我有这样的数据。如果我选择开始日期：“ 2018-06-25”和结束日期：“ 2018-07-01”。我应该从那周得到数据。如果选择一周中的任何起始日期和结束日期。我应该得到那几周的数据。示例开始日期：“ 2018-06-28”和结束日期：“ 2018-07-09”。如果我选择开始日期：“ 2018-06-25”和结束日期：“ 2018-07-11”。我应该得到三个星期的数据。这可能吗？

Answer 1

SELECT * FROM yourTable WHERE start_date::date > '2018-06-25' and end_date::date < '2018-07-01'

Answer 2

您应该在Start_date:'2018-06-28' and end_date:'2018-06-09'子句中使用>=和<=而不是where，它看起来像这样：

select * from your_table where Start_date >= '2018-06-09' and end_date <= '2018-06-28'

根据不同的星期开始和结束日期获取数据
