Experts, I need to convert the time value as 0's in a datetime column leaving behind 00:00:00.000.

Sample data:

2019-04-17 08:47:51.433 
2019-04-17 00:00:00.000

Kindly suggest a key code. Thanks in advance!

As you appear to want to keep a time of 00:00:00.000 you could use

SELECT DATE_FORMAT('2019-04-17 08:47:51.433' , '%Y-%m-%d 00:00:00.000');


2019-04-17 00:00:00.000

I will assume that you really only want to view your datetime data this way. If so, then you should use DATE_FORMAT with a mask containing only the date portion:

    dt AS datetime,
    DATE_FORMAT(dt, '%Y-%m-%d') AS dateonly
FROM yourTable;

Unless you are certain that you would never need the time information, it makes no sense to throw that away.

8.1. datetime — Basic date and time types — Python 2.7.18 , date2 is moved forward in time if timedelta.days > 0 , or backward if the result is equivalent to tz.fromutc(datetime.utcnow().replace(tzinfo=tz)) . You can't change a DateTime value - it's immutable. However, you can change the variable to have a new value. The easiest way of doing that to change just the time is to create a TimeSpan with the relevant time, and use the DateTime.Date property:

How do I replace all missing values in a time series with a 0 , There are two main possibilities to achieve this: 1. The “Conversion settings” tab in Series List. You can set the “Missing Value Method” as “Zero Value”. 2. The TIMESTAMP WITH TIME ZONE datatype does adjust for the change, so the orderdate2 column shows the time as one hour earlier than the time shown in the orderdate1 column. Note: If you have created a global_orders table for the previous examples, then drop the global_orders table before you try Example 4-7 through Example 4-8 .

  • @timbiegeleisen, I'm not sure is it a good idea to change the meaning of the original post. It was not clear is the OP wants to keep 00:00:00.000 or not.
  • @mitkosoft You're right, sorry, I fixed it. For the record, my answer didn't even attempt to that anyway.
  • you missed .000 part :)
  • I'm applying it for the whole column, few dates are with time and few dates are 0's. So I need in 1 pattern like 0's in time. The above method occurred an error i.e 'date' is not a recognized built-in function name.
  • @SathishJay . . . date() is indeed a built-in MySQL function. Are you sure that is the database you are using?
