How do I gracefully solve a problem in MySQL that is accurate to milliseconds?

Just done, no two fields are needed. mysql5.6.4 later versions, support defining a field such as time (3) or timestamp (6), and then using Current_timestamp (6), you can assign a value with a millisecond or microsecond value to the field! posted on 2015-08-27 I'm also studying the problem. All seem to be two fields to implement.

The general search is to use two fields to achieve, this is known to say 5.6.4 after the can.

In fact, you can also use a string to save, and the time string to milliseconds can be the master key.
