I'm sorry if this sounds like a very basic question but for some reason, today I'm really having trouble getting my head round this. I have a database table with a date_added column in the format of 2014-09-30 20:39:17 and I have a web page with filter options for users. Basically I want to use variables to select different date ranges like so:
SELECT * FROM table WHERE date_added = /* EVERYTHING POSTED TODAY */
SELECT * FROM table WHERE date_added = /* EVERYTHING POSTED WITHIN LAST 7 DAYS */
SELECT * FROM table WHERE date_added = /* EVERYTHING POSTED WITHIN LAST 30 DAYS */
What would I need to put in to get those variables to work?
You can use CURDATE() and very simple INTERVAL arithmetic.
In the following examples assume that query was executed at 2014-10-21 22:25:28:
SELECT * FROM table WHERE date_added >= CURDATE()
-- >= 2014-10-21 00:00:00
SELECT * FROM table WHERE date_added >= NOW() - INTERVAL 24 HOUR
-- >= 2014-10-20 22:25:28
SELECT * FROM table WHERE date_added >= CURDATE() - INTERVAL 7 DAY
-- >= 2014-10-14
SELECT * FROM table WHERE date_added >= CURDATE() - INTERVAL 30 DAY
-- >= 2014-09-21

I use MariaDB and have a table where each row has a date and a score.
I want to first show the rows where the date is 3 days old or newer, sorted by the score - then show the rest (more than 3 days old) sorted by date.
Since my date is stored in unix time, it's fairly easy to have php calculate 3 days from before now and use that as my $scoreTimeLimit variable in the below:
Here are my two queries:
SELECT * FROM myTable WHERE myDate > $scoreTimeLimit ORDER BY myPopularityScore DESC
SELECT * FROM myTable WHERE myDate < $scoreTimeLimit ORDER BY myDate DESC
However, I would VERY much like to have only 1 query instead of two. Can it be done...?
This is a job for UNION.
SELECT * FROM (
SELECT 0 ord1, NOW() as ord2, *
FROM myTable WHERE myDate > NOW() - INTERVAL 3 DAY
UNION ALL
SELECT 1 ord1, myDate as ord2, *
FROM myTable WHERE myDate <= NOW() - INTERVAL 3 DAY
) a
ORDER BY ord1, ord2 DESC, myPopularityScore
The inner query gives you a single result set with a couple of extra columns added on to help you manage your sorting.
I have table "bookings" in mysql and i want to fetch those record whose "bookingtime"(data type is "Datetime") more than 40 minutes ( according to IST)
My query not working with IST,
Here is my table "booking"
id name bookingtime
1 ayhd 2020-01-09 15:23:33
2 dhdye 2020-01-09 14:53:38
3 juey 2020-01-09 11:13:53
I tried with following query but not showing any result,Where i am wrong ?
SELECT * FROM booking
WHERE bookingtime < (NOW() - INTERVAL 40 MINUTE)
try this query , it will get records between now and 40 minutes ago
SELECT * FROM `booking` WHERE `bookingtime` >= (NOW() - INTERVAL 40 MINUTE) AND `bookingtime` < NOW()
I am trying to retrieve data for the passed 24 hours but I am getting nothing, but when I check on the table column (days) directly in db, I can find them. Here is my query:
select * from mytable
where
days between concat(date(date_sub(now(), interval 1 day))
between requires 2 arguments that specify the range:
select * from mytable
where days between date_sub(now(), interval 1 day) and now();
Or simply
select * from mytable
where days > date_sub(now(), interval 1 day);
You can use
select * from mytable where days > date_sub(CURDATE(),INTERVAL 1 DAY);
I have a mysql table with the following fields
Name | Email | Date | Status
I want to extract the records where date range is between 30 days
Assume today is 2014/12/9
ie. date values are
2014/11/25
2014/12/2
2014/12/1
2014/10/25
2014/11/9
I need the o/p as (the number of days should be with in 30 days from the db date to today date)
2014/11/25
2014/12/2
2014/12/1
2014/11/9
I want to extract records those have the interval of less than 30 days from the date in the db.
Yes. I want to fetch the record between 2 days. For this I used this query
SELECT * FROM tbl_jobboard WHERE dtDate <= ( dtDate +30 )
But it is not working.
How to write the select query?
USE DATE_SUB like this:
SELECT * FROM table1
WHERE `date` BETWEEN DATE_SUB(CURDATE(),INTERVAL 30 DAY) AND CURDATE()
Working Fiddle Demo: http://sqlfiddle.com/#!2/6344f2/1
use following query
select * from table_Name t where t.date<=now() and t.date>=DATE_SUB(now(),
INTERVAL 31 DAY)
I am in problem in mysql database data retrieving. I have to get latest data inserted within a week or latest 7 days. I just know get data of specific date, but no within a span of days.
Please anyone help me. I am new in mysql.
You are looking for INTERVAL. For example, this will find all users whose created_time is in last 7 days and you have field created_time to tracked date of creation of record
SELECT * from users where created_time > (NOW()-INTERVAL 7 DAY)
You can do it using below query.
SELECT *
FROM `table`
WHERE `date` BETWEEN DATE_SUB(CURDATE(), INTERVAL 7 DAY) AND
CURDATE()
OR
SELECT * FROM `table` WHERE `date` >= DATE_SUB(CURDATE(), INTERVAL 7 DAY)
OR
SELECT * FROM table WHERE DATEDIFF(NOW(),dateField) < 7
we can use DATE_SUB Mysql default function
select * from yourtable where date_of_insertion >= DATE_SUB(NOW(),INTERVAL 7 DAY)
<?php
$date = date("your_date_format", strtotime(- 7 days));
$result = mysqli_query($link, "SELECT * FROM table WHERE `date` > '$date'");
?>
Simple as that.
try :
select * from tablename where add_time >= now() - interval 7 day
