Question

我的桌子上有8列，其中2列是To＆amp; From这些数据类型为datetime。我想在这两个字段上执行带有一些过滤器的选择查询。

现在看下面的例子

Record X = From "5 May" to  "18 May" 

Filter 1: from "5 May" to "5 May" … x should show 

Filter 2: from "10 May" to "10 May" … x should show

Filter 3: from "1 May" to "1 May" … x should NOT show

Filter 4: from "19 May" to "19 May" … x should NOT show

Filter 5: from "18 May" to "18 May" … x should show 

Filter 6: From "4 May" to  "17 May" ….  X should show

Filter 7: From "4 May" to  "18 May" ….  X should show

Filter 8: From "4 May" to  "19 May" ….  X should show

Filter 9: From "5 May" to  "17 May" ….  X should show

Filter 10: From "5 May" to  "18 May" ….  X should show

Filter 11: From "5 May" to  "19 May" ….  X should show

Filter 12: From "2 May" to  "3 May" ….  X should NOT show

Filter 13: From "20 May" to  "25 May" ….  X should NOT show

所以基本上逻辑是如果过滤日期范围和数据库日期范围之间有任何日期，则记录应显示在结果中。

你能帮帮我吗？看到所有这些配置后我感到很困惑。

Answer 1

SELECT *
FROM YourTable
WHERE from >= '5/5/2014'
  AND from < '5/6/2014'
  AND to >= '5/5/2014'
  AND to < '5/6/2014'

不会像过滤器1一样简单吗？或者您是否需要1个查询中的所有过滤器？

Answer 2

您需要from或to列在过滤器定义的范围内，包括：

declare @filter_from datetime, @filter_to datetime

select *
from <table>
where col_from between @filter_from and @filter_to
  or col_to between @filter_from and @filter_to
  or @filter_from between col_from and col_to
  or @filter_to between vol_from and col_to

Answer 3

试试这个

Select * from table_name where startDate between '4 May' and '18 May'
And endDate between '5 May' and '19 May'

谢谢。希望这有帮助
