SQL Server の年からすべての開始日と終了日と週番号を取得する

@StartDate と @StartDate + @NumYears の間のすべての週のシリーズを生成します:

開始日と終了日は変更できますが、MAXRECURSION には注意してください。

CREATE FUNCTION fnWeek(@StartDate DATETIME)
RETURNS @Weeks TABLE (StartWeekDate DATETIME, EndWeekDate DATETIME, WeekOfYear int)
AS
BEGIN
    DECLARE @NumYears int = 2;

    ;WITH genDates  
    AS (
        SELECT @StartDate AS mdate
        UNION ALL
        SELECT DATEADD(week, 1, mdate) FROM genDates WHERE DATEADD(week, 1, mdate) < DATEADD(year, @NumYears, @StartDate)
    )
    INSERT INTO @Weeks
    SELECT mdate AS StartDate, DATEADD(day,6,mdate) AS EndDate, DATEPART(week, mdate) AS WeekOfYear
    FROM genDates OPTION (MAXRECURSION 0);

    RETURN;
END
GO 

select * from fnWeek('2016-01-01');

または @NumYears パラメータとして追加できます:

CREATE FUNCTION fnWeek(@StartDate DATETIME, @NumYears int)
RETURNS @Weeks TABLE (StartWeekDate DATETIME, EndWeekDate DATETIME, WeekOfYear int)
AS
BEGIN

    ;WITH genDates  
    AS (
        SELECT @StartDate AS mdate
        UNION ALL
        SELECT DATEADD(week, 1, mdate) FROM genDates WHERE DATEADD(week, 1, mdate) < DATEADD(year, @NumYears, @StartDate)
    )
    INSERT INTO @Weeks
    SELECT mdate AS StartDate, DATEADD(day,6,mdate) AS EndDate, DATEPART(week, mdate) AS WeekOfYear
    FROM genDates 
    OPTION (MAXRECURSION 0);

    RETURN;
END
GO 

select * from fnWeek('2016-01-01', 2);
