I have saved the dates of a user's registration as a datetime, so that's for instance 2011-12-06 10:45:36. I have run this query and I expected this item - 2011-12-06 10:45:36 - will be selected:
SELECT `users`.* FROM `users` WHERE created_at >= '2011-12-01' AND
created_at <= '2011-12-06'
But is not. Exist any elegant way, how to select this item? As a first idea that I got was like 2011-12-06 + 1
, but this doesn't looks very nice.
Searching for created_at <= '2011-12-06'
will search for any records that where created at or before midnight on 2011-12-06
. You want to search for created_at < '2011-12-07'
.
Another alternative is to use DATE()
function on the left hand operand as shown below
SELECT users.* FROM users WHERE DATE(created_at) BETWEEN '2011-12-01' AND '2011-12-06'
You can use MySQL DATE
function like below
For instance, if you want results between 2017-09-05 till 2017-09-09
SELECT DATE(timestamp_field) as date FROM stocks_annc WHERE DATE(timestamp_field) >= '2017-09-05' AND DATE(timestamp_field) <= '2017-09-09'
Make sure to wrap the dates within single quotation ''
Hope this helps.
Have you tried before and after rather than >= and <=? Also, is this a date or a timestamp?
SELECT users.* FROM users WHERE created_at BETWEEN '2011-12-01' AND '2011-12-07';
You need to use '2011-12-07' as the end point as a date without a time default to time 00:00:00.
So what you have actually written is interpreted as:
SELECT users.*
FROM users
WHERE created_at >= '2011-12-01 00:00:00'
AND created_at <= '2011-12-06 00:00:00'
And your time stamp is: 2011-12-06 10:45:36 which is not between those points.
Change this too:
SELECT users.*
FROM users
WHERE created_at >= '2011-12-01' -- Implied 00:00:00
AND created_at < '2011-12-07' -- Implied 00:00:00 and smaller than
-- thus any time on 06
Maybe use in between better. It worked for me to get range then filter it
