Question

我有一张包含以下内容的表：

StartDate, EndDate, StartTime, EndTime

我希望能够在每个StartDate:StartTime and EndDate:EndTime之间生成时间戳。

StartDate 2017-01-01 
StartTime 07:20:00 
EndDate 2017-01-15 
EndTime 15:00:00.

我希望在2017-01-01 07:20和2017-01-01 15:00之间生成每分钟，但是对于2017-01-01和2017-01-15之间的每个日期。任何帮助将不胜感激。谢谢

这是你正在寻找的吗？

DECLARE
    @StartDate DATE = '2017-01-01',
    @StartTime TIME(0) = '07:20:00',
    @EndDate DATE = '2017-01-15',
    @EndTime TIME(0) = '15:00:00';


DECLARE 
    @BegDT DATETIME2(0) = CAST(CONCAT(@StartDate, ' ', @StartTime) AS DATETIME2(0)),
    @EndDT DATETIME2(0) = CAST(CONCAT(@EndDate, ' ', @EndTime) AS DATETIME2(0));

WITH 
    cte_n1 (n) AS (SELECT 1 FROM (VALUES (1),(1),(1),(1),(1),(1),(1),(1),(1),(1)) n (n)), 
    cte_n2 (n) AS (SELECT 1 FROM cte_n1 a CROSS JOIN cte_n1 b),
    cte_n3 (n) AS (SELECT 1 FROM cte_n2 a CROSS JOIN cte_n2 b),
    cte_Calendar (dt) AS (
        SELECT TOP (DATEDIFF(mi, @BegDT, @EndDT) + 1)
            DATEADD(mi, ROW_NUMBER() OVER (ORDER BY (SELECT NULL)) - 1, @BegDT)
        FROM
            cte_n3 a CROSS JOIN cte_n3 b
        )
SELECT 
    c.dt
FROM
    cte_Calendar c
WHERE 
    CAST(c.dt AS TIME(0)) BETWEEN @StartTime AND @EndTime;
