select from_unixtime(floor(1510156036741/1000), '%Y %D %M %h:%i:%s');
'2017 8th November 07:47:16'
The above code outputs a timestamp which doesn't include millisecond precision. How would I convert an unix epoch time to a datetime(3) object which includes milliseconds?
It's possible to get microseconds like:
select from_unixtime(1510156036741/1000, '%Y %D %M %h:%i:%s %f');
'2017 8th November 07:47:16 741000'
Is it possible to convert the microsecond result to milliseconds?
Its a bit clunky, but you can extract the microsecond and divide it by 1000 to convert it to milliseconds. Here I've also cast it to an int and concatinated it with the formatted date to create the final date string:
SELECT CONCAT(
from_unixtime(1510156036741/1000, '%Y %D %M %h:%i:%s '),
CAST(EXTRACT(MICROSECOND FROM from_unixtime(1510156036741/1000))/1000
AS SIGNED)
);

I have database which contains string like this
22 Jan 2019 11:03
I would like to convert this string to date so I apply this query
select DATE_FORMAT(STR_TO_DATE('22 Jan 2019 11:03','%d-%m-%Y') ,'%d-%m-%Y');
but I get a null result
All you have to do is change small letter m to big letter M in your str_to_date function.
select STR_TO_DATE('22 Jan 2019 11:03','%d %M %Y');
so the final query would be:
select DATE_FORMAT(STR_TO_DATE('22 Jan 2019 11:03','%d %M %Y') ,'%d-%m-%Y');
Here is a demo
SELECT STR_TO_DATE('22 Jan 2019 11:03','%d,%m,%Y');
Basically you first need to understand the values to pass in STR_TO_DATE() and DATE_FORMAT() functions
STR_TO_DATE(my date string , current format of my date string)
Now what you are not doing right is that in STR_TO_DATE() you are passing the format '%d-%m-%Y' , this format says that the input string has hyphen separated date month and year values which is not true.
Now in your case the actual format of your date string is the following
'%d %M %Y %h:%i'
STR_TO_DATE('22 Jan 2019 11:03','%d %M %Y %h:%i')
%d - day
%M - month
%Y - year
%h - hour
%i - minute

Now that we have a complete valid value from string to date including hour and minutes, we can convert this date into any of our required format using correct parameters
SELECT DATE_FORMAT(STR_TO_DATE('22 Jan 2019 11:03','%d %M %Y %h:%i') ,'%d-%m-%y %h:%i');

I have a column in a MySQL database that has dates in the form:
Tue Oct 25 2016. I am trying to get it in the form 10/25/2016.
I did some research and tried this:
SELECT DATE_FORMAT(Date, '%d/%m/%Y') FROM table;
But it is returning null
Any help would be greatly appreciated.
Firstly, you will need to convert your date string to MySQL date format ('YYYY-MM-DD'), using STR_TO_DATE function. To convert from string, we have to specify the current format of the date string. In your case, it is '%a %b %d %Y'. Note that the % character is required before format specifier characters.
Details:
%a Abbreviated weekday name (Sun to Sat)
%b Abbreviated month name (Jan to Dec)
%d Day of the month as a numeric value (01 to 31)
%Y Year as a numeric, 4-digit value
Now, you can utilize DATE_FORMAT function to convert the MySQL date into the desired date string format. In your case, it will be: '%m/%d/%Y'
Details:
%d Day of the month as a numeric value (01 to 31)
%m Month name as a numeric value (00 to 12)
%Y Year as a numeric, 4-digit value
Try the following query:
SELECT DATE_FORMAT(STR_TO_DATE(Date, '%a %b %d %Y'), '%m/%d/%Y')
FROM table;

