I want to store and display date in this format "1.1.1990", (d.m.Y)
I've got a date column in my database with these settings
TYPE: DATE
Browser display transformation: Date Format(text/plain: Dateformat)
Browser display transformation options: 0,'%j.%n.%Y','local'
My query goes as :
INSERT INTO table VALUES(STR_TO_DATE('1.1.1990', '%e.%c.%Y'))
So far the query is accepted but a blank field is displayed in database
Only other thing i could get is without using STR_TO_DATE to add a default date as 1.1.1970
You have to set the column in date type
You can ensure the date is wellformed: select STR_TO_DATE('1.1.1990', '%e.%c.%Y');

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.
I'm having some troubles dealing with Timestamp data type in MySQL.
I'm saving simple records in my database using a simple DB structure, like:
ID int
Name varchar
Date timestamp
Text varchar
And then retrieve them with something like:
SELECT * FROM table WHERE Date BETWEEN '2013-01-01' AND '2013-06-30'
Everything works fine if I store records letting MySQL fill the Date field with the actual timestamp, for example: 2013-10-04 22:40:02 which means I don't add any value to the Date field in my INSERT query.
But I need to be able to add the date by my self since my application needs to store the date from where the application started, and not the date and time in which the query was sent to the database.
So what I do is I create the same date/time format my Date field uses which is 2013-10-04 22:40:02 and then do a simply insert:
INSERT INTO table (Name, Date, Text)
VALUES ('Peter', '2013-10-04 22:40:02', 'Hello...')
Now, doing it this way I'm unable to bring any result by date using a select query like this one:
SELECT * FROM table WHERE Date BETWEEN '2013-01-01' AND '2013-11-30'
Even if I try to sort results by Date using PHPMyAdmin interface, all the records that contain manually added dates disappear. If I sort them by ID, they re-appear. I checked and the dates and formats are correct. So I have no idea what the problem could be. I'm new at MySQL by the way.
Hope you can give me a hand. Thanks!
Well, I think I found the problem and it has nothing to do with PHP and MySQL, the problem is that I generate the date with JavaScript, and it's giving the wrong month.. :/
Thanks to everyone anyway!
PROBLEM
I need I safely convert the date format in the mySQL database table MYTABLE from the actual datetime format field date: e.g. 2013-09-10 12:43:03, to its unix timestamp equivalent: 1378816983 without compromising the existing thousands of articles already in the database.
I am using PHP, mySql, Drupal.
MY APPROACH
My steps
Alter the table field type from datetime to timestamp [DONE]
Converting the actual content type field: timestamp [DONE]
Converting existing article data field in 4 tables using PHP strtotime() or MYSQL: UNIX_TIMESTAMP(date)
I NEED HELP ON PT.3
A. a little help on the algorithm at the pt. 3:
e.g.
loop over all 4 tables {
- create a new column date2 of type: int (or datetime?)
- copy all dates from date to date2 passing them through strtotime()
- delete column date
- rename column date2 to column date
}
backup the table
check if backup is all right and safe
Alter the table field type from datetime to varchar
update table set field=unix_timestamp(field)
Alter the table field type from varchar to int
However I wouldn't do such a conversion at all
First off, the safest way to convert data like this is to not do it on the fly.
The first thing that I would do would be to add another column to your table. Then given that we aren't modifying existing data, I would look at using the Unix_timestamp mysql function. If you are storing the data in a date datatype already, it seems that it is nice and safe for mysql to do it.
Given that, it seems to be a simple matter of running something like:
update MyTable set newtimeStampColumn=UNIX_TIMESTAMP(oldDateColumn);
and see how it works. You can then run some comparison queries to ensure that all your data has converted corectly.
I am trying to insert a date into an SQL table using a php script. I am generating the date in php using the following code:
Date("l F d, Y");
If I set the format of the 'dat' column format in my SQL table to string the date is entered correctly however if I set the column format to date the date appears as
0000-00-00
Any help?
The DATE and date-related data types store date values in an internal structure. The formatting of the date value you entered is not preserved. When saving to a string data type, it's just a string. No date knowledge is saved.
When you SELECT the data from a DATE column, the default format for display is 0000-00-00. You can format the value (technique depends on the DBMS) when you SELECT the data.
In MYSQL database, I have the date column which contains date in format [29-11-2012].
I would like to display the values based upon month selected by user via php page.
For Example, If user selects OCT then this should display all the other columns for this particular month.
Can you suggest SQL Query for this?
Thanks,
Shail
You can use
WHERE MONTH(STR_TO_DATE(formdate,'%d-%m-%Y'))
like this condition
Basically mysql stores dates in yyyy-mm-dd format only..
