Mysql SQL：按日期范围查找数据

我有两个记录，字段分别为“开始日期”和“结束日期”：

 - Record 1 : from_date=2017-05-15 and to_date=2017-06-12
 - Record 2 : from_date=2018-03-20 and to_date=2018-04-11

如果从日期开始搜索，如何获取记录2：

 - 2018-03-01 and 2018-03-31?

或

或

这很简单：

SELECT * 
   FROM records 
    WHERE from_date >= @from_date 
         OR to_date <= @to_date 

这表明您只需要一个bounderies来匹配

请注意，基于DBMS，日期比较可能会有所不同，但逻辑保持不变。

尝试以下示例：

Declare @date1 Date
Declare @date2 Date

set @date1 = <<give your first date>> 'yyyy-dd-mm
set @date2 = <<give your second date>> 'yyyy-dd-mm

SELECT * FROM tbldate WHERE CONVERT(DATE,@date1) BETWEEN from_date and to_date OR CONVERT(DATE,@date2) BETWEEN from_date and to_date

oracle示例：

with 
    table1 as 
      ( select 1 id, to_date('2017-05-15','YYYY-MM-DD') date_from, to_date('2017-06-12','YYYY-MM-DD') date_to  from dual union all
        select 2 id, to_date('2018-03-20','YYYY-MM-DD') date_from, to_date('2018-04-11','YYYY-MM-DD') date_to  from dual )
select
    *
from 
    table1
where
/*
        to_date('2018-03-01','YYYY-MM-DD') < date_to
    and to_date('2018-03-31','YYYY-MM-DD') > date_from

        to_date('2018-04-01','YYYY-MM-DD') < date_to
    and to_date('2018-04-30','YYYY-MM-DD') > date_from
*/
        to_date('2018-04-01','YYYY-MM-DD') < date_to
    and to_date('2018-04-03','YYYY-MM-DD') > date_from
;

谢谢大家的回复。我找到了答案

WHERE ((from_date BETWEEN {fromDate} AND {toDate} OR to_date BETWEEN {fromDate} AND {toDate} OR (from_date <= {fromDate} AND to_date >= {fromDate}))

如果使用CakePHP3：

->where([
        'OR' => [
            function($exp) use($fromDate,$toDate){                            
                return $exp->between('from_date',$fromDate,$toDate,'date');
            },
            function($exp) use($fromDate,$toDate){                            
                return $exp->between('to_date',$fromDate,$toDate,'date');
            }, 
            'AND' => [
                'from_date <=' => $fromDate,
                'to_date >=' => $fromDate
            ]
        ],
        'from_date is not' => null
    ]);

这取决于你想要的条件。您的记录中有一个日期范围，但也提供了一个条件的日期范围，该日期是包含的还是独占的？请提供完整的输入/输出示例。当然，你试过什么吗？@AxelH，我只想获得上述所有条件的记录2。事实上，我自己已经找到了答案。谢谢，顺便说一句。@a_horse_，没有名字，我正在使用mysql

with 
    table1 as 
      ( select 1 id, to_date('2017-05-15','YYYY-MM-DD') date_from, to_date('2017-06-12','YYYY-MM-DD') date_to  from dual union all
        select 2 id, to_date('2018-03-20','YYYY-MM-DD') date_from, to_date('2018-04-11','YYYY-MM-DD') date_to  from dual )
select
    *
from 
    table1
where
/*
        to_date('2018-03-01','YYYY-MM-DD') < date_to
    and to_date('2018-03-31','YYYY-MM-DD') > date_from

        to_date('2018-04-01','YYYY-MM-DD') < date_to
    and to_date('2018-04-30','YYYY-MM-DD') > date_from
*/
        to_date('2018-04-01','YYYY-MM-DD') < date_to
    and to_date('2018-04-03','YYYY-MM-DD') > date_from
;

WHERE ((from_date BETWEEN {fromDate} AND {toDate} OR to_date BETWEEN {fromDate} AND {toDate} OR (from_date <= {fromDate} AND to_date >= {fromDate}))

->where([
        'OR' => [
            function($exp) use($fromDate,$toDate){                            
                return $exp->between('from_date',$fromDate,$toDate,'date');
            },
            function($exp) use($fromDate,$toDate){                            
                return $exp->between('to_date',$fromDate,$toDate,'date');
            }, 
            'AND' => [
                'from_date <=' => $fromDate,
                'to_date >=' => $fromDate
            ]
        ],
        'from_date is not' => null
    ]);
