Question

我有关于SQL查询的问题。现在我有GETDATE（）例如今天是星期三，我需要在星期一晚上之间约会。和GETDATE（）将在这两个日期

今天的例子是星期四18.05.2017我希望日期在15.05.2017和22.05.2017之间

我无法找到任何解决方案。如何在查询中的where语句中编写它。

SELECT * FROM MATCHES
WHERE ...

提前致谢

Answer 1

收到第一个星期一： SELECT DATEADD(ww, DATEDIFF(ww,0,GETDATE()), 0)

和第二个： SELECT DATEADD(ww, DATEDIFF(ww,0,GETDATE()) + 1, 0)

Answer 2

这是解决方案首先创建一个日历表，然后

declare @startDate datetime = dateadd(week, datediff(week, 0, getdate()), 0);
declare @endDate datetime = DATEADD(DAYS,7,@startDate)

SELECT  Date
FROM    dbo.Calendar
WHERE   Date >= @startDate 
AND     Date < @endDate ;

Answer 3

创建日历表（如果不存在）

IF EXISTS (SELECT * FROM information_schema.tables WHERE Table_Name = 
'Calendar' AND Table_Type = 'BASE TABLE')
BEGIN
   DROP TABLE [Calendar]
END

CREATE TABLE [Calendar]
(
   [CalendarDate] DATETIME
)

DECLARE @StartDate DATETIME
DECLARE @EndDate DATETIME
SET @StartDate = GETDATE()
SET @EndDate = DATEADD(d, 365, @StartDate)

WHILE @StartDate <= @EndDate
BEGIN
      INSERT INTO [Calendar]
      (
            CalendarDate
      )
      SELECT
          @StartDate

         SET @StartDate = DATEADD(dd, 1, @StartDate)
END

然后，使用以下查询获取输出

declare @start datetime = dateadd(week, datediff(week, 0, getdate()), 0);
declare @end datetime = DATEADD(DAY,8,@start)

SELECT [CalendarDate]
FROM Calendar
WHERE CalendarDate BETWEEN @start AND @end

sql两个星期一晚上之间
