How to select a php date() format in SQL - php

I have an SQL table with a field "time_created" in the form "Wed, 19 Aug 2015 03:58:00 -0600".
I need to check this field against today and perform a where statement according to it, as in
SELECT * FROM table WHERE UNIX_TIMESTAMP() - UNIX_TIMESTAMP(time_created) >= 3600*24*30
to select records where time_created is older then a month.
Problem is UNIX_TIMESTAMP doesn't understand formats as "Wed, 19 Aug 2015 03:58:00 -0600". Any other way?


Try:
SELECT *
FROM table
WHERE DATE(NOW()) > DATE_SUB(STR_TO_DATE(time_created, '%a, %e %b %Y %T'), INTERVAL 1 MONTH)
This will find all records where the current date (DATE(NOW())) is bigger than time_created subtract ` month.

select varchar as date in mySQL

I have a date column in the format
25 Mar 2017 07:19 pm
I want to select date in the format dd/mm/yyyy
I have tried: cast(date as DATE), STR_TO_DATE(date, '%d/%m/%Y') but everything returns null
any help will be appreciated.

Use
select str_to_date('25 Mar 2017 07:19 pm', '%d %M %Y')
The format specified has to match the input pattern. As the month name is included, use %M.

You can parse the date using following format:
SELECT STR_TO_DATE('25 Mar 2017 07:19 pm', '%d %M %Y %h:%i %p');
Here's the SQL Fiddle.

Get last 24 hours data from SQL

Hi all i want to select from my table all records from last 24h , 7days , 14 days ....( my sql timespan format is date("l, M d Y, h:i:s A")) so when i try to receive the data from last 24h is not working for me any help plz
exemple
if i get all date from
$result = mysql_query("SELECT * FROM stats");
result is Day,Date,time Count
Saturday, Feb 27 2016, 02:28:59 PM 27191 Saturday, Feb 27 2016, 03:28:05 PM 28659 Saturday, Feb 27 2016, 04:27:26 PM 30138
so i try like that and not working any help plz
$result = mysql_query("SELECT * FROM stats WHERE timespan >= now() - INTERVAL 1 DAY");

SELECT * FROM stats WHERE STR_TO_DATE(timespan,"%W, %b %d %Y, %h:%i:%s %p") >= date_sub(now(), INTERVAL 1 DAY)
STR_TO_DATE will convert your the string into date format (Y-m-d H:i:s) and then you can compare it with the date returned by now()

This should work. Make sure "timespan" exists and that it is a date. According to your example you should test on the "date" field.

TIME in mysql minus 1 hour

i am selecting the time from a DATETIME field in mysql as a valid RFC2822 dateformat.
But i want mysql to select the date but directly subtract 1 hour of the time.
This is my script now:
$sql_select_bezig = "SELECT
DATE_FORMAT(verzonden_op,'%a, %d %b %Y %T') AS rfc_date,
message_id
FROM
email_tracking
WHERE
DATE(verzonden_op) > DATE_SUB(now(), INTERVAL 2 WEEK)";
Now it is only selecting the date and displays it like Sun, 14 Sep 2014 20:13:33 +0100.
That's ok, but how do i subtract 1 hour?

Select DATE_FORMAT(Date_SUB(date, 2, HOURS)...) AS ... from ...

In a SQL statement, we can substitute an expression for a column name.
Anywhere column name verzonden_op appears in your statement, you can replace that with the expression that VMai suggested...
verzonden_op - INTERVAL 1 HOUR

Use Unix timestamp as a condition in mysql

I have a table that is similar to the one below. As you can see, I have stored the dates as Unix timestamps. My goal is to only return the results which are for the upcoming dates, not the ones which are in past. How can I achieve this?
id | date
1 1331506800 //Mar 12 2012
2 1366149600 //Apr 17 2013
3 1413928800 //Oct 22 2014
4 1436652000 //Jul 12 2015
Desire result:
id | date
1 1413928800 //Oct 22 2014
2 1436652000 //Jul 12 2015

SELECT *
FROM table
WHERE date > UNIX_TIMESTAMP()

$h->query("SELECT * FROM thetable WHERE date > " . time());
This will also work in other databases than MySQL which do not have UNIX_TIMESTAMP() function.

Try this::
Select * from table
where DATEDIFF(STR_TO_DATE(dateColumn, '%e %b %Y %k:%i')),now())>0

Query returns Date (YYYY-MM-DD) and want to display as Friday, Oct 15

I have a query that is grabbing the Date of a given post. I'm displaying this information in a chart that has the date and number of posts for that day. How can I display "Friday, Oct 15" instead of 2010-10-15??
Query:
$oct_week = mysql_query("SELECT COUNT(*), DATE(`dPostDateTime`) AS `day` FROM `tblQA` WHERE dPostDateTime >= '2010-10-01' AND dPostDateTime <= '2010-10-31' GROUP BY `day`");

DATE_FORMAT(DATE(`dPostDateTime`), '%W, %b, %e')
