Convert MySQL DATETIME to UNIX Timestamp

We can convert MySQL date and time to Unix Timestamp with the help of function UNIX_TIMESTAMP().

The following is the query.

mysql> SELECT UNIX_TIMESTAMP(STR_TO_DATE('Oct 19 2018 10:00PM', '%M %d %Y %h:%i%p'));

After running the above query we will not get the output in date format as shown in the below output. The output shown here is a Unix Timestamp.

+------------------------------------------------------------------------+
| UNIX_TIMESTAMP(STR_TO_DATE('Oct 19 2018 10:00PM', '%M %d %Y %h:%i%p')) |
+------------------------------------------------------------------------+
|                                                             1539966600 |
+------------------------------------------------------------------------+
1 row in set (0.04 sec)

To get the actual date/time, query is as follows.

mysql> SELECT FROM_UNIXTIME(UNIX_TIMESTAMP(STR_TO_DATE('Oct 19 2018 10:00PM', '%M %d %Y %h:%i%p')),'%m-%d-%Y %h:%i:%p');

The following is the output.

+-----------------------------------------------------------------------------------------------------------+
| FROM_UNIXTIME(UNIX_TIMESTAMP(STR_TO_DATE('Oct 19 2018 10:00PM', '%M %d %Y %h:%i%p')),'%m-%d-%Y %h:%i:%p') |
+-----------------------------------------------------------------------------------------------------------+
| 10-19-2018 10:00:PM                                                                                       |
