CURRENT_TIMESTAMP in milliseconds

Question

Is there any way to get milliseconds out of a timestamp in MySql or PostgreSql (or others just out of curiosity)?

SELECT CURRENT_TI         


        

Answer 1

I felt the need to continue to refine, so in MySQL:

Current timestamp in milliseconds:

floor(unix_timestamp(current_timestamp(3)) * 1000)

Timestamp in milliseconds from given datetime(3):

floor(unix_timestamp("2015-04-27 15:14:55.692") * 1000)

Convert timestamp in milliseconds to datetime(3):

from_unixtime(1430146422456 / 1000)

Convert datetime(3) to timestamp in milliseconds:

floor(unix_timestamp("2015-04-27 14:53:42.456") * 1000)
