Sql 在两列中选择两个日期之间的记录

如何在两列中选择两个日期之间的记录

Select * From MyTable Where 2009-09-25 is between ColumnDateFrom to ColumnDateTo

我有一个日期2009-09-25，我喜欢选择时间范围列DateFrom到ColumnDateTo中的记录

样品

记录1 ColumnDateFrom=2009-08-01和ColumnDateTo=2009-10-01

记录2 ColumnDateFrom=2010-08-01和ColumnDateTo=2010-10-01

---

如果我的输入日期是2009-09-28；然后我得到记录1

如果我理解正确，请尝试以下操作：

select * 
from MyTable 
where ColumnDateFrom <= '2009-09-25' 
    and ColumnDateTo >= '2009-09-25'

SELECT
    *
    FROM MyTable 
    WHERE ColumnDateFrom <= '2009-09-25' AND ColumnDateTo >= '2009-09-25'

试试这个：

SELECT * FROM MyTable WHERE '2009-09-25' BETWEEN ColumnDateFrom AND ColumnDateTo

T-SQL之间的标准应起作用

SELECT * FROM MyTable WHERE @MYDATE BETWEEN ColumnDateFrom AND ColumnDateFrom

只需拆下它就可以了

Select * From MyTable 
Where '2009-09-25' Between ColumnDateFrom to ColumnDateTo

记住，如果列值中有日期和时间，请考虑时间PATIOMN。 假设DateOnly是从datetime列中提取时间的函数

Select * From MyTable 
Where '2009-09-25' Between DateOnly(ColumnDateFrom) 
                        To DateOnly(ColumnDateTo)

这里是ms access vba的示例

"[LearningBegin]<= " & Format(eFilterBegin.Value, "\#mm\/dd\/yyyy\#") + " and [LearningEnd]>=" + Format(eFilterEnd.Value, "\#mm\/dd\/yyyy\#") + _
" or [LearningBegin]>= " & Format(eFilterBegin.Value, "\#mm\/dd\/yyyy\#") + " and [LearningEnd]<=" + Format(eFilterEnd.Value, "\#mm\/dd\/yyyy\#") + _
" or [LearningBegin] between " & Format(eFilterBegin.Value, "\#mm\/dd\/yyyy\#") + " and " + Format(eFilterEnd.Value, "\#mm\/dd\/yyyy\#") + " and [LearningEnd]<=" + Format(eFilterEnd.Value, "\#mm\/dd\/yyyy\#") + _

这是哪个特定的数据库引擎？您将如何将日期作为嵌入式文本（即作为SQL的一部分或作为参数）传递给SQL？您使用什么客户机框架与数据库通信？基本上你的问题是什么？SQL语法？如何用C或php或其他语言编写？还是怎样因为，就想法而言，你是对的，除了写日期的语法是错的，但我需要知道你用哪个数据库引擎来告诉你什么是对的。很好，但我更喜欢。。。从MyTable中选择*，其中ColumnDateFrom和ColumnDateTo之间的“2009-09-25”非常感谢您的快速响应…非常好！我现在做完了，可以回家了。。。祝大家周末愉快！我从不使用BETWEEN，我发现它更容易阅读>=，>，这个对日期列的函数调用将阻止任何索引的使用，不是吗？
