Fetch rows with DATE - mysql

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);

Find a record between two dates MySQL

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)

Find records from MySQL which is updated within last hour but not created within last hour

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);

SQL Query by created 3 hours ago

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.

Date ranges in SQL

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.

Return rows between two dates in MySQL

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.
