I used DATETIME datatype to store date and time in my Database. It saved date as
YY-MM-DD HH:MM:SS (2012-11-06 10:45:48)
I can retrieve the time from database as HH:MM:SS format but I want to retrieve it in HH:MM format.
How can I do this?
Check the DATE_FORMAT Function.
SELECT DATE_FORMAT(date_column, '%H:%i') FROM your_table
You will want to use DATE_FORMAT():
select date_format(yourDateColumn, '%h:%i') yourTime
from yourtable
See SQL Fiddle with Demo
SELECT DATE_FORMAT( NOW() , '%H:%i' ) AS time_column

I need to convert a date in format dd.mm.yyyy to yyyy-mm-dd
For example, if the date is 04.12.2020, i want it to be like 2020-12.04(which is 4th december)
But the command giving me the output as 2020-04-12( which is 12th April)
select convert(date,'04.12.2020' )
I think you just want str_to_date():
select str_to_date('04.12.2020', '%d.%m.%Y')
It sounds like you have a date as a string? (ie. the "04.12.2020").
MySql has a STR_TO_DATE() function:
select str_to_date('04.12.2020', '%d.%m.%Y')
That should convert it to an actual date datatype.
If needed an actual date can then be formated in which ever way you want or just visualized depending on what you're trying to do with DATE_FORMAT():
select date_format(date, '%Y-%m-%d')
My current date formats are 01/01/2013 .... DD/MM/YYYY
How can I convert them all into MYSQL dates? I'm under The impression they are in the format YYYY-MM-DD
I don't know where to start.
my problem is that the dates are being ordered in the american way whilst they are in british format :(
Use the following query.
update tbl_name set your_field_name= str_to_date(your_field_name, '%d/%m/%Y');
It will update the value of your date from DD/MM/YYYY to YYYY/MM/DD.
Then you can change your filed type to date.
You can extract each part in php and concat the dd, mm, yyyy and save it to the DB
Why not DATE_FORMAT
DATE_FORMAT(date,'%Y-%m-%d')
How to convert date in MYSQL to correct format:
SELECT DATE_FORMAT(column_name, '%d/%m/%Y') FROM tablename
or
SELECT t.id, DATEDIFF(STR_TO_DATE(t.carddate, '%m/%d/%Y'), CURDATE)
FROM TABLE t

I have a very similar situation. I converted American date format "%Y-%d-%m" to correct format '%Y-%m-%d'. This is how I did it...
update table_name set my_date = DATE_FORMAT( STR_TO_DATE( my_date, '%Y-%d-%m' ) , '%Y-%m-%d' );
The first date string format '%Y-%d-%m' needs to be how the date is currently formatted in your table. The second date string is what you want to convert it to.
I've got a date format in a bigint field in this format "20130314123743" - YYYYMMDDHHMMSS and i need to do a mysql query on it and get it back to the user in something like yyyy-mm-dd hh:mm:ss.
Is there a native mysql function that will take that date format and return it to something human readable?
One approach:
select cast(cast(bigintdateval as char(14)) as datetime)
SQLFiddle here.
To convert to a datetime you can use MySQL function FROM_UNIXTIME
FROM_UNIXTIME (unix_timestamp, [format ])
SELECT FROM_UNIXTIME(20130314123743, '%Y-%m-%d %h:%i:%s');
Exemple;
SELECT FROM_UNIXTIME(birthDay/100000, "%Y-%m-%d %H:%i:%s") AS date
FROM person;

FROM_UNIXTIME
Hope that help
I have timestamps in varchar(20) like '01-11-2012 11:36:53.122'
If I get only date by
SELECT STR_TO_DATE("01-11-2012 11:36:53.122", '%d-%m-%Y')
it gives this output: "2012-11-01".
But by this
SELECT STR_TO_DATE("01-11-2012 11:36:53.122", '%H:%i:%s')
it gives the output "null" instead of 11:36:53.
What is query to get only the time?
give this a try
DATE_FORMAT(STR_TO_DATE(`column`, '%d-%m-%Y %H:%i:%s'), '%H:%i:%s')

Other sources,
STR_TO_DATE
DATE_FORMAT
SELECT date_format(STR_TO_DATE("01-11-2012 11:36:53.122", '%d-%m-%Y %H:%i:%s.%f'), '%H:%i:%s')

Change your field format to datetime.
That's the only proper way to store datetime values.
How to convert 1300464000 to 2011-03-18 16:00:00 in MySQL?
Use the FROM_UNIXTIME() function in MySQL
Remember that if you are using a framework that stores it in milliseconds (for example Java's timestamp) you have to divide by 1000 to obtain the right Unix time in seconds.
DATE_FORMAT(FROM_UNIXTIME(`orderdate`), '%Y-%m-%d %H:%i:%s') as "Date" FROM `orders`
This is the ultimate solution if the given date is in encoded format like 1300464000
To answer Janus Troelsen comment
Use UNIX_TIMESTAMP instead of TIMESTAMP
SELECT from_unixtime( UNIX_TIMESTAMP( "2011-12-01 22:01:23.048" ) )
The TIMESTAMP function returns a Date or a DateTime and not a timestamp, while UNIX_TIMESTAMP returns a unix timestamp
You can use
select from_unixtime(1300464000,"%Y-%m-%d %h %i %s") from table;
For in details description about
from_unixtime()
unix_timestamp()
SELECT from_unixtime( UNIX_TIMESTAMP(fild_with_timestamp) ) from "your_table"
This work for me
