2013-01-15 23:44:02
i have use strtotime('-1 day') but it returns local system time.i want to get one day old record and do some stuff in condition..
Thanx in advance..
where date(date_column) = DATE_sub(NOW(), INTERVAL 1 DAY);
use DATE_ADD
SELECT *
FROM tablename
WHERE DATE(dateCol) = DATE_ADD(CURDATE(),INTERVAL -1 DAY)
DATE_ADD()
SELECT * from table WHERE datefield < DATE_SUB(NOW(), INTERVAL 1 DAY)
You will be archiving this with sql query.
SELECT * FROM tablename WHERE DATE(datefield)=DATE_ADD(CURDATE(),INTERVAL 1 DAY)
CURDATE() will return the current Mysql Server time.
You can use this function DATE_SUB(date,INTERVAL expr type)

Assume we have the following "Orders" table:
Columns: OrderId, ProductName, OrderDate
Values: 1, Jarlsberg Cheese, 2008-11-11 13:23:44.657
Now we want to subtract 5 days from the "OrderDate" date.
We use the following SELECT statement:
SELECT OrderId,DATE_SUB(OrderDate,INTERVAL 5 DAY) AS SubtractDate
FROM Orders
$yesterday = strtotime('Y-m-d h:i:s','yesterday');
SELECT * FROM tablename WHERE datefield = '$yesterday'

I Have An table As Follow
I need Data Only From Last Hour. Following query i tried using Reference.
SELECT * FROM `user_otp`
WHERE `date` = '$todate'
AND datetime > DATEADD(HOUR, -1, GETDATE())
I Dont Know This But I tried Using This Refferance
But It Not Work For Me .
So Any Help Would be useful.
DATEADD and GETDATE() exist in SQL Server.
In MySQL, your conditions should be:
WHERE `datetime` > DATE_ADD(NOW(), INTERVAL -1 HOUR)
While date = '$todate' condition is redundant and should be removed.
Here's a documentation in MySQL DateTime.
Use DATE_SUB and NOW() functions in query
SELECT count(*) as lasthour_count
FROM user_otp
WHERE datetime >= DATE_SUB(NOW(),INTERVAL 1 HOUR);
Hi you can use DATE_SUB function for fetch last one hour data. I edited your code below -
SELECT * FROM `user_otp`
WHERE `date` = '$todate'
AND datetime >= DATE_SUB(NOW(),INTERVAL 1 HOUR);
datetime>=DATE_ADD(NOW(), INTERVAL -1 HOUR);
datetime>= DATE_sub(NOW(), INTERVAL 1 HOUR);
These are the two options you can use
I am querying records from the last calendar month. As it is February, it should return all the records that were added on January this year.
My Query:
`SELECT * FROM table_name WHERE date >=
DATE_ADD(LAST_DAY(DATE_SUB(NOW(), INTERVAL 2 MONTH)), INTERVAL 1
DAY) AND date <= DATE_ADD(LAST_DAY(DATE_SUB(NOW(), INTERVAL 1
MONTH)), INTERVAL 0 DAY) AND campaign = '$campaign' ORDER BY date
ASC`
It returns some records but skips the first 9 days. It starts showing records from 10th of the previous month. What am I missing here?
check your date field type and make sure you have not mistaken it with varchar.
SELECT * FROM table_name WHERE
(MONTH(date) = (MONTH(NOW()) - 1) AND YEAR(date) = YEAR(NOW()))
OR
(MONTH(date) = 12 AND MONTH(NOW())=1 AND YEAR(date) = (YEAR(NOW()) - 1) AND campaign = '$campaign' ORDER BY date
ASC`
Try To Get Data in step by step like,
First, you should try below query.
SELECT Date, DATE_ADD(LAST_DAY(DATE_SUB(NOW(), INTERVAL 2 MONTH)), INTERVAL 1 DAY) AS StartDate, DATE_ADD(LAST_DAY(DATE_SUB(NOW(), INTERVAL 1 MONTH)), INTERVAL 0 DAY) AS EndDate FROM MyTable
Second, If First Step give right date then get your data by directly writing your date rather than DATE_ADD function in where clause.
