How to retrieve microseconds or milliseconds from MySQL current time?

Question

I am trying to create my first stored function on MySQL. In this function I want to return the timestamp of the current date and time with 3 microsecond digits like this:

Answer 1

MySQL 5.6 supports the millisecond precision in the sysdate function.

try

select sysdate(6) will return 2013-04-16 13:47:56.273434

and

select sysdate(3) will return 2013-04-16 13:47:56.273
