How to save time in milliseconds in MySQL?

To save time in milliseconds, we can use now(3) function because “milli 3” can be used for te same purpose. Firstly, I will create a table with the help of CREATE command −

mysql> CREATE table MilliSecondDemo
-> (
-> MyTimeInMillSec datetime(3)
-> );
Query OK, 0 rows affected (0.70 sec)

Inserting record into the table −

mysql> INSERT into MilliSecondDemo values(now(3));
Query OK, 1 row affected (0.98 sec)

Let us now view the table records −

mysql> SELECT * from MilliSecondDemo;

The following is the output

+-------------------------+
| MyTimeInMillSec         |
+-------------------------+
| 2018-10-08 15:19:50.202 |
+-------------------------+
1 row in set (0.00 sec)
