I have a query selecting time in the format where the time column is of the DateTime datatype.
SELECT ul.time FROM user_logins;
It is returning the result in this format-
11/27/2021 9:29:46 AM
11/23/2021 12:48:20 PM
Now I want it to return in the 24 hour format like
11/27/2021 9:29:46 11/23/2021 00:48:20
Is there any possible way to achieve that?
DATETIME values always stored in 24 hour format. As your column defined as DATETIME datatype, it's in 24 hour format
Output of DATETIME datatype:
2021-12-07 18:21:30.907
AM / PM is not mentioned by DATETIME, So We can format it.
Query: Select CONVERT(varchar,GETDATE(),9)
Output: Dec 7 2021 7:26:55:077PM

If I store timestamp 1625555827900 in 2 separate fields whose format are dateonly and date,
will there be any difference?
You can not store the unix timestamps in both of the fields as their types are DATEONLY and DATE. Sequelize will through an error
DatabaseError [SequelizeDatabaseError]: date/time field value out of range: "1625555827900"
First you need to format the date like Tue Jul 06 2021 07:55:33 or 2021-07-06 07:55:33 in your code. In that case, it will save the complete date 2021-07-06 07:55:33.000000 for DATE field and skip the time part for DATEONLY field 2021-07-06.
Or you can use BIGINT instead if you are intended to store the unix timestamps.
I have a table alert_log has column name date_dt (type varchar 50) which stores unix timestamp data
example data : 1518783503000
select FROM_UNIXTIME(date_dt) AS 'date_formatted' from alert_log
it always returns null.please help i would like to convert the example unix data as Fri Feb 16 2018
That is because 1518783503000 is not a valid MySQL unix time.
Divide by 1000 to get it right because unix time is in seconds and you stored it in milliseconds.
select FROM_UNIXTIME(date_dt / 1000) AS 'date_formatted'
from alert_log
I currently have a table, where three columns, named Start_Time, End_Time, and Scheduled_Time all have data format of Datetime where the format is YYYY-MM-DD 12:00:00 (24 hour clock). How would I be able to convert these columns where it would display as MM-DD_YYYY 12:00:00 (AM/PM) clock?
I believe that if you have a table with a column such as datefield DATETIME, in your select statement, if you CAST(datefield AS VARCHAR(20)), this will give you the proper time you are looking for(AM, and PM)
Testing it out myself I went from datefield being 2014-07-30 16:44:00 to Jul 30 2014 4:44PM by using CAST()
How to query data in specific time like: I want to select all records stored between 1 pm and 5 pm during a month , when the time stored in datetime column in Unix timestamp format like so "1403830861".
The FROM_UNIXTIME function can convert a unix timestamp to a date. The %k format (hour represented as an in 0..23) seems to fit the bill nicely. The month could be easily extracted in the same fashion, using the %m format and the year using %Y. E.g., the following query would return only results from November 2014:
SELECT *
FROM my_table
WHERE FROM_UNIXTIME (timestamp_column, '%k') BETWEEN 13 AND 17 AND
FROM_UNIXTIME (timestamp_column, '%m') = 11 AND
FROM_UNIXTIME (timestamp_column, '%Y') = 2014
I am trying to import data from a csv file to a mysql table. One of the columns contains a serialized date (it came from another mysql table) which I need to convert to a format yyyy-mm-dd hh:mm:ss.000000. An example serial date is "1389792682". I tried converting in Excel but none of the custom formats recognize the number as a date - I believe because it's a date-time number. Any ideas?
Thanks
I think that you can use this formula in order to convert this timestamp to a date. Supposing your timestamp is in A1 cell:
=((A1/3600)/24) + DATE(1970,1,1)
This is because Unix epoch is the time 00:00:00 UTC on 1 January 1970.
And then chose to format your cell as a date.
The timestamp that you specifies in your question gives me:
year: 2014
month: 01
day: 15
h: 13:31
1389792682 corresponds to 2014-01-15 05:31:22 -0800 (2014-01-15 13:31:22 UTC) in Unix/Linux time.
It can be converted to a date field with
DATE_ADD('1970-01-01', INTERVAL 1389792682 SECONDS)