I have a varchar dating field that reads as so - xx/xx/xxxx
I need to return the max as xx/xx/xxxx AM(or PM)
I can't figure out how to get it to return the max correctly while including AM/PM
I have been playing around with
SELECT DATE_FORMAT(max(STR_TO_DATE(pg_date_, '%c/%e/%Y %H:%i')), '%Y-%m-%d %H:%m:%s') from cas_compliance.failedrefunds2
I can't get to return quite the way I need it.
Thanks!
To convert xx/xx/xxxx to xx/xx/xxxx AM(or PM), you can try the following:
SELECT DATE_FORMAT(MAX(STR_TO_DATE(pg_date_,
'%c/%e/%Y %H:%i')
),
'%c/%e/%Y %r')
FROM cas_compliance.failedrefunds2
Details:
%r Time in 12 hour AM or PM format (hh:mm:ss AM/PM)
%H Hour (00 to 23)
%i Minutes (00 to 59)
%c Numeric month name (0 to 12)
%e Day of the month as a numeric value (0 to 31)
%Y Year as a numeric, 4-digit value
select DATE_FORMAT(now(), "%d-%m-%y %r");
Convert your date using above formating will solve problem.
I am new to mysql. I need to insert the string '2014-07-10 13:33:33' into the table column which has datetime datatype.
I gave like this,
SELECT STR_TO_DATE('2014-07-09 23:30:00', '%Y/%m/%d %h:%m:%s');
But i didn't not give the result.
How to do this?
Minutes is %i, not %m and 24-hour format is %H, not %h:
SELECT STR_TO_DATE('2014-07-09 23:30:00', '%Y-%m-%d %H:%i:%s');
Shouldnt it be
SELECT STR_TO_DATE('2014-07-09 23:30:00', '%Y-%m-%d %H:%i:%s');
%Y for year numeric, four digits
%m for month numeric
%d for Day of the month, numeric
%H for 24 hours
%i for minutes
%s for seconds
How do I convert the following format to unix timestamp?
Apr 15 2012 12:00AM
The format I get from DB seems to have AM at the end.
I've tried using the following but it did not work:
CONVERT(DATETIME, Sales.SalesDate, 103) AS DTSALESDATE,
CONVERT(TIMESTAMP, Sales.SalesDate, 103) AS TSSALESDATE
where Sales.SalesDate value is Apr 15 2012 12:00AM
Here's an example of how to convert DATETIME to UNIX timestamp:
SELECT UNIX_TIMESTAMP(STR_TO_DATE('Apr 15 2012 12:00AM', '%M %d %Y %h:%i%p'))
Here's an example of how to change date format:
SELECT FROM_UNIXTIME(UNIX_TIMESTAMP(STR_TO_DATE('Apr 15 2012 12:00AM', '%M %d %Y %h:%i%p')),'%m-%d-%Y %h:%i:%p')
Documentation: UNIX_TIMESTAMP, FROM_UNIXTIME
You will certainly have to use both STR_TO_DATE to convert your date to a MySQL standard date format, and UNIX_TIMESTAMP to get the timestamp from it.
Given the format of your date, something like
UNIX_TIMESTAMP(STR_TO_DATE(Sales.SalesDate, '%M %e %Y %h:%i%p'))
Will gives you a valid timestamp. Look the STR_TO_DATE documentation to have more information on the format string.
If you want to create a timestamp as returned by java's Date.getTime() you should multiply by 1000.
SELECT UNIX_TIMESTAMP(STR_TO_DATE('Apr 15 2012 12:00AM', '%M %d %Y %h:%i%p'))*1000
Now for a more standard date format use:
SELECT UNIX_TIMESTAMP(STR_TO_DATE('2022-12-14 20:58:00', '%Y-%m-%d %H:%i:%s'))*1000
From http://www.epochconverter.com/
SELECT DATEDIFF(s, '1970-01-01 00:00:00', GETUTCDATE())
My bad, SELECT unix_timestamp(time) Time format: YYYY-MM-DD HH:MM:SS or YYMMDD or YYYYMMDD. More on using timestamps with MySQL:
