003, '2016-06-03', 'Mark', 'Jones ', 'Level 1', '2016-06-03 8:30:00.000'),
(1003, '2016-06-05', 'Mark', 'Jones ', 'Level 1', '2016-06-05 8:30:00.000');

    クエリ

    クエリはCROSS APPLYを使用します 日付にギャップがある場合に行を「挿入」します。 Tallyを使用して、現在の行を必要な回数だけ複製します 数字の表。

    @StartDateの場合、特別な処理が行われます。 最初の行の日付の前です。そのため、2つのSELECTsがあります 一緒に結合しました。

    CTE.PrevDate IS NULL そのような行のみをフィルタリングし、必要な回数だけ繰り返されます。

    WITH
CTE
AS
(
    SELECT *
        ,LAG(dt) OVER (PARTITION BY Staff_ID ORDER BY dt) AS PrevDate
        ,LEAD(dt) OVER (PARTITION BY Staff_ID ORDER BY dt) AS NextDate
    FROM @Table_One AS T
)
SELECT
    Staff_ID
    ,NewDate
    ,First_Name
    ,Last_Name
    ,Section
    ,CASE WHEN NewDate = dt THEN Time_Worked ELSE NULL END AS Time_Worked
FROM
    CTE
    CROSS APPLY
    (
        SELECT DATEADD(day, Tally.ID - 1, CTE.dt) AS NewDate
        FROM dbo.Tally
        WHERE Tally.ID <= DATEDIFF(day, CTE.dt, ISNULL(CTE.NextDate, @EndDate))
    ) AS CA_Next

UNION ALL

SELECT

    ) AS CA_Prev
WHERE

ORDER BY Staff_ID, NewDate;

    生成された行を元のテーブルに挿入し直します

    最初は元のテーブルを変更したいと思っていなかったので、SELECTを作成しました。 必要な結果セットを返すクエリ。 INSERTに調整するのは簡単です 元のテーブルに新しい行を追加するクエリ。

    私がしたのは、フィルターWHERE NewDate <> dtを追加することだけです。 、これにより、以前は存在しなかった新しい行のみが挿入されます。

    WITH
CTE
AS
(
    SELECT
        Staff_ID
        ,dt
        ,First_Name
        ,Last_Name
        ,Section
        ,Time_Worked
        ,LAG(dt) OVER (PARTITION BY Staff_ID ORDER BY dt) AS PrevDate
        ,LEAD(dt) OVER (PARTITION BY Staff_ID ORDER BY dt) AS NextDate
    FROM @Table_One AS T
)
INSERT INTO @Table_One(Staff_ID, dt, First_Name, Last_Name, Section, Time_Worked) 
SELECT
    Staff_ID
    ,NewDate
    ,First_Name
    ,Last_Name
    ,Section
    ,NULL AS Time_Worked
FROM
    CTE
    CROSS APPLY
    (
        SELECT DATEADD(day, Tally.ID - 1, CTE.dt) AS NewDate
        FROM dbo.Tally
        WHERE Tally.ID <= DATEDIFF(day, CTE.dt, ISNULL(CTE.NextDate, @EndDate))
    ) AS CA_Next
WHERE
    NewDate <> dt

UNION ALL

SELECT
    Staff_ID
    ,NewDate
    ,First_Name
    ,Last_Name
    ,Section
    ,NULL AS Time_Worked
FROM
    CTE
    CROSS APPLY
    (
        SELECT DATEADD(day, - Tally.ID, CTE.dt) AS NewDate
        FROM dbo.Tally
        WHERE Tally.ID <= DATEDIFF(day, @StartDate, CTE.dt)
    ) AS CA_Prev
WHERE 
    CTE.PrevDate IS NULL

ORDER BY Staff_ID, NewDate;

    結果

    結果を確認するには、SELECTだけです。 元のテーブルのすべて。

    SELECT * FROM @Table_One ORDER BY Staff_ID, dt;

    結果は上記と同じです。
