Question

我的记录如下

StartDate    | EndDate    | ID
---------------------------------
25-12-2016     30-12-2016    0 
01-01-2017     05-01-2017    1
10-01-2017     12-01-2017    2
01-02-2017     05-02-2017    3

通过从 02-01-2017 选择日期范围直到 11-01-2017 ，我们如何选择介于两者之间的记录Startdate n EndDate按预期给出的日期范围？

希望表格结果如下

StartDate    | EndDate    | ID
------------------------------
01-01-2017     05-01-2017    1
10-01-2017     12-01-2017    2

Answer 1

所以，基本上你问的是如何检查两个日期范围是否重叠。这样做的方法是检查一个在另一个结束之前开始，而另一个在结束之前开始。您可以在overlap tag wiki.

您的查询应该是这样的：

SELECT StartDate, EndDate, ID
FROM YourTable
WHERE StartDate <= '11-01-2017'
AND EndDate >= '02-01-2017'

Answer 2

尝试以下查询，

DECLARE @V_START_DATE   DATETIME = '2017-01-02' 
        ,@V_END_DATE    DATETIME = '2017-01-11' 

SELECT  *
FROM    @TABLE
WHERE   StartDate   BETWEEN @V_START_DATE AND @V_END_DATE
    OR  EndDate     BETWEEN @V_START_DATE AND @V_END_DATE

Answer 3

尝试以下查询

SELECT * FROM DateRanges
WHERE StartDate BETWEEN '02-01-2017' and '11-01-2017'
OR ENDdate  BETWEEN '02-01-2017' and '11-01-2017'

从给定日期到日期选择记录。
