I insert a date in PHP created like that :
$myDate = date('Y-m-d H:i:s');
It works perfectly. If I change the format like that :
$myDate = date('d-m-Y H:i:s');
The value inserted is 0000-00-00...
It exsists a way to insert a date in French format ?
MYSQL only allows yyyy-mm-dd format for storage so it is impossible to store dates in the French format.
You can change the field type to be a char or any other string type if you want to store the dates in any format of your choice but you won't be able to perform MYSQL date functions, during queries, on the field.
It is better to follow the standard format and have a script convert the date to whatever format you want when you want to display the date to users.

MySQL table has 2 columns - startdate and enddate
They hold dates in this format: 22-01-2016
When I was prototyping, I used MediumText.
Now, I want to switch to Date format. The default date format in PHPMyAdmin is YYYY-MM-DD
If I switch the columns to Date, my data turns into 0000-00-00.
Using PHP or MySQL, how do I reformat my data prior to going back into PHPMyAdmin to switch the columns to Date format?
You can use string to date function to update columns data before changing its structure
UPDATE table SET dateColumn = STR_TO_DATE(dateColumn, '%d-%m-%Y');
It will convert DD-MM-YYYY formatted dates to YYYY-MM-DD. After that you can just change structure of column to DATE
The easiest and most reliable way would be to split up the dates and rearrange them the other way round:
$parts = explode('-', $olddate);
$newdate = sprintf('%04d-%02d-%02d', $parts[2], $parts[1], $parts[0]);
I need to insert the current date in the following format into a TIMESTAMP column in a MySQL db: d-m-Y
As of now I am using SQL NOW(), which returns the date as Y-m-d. Because I am using AJAX to display the data I cannot format the returned result using $date_returned->format(d-m-Y). Therefore I need to insert the date in the format that I will display on my AJAX call.
I tried to insert the date using the following functions:
1) date('d-m-Y');
2) (new \DateTime())->format('Y-m-d');
I understand these two functions do pretty much the same thing but I was not sure what else I should try.
MySQL threw the following error for both dates:
Error : (1292) Incorrect datetime value: '-2014' for column 'msg_date' at row 1
I am guessing this should be an easy fix but I can't figure out what is wrong.
I tried both TIMESTAMP and DATETIME on MySQL's end but neither worked. (I need it to be TIMESTAMP though).
Any suggestion is welcome!
$newdate= date('Y-m-d', strtotime('10-09-2015'));
or if you want current time just use
$now = date('Y-m-d');
If your msg_date column's structure is DATETIME or TIMESTAMP, the date format should be:
YYYY-MM-DD HH:MM:SS
which can be formatted through PHP like this:
$date = date("Y-m-d H:i:s");
Or if you already have a date, and you want it to convert to that format, we can use strtotime():
$date = date("Y-m-d H:i:s", strtotime($date));
For more date format, check this link.
The MySQL error message indicated that you had the date format the wrong way around.
Year must go first, then month, then day, as in:
date('Y-m-d') // right
In your first example, you have
date('d-m-Y') // wrong
In one of your examples above, you have it right, but you say you got the same response, so I assume that was not what you actually tried.
Another thing to note is that a MySQL TIMESTAMP column stores both a date and time. It's valid to give MySQL just a date (MySQL will just leave the time at zero), but if you have no need to store a time, you may as well make the column DATE instead of TIMESTAMP.
If you want to display your dates as d-m-Y then by all means do so, but they need to be sent to MySQL as Y-m-d.
I have issue with this date m/d/y for example 01/09/15 but when i insert that in my table of field name date and declared date i adde to me 2001/09/15 how can i save this format 01/09/15 in field database of my table
You can't change the format of mysql dates. You could save your date as a varchar but you can't use any manipulation.
You can save it as a mysql date or a time int, and then cast it to the format that you want, using date function.
You can read more about this in this post:
Change date format (in DB or output) to dd/mm/yyyy - PHP MySQL
I hope this will be useful.
Hope somebody can advise on the following:
I have created a table into my database which has a coloumn with datatype defined as DATE. The normal MySQL date order is YYYY-MM-DD, however I need to enter it in format DD-MM-YYYY.
I am using php to insert data into my table, and I was wondering at what point should I convert the date format.
To summerize, I am asking the following:
Is it possible to insert into MySQL database where field is formatted as DATE, a date in format DD-MM-YYYY instead in format YYYY-MM-DD?
If not possible, can I convert a value posted from PHP in format DD-MM-YYYY into the format YYYY-MM-DD using the MySQL syntax or I should use PHP to post the value in YYYY-MM-DD format?
Thank you in advance
You would use STR_TO_DATE in your INSERT to convert the date to the ANSI standard date format.
INSERT INTO `table` (`date`) VALUES (STR_TO_DATE('01-05-2013','%d-%m-%Y'));
You can then use DATE_FORMAT to convert the ANSI standard date to the format you want.
A date is always stored in the same manner in the DB.
When inserting you have to give the DB a format that it can parse as date. And when reading from the DB you can format the date in any way you like.
So you have to format your data before inserting into the correct format. Otherwise the DB can't store it as date.
You can go to different mysql website and get this answer. For Example:
http://www.tutorialspoint.com/mysql/mysql-date-time-functions.htm
SELECT STR_TO_DATE('21,5,2013','%d,%m,%Y');
I notice that MySQL save date as 0000-00-00 format. But in my application I have validate date for this 00-00-0000 format. I notice that date is not saving properly as different formats. Can I change mysql data format to 00-00-0000 format?
The 00-00-0000 format is not entirely clear; it could be dd-mm-yyyy for instance.
You can simply convert the date you have like so:
$mydate = '24-12-2012';
// create date object by using a known format
// see manual page for all format specifiers
$d = DateTime::createFromFormat('d-m-Y', $mydate);
// format date object in yyyy-mm-dd
echo $d->format('Y-m-d');
See also: DateTime::createFromFormat() DateTime::format()
You can also use MySQL str_to_date function
INSERT INTO yourtable (datefield) VALUES (str_to_date('01-02-2007', '%d-%m-%Y'));
As #Jack explained it is one of the correct way you can choose and
at the time of select date from database you can use
DATE_FORMAT(date,format).
You can't.
Instead of that you have to convert your custom format to database format and back.
To store it in the database you can use explode PHP function.
To when selecting, you can format mysql date format using DATE_FORMAT mysql function.
