I'm trying to build a query where it will return all rows from today's date, but only up to this point in time of the day.
E.G.
If it's 12.30pm, I'd like it to return all rows with the date from 00:00 to 12:30 on today's date, but nothing after 12:30, or whatever time is when the scrips is run
DATE(expression) removes the time and NOW() includes the current time:
SELECT * FROM tbl WHERE iDate > DATE(NOW()) and iDate < NOW()
have you tried:
SELECT * FROM table WHERE date < TODAY && date > DAYBEFORE
something like this should work fine for timestamp saved dates. Not sure about DATE formated values
You can specify a starting timestamp and an ending timestamp:
where created >= timestamp_start && created < timestamp_end
Note that my answer assumes you're using some server side programming language to run these sql queries, and thus you would be passing a variable into timestamp_start and timestamp_end. time format: use Unix Timestamp

I am trying to select everything from my table with today's date. But I found that that date column is in unix time stamp. So, how do I select everything with today's date? or for example only yesterday's ? If it was normal date instead of unix time it would be easy, but... here is what I have put for my query so far..
$ann_renewal_query = "SELECT * FROM annual_renewal WHERE due_date '%$today%' order BY due_date ASC";
You just need to convert the values to the unix timestamp version. The best way is to convert the current time to Unix timestamp:
where due_date >= UNIX_TIMESTAMP(curdate()) and
due_date < UNIX_TIMESTAMP(date_add(curdate(), interval 1 day)
This version of the query allows it to take advantage of an index on due_date.
I'm wondering what would be the easiest way in MySQL to check if given date is in range regardless of the year.
In database table I have two DATE fields: start and finish stored in YYYY-mm-dd
if start = 2013-11-01 and finish = 2014-03-01 anything between 1st of November and 1st of March of any year should be accepted.
Valid dates:
2020-01-01 1980-02-28
Invalid dates:
2013-10-30 1968-07-30
There are almost certainly cleaner ways of doing it, however this should work:
((DAYOFYEAR(finish_date) > DAYOFYEAR(start_date)
AND (DAYOFYEAR(#date) >= DAYOFYEAR(start_date)
AND DAYOFYEAR(#date) <= DAYOFYEAR(finish_date)))
OR (DAYOFYEAR(finish_date) <= DAYOFYEAR(start_date)
AND (DAYOFYEAR(#date) >= DAYOFYEAR(start_date)
OR DAYOFYEAR(#date) <= DAYOFYEAR(finish_date))))
For a start date in Oct 2012 and end date in Nov 2020 this will return all dates in the Oct-Nov range. If in fact would want it to return all Dates when the range is greater than a year (and hence covers all dates of the year) you could add:
OR DATEDIFF(Day, start_date, finish_date) > 356
before the final bracket.
use DAYOFYEAR:
When the Start Date is earlier in the year than the Finished Date:
the tested Date should lye between Start Date and Finish Date (or on Start or Finish)
When the Finished Date is earlier in the year than the Start Date:
the tested Date should lye outside the Start Date and Finish Date (or on Start or Finish)
You can use some date extract function and then check your condition..
for example.
SELECT EXTRACT(MONTH FROM TIMESTAMP '2013-11-01 20:38:40');
this will give ouput start month as 11
SELECT EXTRACT(MONTH FROM TIMESTAMP '2014-03-01 20:38:40');
this will give ouput end month as 3
now you can check the condition from above two result..
SELECT * FROM tableWithDates t WHERE month(t.start) >= 11 AND month(t.finish) < 3
if you want the first of march it will go like this:
SELECT * FROM tableWithDates t WHERE month(t.start) >= 11 AND (month(t.finish) < 3 OR month(finish) <= 3 AND day(finish)<=1)
Depending on the size of the data you will run this at. You can get into performance problems, as MySQL can't use indexes of calculated columns.
If you run into this i suggest spitting the month AND/OR day into separate columns.
Edit:
Given an one parameter input as '2008-02-29'
SELECT * FROM tableWithDates t
WHERE
month(t.start) >= month('2008-02-29') AND day(t.start) >= day('2008-02-29')
AND month(t.finish) <= month('2008-02-29') AND day(t.finish) <= day('2008-02-29')
I am trying to select records from a database only if they match today's date. The format for the date in the database is 2012-06-20 9:30:00 I am using the statement SELECT id FROMnewsreportsWHERE DATE(newsdate) = CURDATE() but it doesn't not return any records for today?

DATE_FORMAT(NOW(),'%Y-%m-%d') = FORMAT_DATE(NOW(newsdate), '%Y-%m-%d')
Or better:
DATE(newsdate) = DATE(NOW())
The best way is to store the additional column with 2001-09-11 date format and compare this one
Example, thanks to #Conrad Frix
It looks like the curdate function is going to give you something different than the date format you've got in the database.
Take a look at the docs here
MySQL Date and Time Functions
It's supposed to return a date in this format:
2008-11-11
So, you could either search for a date range between curdate() and curdate() + INTERVAL 1 DAY (untested), or store the dates in the curdate() format.
I need to pull a variable amount of days of data from a MySQL database that stores the date as a UNIX timestamp in an int column.
For example, if I need the last 5 days of data, what would my query be?
(All queries would start from current date and would go back x amount of days).
Timestamp is considered one of the Date and Time types and therefore any of the Date Time Functions can be used on it.
SELECT * FROM your_table
WHERE Ftimestamp_column > UNIX_TIMESTAMP(DATE_SUB(NOW(), INTERVAL 5 DAY));
I've never tried it but there's a MySQL function to convert unix timestamps into MySQL dates and then you can use DATE_SUB() or whatever. http://dev.mysql.com/doc/refman/5.5/en/date-and-time-functions.html#function_from-unixtime
I am writing a cron job that will need to pull out the current days records. In my table I have a column called modify_date which is a unix time stamp, in format of 1/29/2011 9:59:47 AM
What would be the sql for the current date so it chooses the date part only and give current dats results accordingly.
thanks
SELECT * FROM table1 WHERE DATE(modify_date) = CURDATE();
you can have a check
WHERE data > '1/29/2011 00:00:01' and date < '1/29/2011 23:59:59'
