如何查找 table 是否具有给定的日期范围

Question

我想查明 table 是否有在传递给查询的日期范围内的行。以下是MYTABLE中的数据。我正在使用 SQL 服务器

DISPLAY_START_DATE      DISPLAY_END_DATE
2022-02-02 00:00:00.000     2022-02-28 00:00:00.000
2022-02-02 00:00:00.000     2022-02-06 10:34:01.653
2022-02-01 00:00:00.000     2022-02-17 00:00:00.000
2022-02-07 00:00:00.000     2022-02-25 00:00:00.000

以下是我的查询

DECLARE @startdate AS datetime ='2022-02-01' 
DECLARE @enddate AS datetime ='2022-02-10'
SELECT * from MYTABLE mt
WHERE 
(mt.DISPLAY_START_DATE = @startdate and  mt.DISPLAY_END_DATE = @enddate)    OR
(mt.DISPLAY_START_DATE < @startdate and  mt.DISPLAY_END_DATE > @enddate)    OR
(mt.DISPLAY_START_DATE < @startdate and  mt.DISPLAY_END_DATE < @enddate)    OR
(mt.DISPLAY_START_DATE < @startdate and  mt.DISPLAY_END_DATE < @enddate and  
    mt.DISPLAY_END_DATE > @startdate)   OR
(mt.DISPLAY_START_DATE > @startdate and  mt.DISPLAY_END_DATE < @enddate) OR
(mt.DISPLAY_START_DATE > @startdate and mt.DISPLAY_START_DATE < @enddate and 
    mt.DISPLAY_END_DATE < @enddate)

这里只拉取对应以下数据的第二行

DISPLAY_START_DATE      DISPLAY_END_DATE
2022-02-02 00:00:00.000     2022-02-06 10:34:01.653

Answer 1

两个区间相交的条件是每个区间必须先于其他区间开始:

..
WHERE mt.DISPLAY_START_DATE <= @enddate AND @startdate <= mt.DISPLAY_END_DATE

Answer 2

如果你想 select 给定范围内的所有行，你可以尝试下面的查询：

DECLARE @startdate AS datetime ='2022-02-01' 
DECLARE @enddate AS datetime ='2022-02-10'

SELECT * from MYTABLE mt
WHERE 
(mt.DISPLAY_START_DATE between @startdate and @enddate and mt.DISPLAY_END_DATE between @startdate and @enddate)

或者如果您想要一个 where 条件 select table 中完全或部分在范围

中的所有行

SELECT * from MYTABLE mt
WHERE 
(mt.DISPLAY_START_DATE between @startdate and @enddate and mt.DISPLAY_END_DATE between @startdate and @enddate) or
(mt.DISPLAY_START_DATE <=@startdate and mt.DISPLAY_END_DATE >=@enddate) or
(mt.DISPLAY_START_DATE <=@startdate and mt.DISPLAY_END_DATE between @startdate and @enddate) or
(mt.DISPLAY_START_DATE between @startdate and @enddate  and mt.DISPLAY_END_DATE >=@enddate)
