Is there any MySQL function to return date from unix time stamp?

Tuesday, July 14, 2015


In the DB table, when a record is inserted the timestamp is also inserted.
This time stamp is added in the insert query using the time() function.
When The records are listed currently the php date( $timestamp , "d/m/Y h:i:s" ) function is used to dhow the data back.

Is there any function in MYSQL which can  generate date from the unix timestamp stored in the table?


Answer is YES!!!! ;)

You can use the MySQL function FROM_UNIXTIME() for getting date from the unix timestamp in MySQL table.

Example

mysql> SELECT FROM_UNIXTIME(1436716249);
-> '2015-07-12 10:30:19'

If the time stamp is stored in the field "InsertTimeStamp" , then here is the sample query to access it:

mysql> SELECT
from_unixtime( InsertTimeStamp , '%Y %D %M %h:%i:%s')
FROM
your_table_name

Another Example:

mysql> Select OrderNo, ApplicantName , from_unixtime( AppEntryTimeStamp , '%Y %D %M %h:%i:%s %p %a') as AppTime from tbl_Orders order by OrderNo Desc
