The following query:
SELECT * FROM `objects`
WHERE (date_field BETWEEN '2010-09-29 10:15:55' AND '2010-01-30 14:15:55')
returns nothing.
I should have more than enough data to for the query to work though. What am I doing wrong?
Your second date is before your first date (ie. you are querying between September 29 2010 and January 30 2010). Try reversing the order of the dates:
SELECT *
FROM `objects`
WHERE (date_field BETWEEN '2010-01-30 14:15:55' AND '2010-09-29 10:15:55')
Official Docs: https://dev.mysql.com/doc/refman/8.0/en/datetime.html
where clause should work the same on select or update statements.DATE() is a MySQL function that extracts only the date part of a date or date/time expression
SELECT * FROM table_name WHERE DATE(date_field) BETWEEN '2016-12-01' AND '2016-12-10';
As extension to the answer from @sabin and a hint if one wants to compare the date part only (without the time):
If the field to compare is from type datetime and only dates are specified for comparison, then these dates are internally converted to datetime values. This means that the following query
SELECT * FROM `objects` WHERE (date_time_field BETWEEN '2010-01-30' AND '2010-09-29')
will be converted to
SELECT * FROM `objects` WHERE (date_time_field BETWEEN '2010-01-30 00:00:00' AND '2010-09-29 00:00:00')
internally.
This in turn leads to a result that does not include the objects from 2010-09-29 with a time value greater than 00:00:00!
Thus, if all objects with date 2010-09-29 should be included too, the field to compare has to be converted to a date:
SELECT * FROM `objects` WHERE (DATE(date_time_field) BETWEEN '2010-01-30' AND '2010-09-29')
You can do it manually, by comparing with greater than or equal and less than or equal.
select * from table_name where created_at_column >= lower_date and created_at_column <= upper_date;
In our example, we need to retrieve data from a particular day to day. We will compare from the beginning of the day to the latest second in another day.
select * from table_name where created_at_column >= '2018-09-01 00:00:00' and created_at_column <= '2018-09-05 23:59:59';
Just Cast date_field as date
SELECT * FROM `objects`
WHERE (cast(date_field as date) BETWEEN '2010-09-29' AND
'2010-01-30' )
Might be a problem with date configuration on server side or on client side. I've found this to be a common problem on multiple databases when the host is configured in spanish, french or whatever... that could affect the format dd/mm/yyyy or mm/dd/yyyy.
To display post(s) between 2 specific dates (for example):
an occasion starts on (04-12) and ends on (04-14) without selecting a year in query to make it recurrent every year on the specified dates, So my goal is to display that occasion on startdate and hide it automatically on enddate as follow:
$stmt = $db->query(
"SELECT * FROM table
WHERE (CAST(CURDATE() AS date)
BETWEEN
CAST(table.date_start AS date)
AND
CAST(table.date_end AS date))
LIMIT 1"
);
Now, the occasion starts and disappear between these specified dates only, not after or before.
minandmaxvalues are considered to be in the range, to not process twice a date that is either theminandmaxvalue (edge case). For instance, the date2010-09-29 00:00:00will be between2010-09-28 00:00:00and2010-09-29 00:00:00, AND ALSO between2010-09-29 00:00:00and2010-09-30 00:00:00
