I am storing rows with MySQL using a date col. Everytime I insert a new row I use date=CURDATE() .
Is there anyway I can run a SELECT statement that selects all rows that were created within the last 24 hours?

Try this:
SELECT * FROM table WHERE date >= DATE_SUB(NOW(), INTERVAL 24 HOUR))
You can use the sub_date() function with interval to make a range of dates between now and 24 hours ago:
SELECT * FROM
table WHERE
date_field BETWEEN curdate() AND DATE_SUB(curdate(), INTERVAL 1 DAY);

I am attempting to find records in my DB that's end_date is within 24 hours of the current time.
Here is the query I am currently running
select *
FROM record r
WHERE NOW() BETWEEN r.end_date AND DATE_ADD(r.end_date, INTERVAL -1 DAY);
This doesn't bring back any of the records with an end_date within 24 hours, am I using the DATE_ADD function wrong?
I think this is what you need:
select *
FROM record r
where
r.end_date >= date_add(now(), INTERVAL -1 DAY)
I want to query from MySQL where posts will come only which is updated within last hour but not created in last hour.
Here is my MySQL query:
SELECT *
FROM
(SELECT *
FROM posts
WHERE (updated_at >= (NOW() - INTERVAL 30 MINUTE))) AS A
WHERE (created_at < DATE_SUB(NOW(), INTERVAL 60 MINUTE))
But this query doesn't give me right result.
I am attaching sample posts in CSV and adding result output from this query.
Sample: []
Query Output: []
I think you just need both conditions in a WHERE clause:
SELECT *
FROM posts
WHERE
updated_at >= DATE_SUB(NOW(), INTERVAL 1 HOUR) AND
created_at < DATE_SUB(NOW(), INTERVAL 1 HOUR);
Given a set of data with date_created stored like 2017-04-13 23:29:52, how would I construct an SQL query to select all items that were created within the last 3 hours?
I originally thought to do something like this:
SELECT
*,
MAX(date_created)
FROM items
GROUP BY date_created
but that would not be exactly what I want. I'm not sure how to go about this.
Use NOW() and INTERVAL in your WHERE clause
SELECT * FROM items WHERE date_created <= NOW() - INTERVAL 180 minute AND date_created >= NOW() - INTERVAL 210 minute
This one uses CURDATE, CURDATE and DATE_ADD:
SELECT *
FROM items
WHERE DATE(date_created) = CURDATE()
AND TIME(date_created) BETWEEN CURTIME() AND DATE_ADD(CURTIME(), INTERVAL -3 HOUR)
select * from items where
extract(hours from age(current_timestamp, date_created))>=3;
Extract keyword would extract hours difference from current timestamp and return only that is greater than or equal to 3.
I'm having trouble coming up with this solution logically. I have an accounts table with a datetime trial_expiration_date column. I'd like to return all accounts that have been expired for at least two weeks but no more than one month using this column. How can I achieve this?
Something like this should work. Just select all records where the expiration date is between two weeks ago and one month ago.
select *
from accounts
where trial_expiration_date between DATE_SUB(curdate(), INTERVAL 1 MONTH)
and DATE_SUB(curdate(), INTERVAL 2 WEEK)
How about this..
select *
from TABLE
where trial_expiration_date between dateadd(day,-14,getdate()) and getdate()
You can do
select *
from t
where
datediff(date_add(trial_expiration_date, interval 2 week), now()) < 0
and
datediff(date_add(trial_expiration_date, interval 1 month), now()) > 0
It only calculate the date parts only and does not consider time.
I would like to rows that have only been entered in the last 1 day.
I have a date column which stores YYYY-MM-DD, and I allow the user to send a date that they want to look at in this format yyymmdd how can I use this data to limit it to the previous day only?
I would imagine it is something to do with the BETWEEN keyword but I cant figure it out.
SELECT * from TABLE_NAME WHERE ROW_DATE BETWEEN '2011-03-20' AND '2011-03-21'
This query:
SELECT *
FROM mytable
WHERE mydate >= STR_TO_DATE('110321', '%y%m%d') - INTERVAL 1 DAY
AND mydate < STR_TO_DATE('110321', '%y%m%d')
will return all records for Mar 20, 2011
From the MySQL manual (here):
SELECT something FROM tbl_name WHERE DATE_SUB(CURDATE(), INTERVAL 1 DAY) <= date_col;
SELECT * FROM YourTable WHERE date_column = DATE_ADD(CURDATE(), INTERVAL -1 DAY)
This returns all rows for today and yesterday.