Third, If These will Give you write DATA then try to fetch data using DATE_ADD function.
Replay If you will get solution.
SELECT * FROM table_name WHERE date between DATE_SUB(DATE_SUB(CURRENT_DATE,INTERVAL DAYOFMONTH(CURRENT_DATE)-1 DAY),INTERVAL 1 MONTH) AND DATE_SUB(DATE_SUB(CURRENT_DATE,INTERVAL DAYOFMONTH(CURRENT_DATE)-1 DAY),INTERVAL 1 DAY) AND campaign = '$campaign' ORDER BY date ASC
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
I need to select from a table all rows that have date_added between CURDATE() and 6 weeks ago.
Help please.
SELECT *
FROM mytable
WHERE date_added BETWEEN CURDATE() - INTERVAL 6 WEEK AND CURDATE()
SELECT *
FROM a_table
WHERE date_added BETWEEN DATE_SUB(CURDATE(), INTERVAL 6 WEEK) AND CURDATE()
SELECT * FROM table_name WHERE TO_DAYS(NOW()) - TO_DAYS(date_added) <= 42
SELECT * FROM table_name WHERE DATEDIFF(NOW(),date_added)<=42
if you use dates in one year
select date_format(date, '%u') from tab
where (date_format(date, '%u')-date_format(now(), '%u'))>6
if you use dates with different years
you don't have to use dates with another year.
you can use
select
date_format(date, '%u') from tab
where (date_format(date, '%u')-date_format(now(), '%u'))>6
and
date_format(date, '%u') from tab
where (date_format(date, '%Y')-date_format(now(), '%Y'))=0
you can optimize query with join if you want. I think you know how to do it
I have a list of unix timestamps in a database, and I wanting to select the ones that are from today.
i.e If today is Tueday, I want to get all the timestamps that were made today? Is it possible? Is there such a things as strtotime("Today")?
Any help would be great
you can use mktime() to generate the timestamp for the start of the day and then find the database entries with a timestamp greater than that.
$start = strtotime(date('Y-m-d 00:00:00')); // Current date, at midnight
$end = strtotime(date('Y-m-d 23:59:59')); // Current date, at 11:59:59 PM
then, you can just select where the timestamp is between the above 2 timestamps:
"SELECT FROM `foo` WHERE `timestamp` BETWEEN '{$start}' and '{$end}'"
You can convert the unix timestamps to sql dates in the SQL using FROM_UNIXTIME(), then compare those to NOW()
SELECT * FROM `tablename` WHERE DATE(FROM_UNIXTIME(`dateFld`)) = DATE(NOW());
Check if DAY(NOW()) and MONTH(NOW()) and YEAR(NOW()) is equal to appropriate value of DAY(timestamp) and MONTH(timestamp) and YEAR(timestamp).
select timestamp from table where DAY(NOW()) = DAY(timestamp) AND MONTH(NOW()) = MONTH(timestamp) AND YEAR(NOW()) = YEAR(timestamp)
If you're using mysql:
SELECT * FROM table WHERE DATE(NOW()) = DATE(FROM_UNIXTIME(timestampcol))
FROM_UNIXTIME(somefield) can be compared to CURDATE() assuming you're using MySQL
SELECT * FROM mytable WHERE FROM_UNIXTIME(datefield,'%Y-%m-%d') = CURDATE();
ETA:
Okay, I was assailed by doubt when this answer was marked down. So I went and did a couple of tests. Given MySQL it definitely works. So why the downmod?
Consider this test which outputs 2 identical fields for every row in a table:
SELECT FROM_UNIXTIME(UNIX_TIMESTAMP(CURDATE()),'%Y-%m-%d') a , CURDATE() b
FROM tablewithsomerows
WHERE FROM_UNIXTIME(UNIX_TIMESTAMP(CURDATE()),'%Y-%m-%d') = CURDATE();
