How to check a dates of a date range lies in between two dates in mysql query

问题

I have a date range like

date from=2011-10-14 & date to=2011-10-20

if I have another date ranges

like

- 2011-10-11 - 2011-10-15
- 2011-10-11 - 2011-10-21
- 2011-10-15 - 2011-10-21
- 2011-10-15 - 2011-10-19
- 2011-10-21 - 2011-10-26

I want sql query which shows only the date range whose dates lies in between above (2011-10-14 & date to=2011-10-20) date range.

Here only 2011-10-21 - 2011-10-26 does not lies in date from=2011-10-14 & date to=2011-10-20

Result must show

- 2011-10-11 - 2011-10-15
- 2011-10-11 - 2011-10-21
- 2011-10-15 - 2011-10-21
- 2011-10-15 - 2011-10-19

these dates

Hope you understand what I am asking.

回答1:

date_from < '2011-10-20' AND date_to > '2011-10-14'

回答2:

SELECT * FROM datetable where mydate BETWEEN '2011-10-14' AND '2011-10 20';

回答3:

WHERE date_from >= '2011-10-14' AND date_to <= '2011-10-20'?

But this will only work if you have your column's data type set to DATE or DATETIME

You can go and search on the Internet :-)

The first links you will come across is this: http://www.c-sharpcorner.com/Blogs/692/

Hope the above link helps in resolving your query.

Or, you could give something like this:

SELECT * FROM myTBL WHERE myReqDate NOT BETWEEN '2011-10-14' AND '2011-10-20'
