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

The correct way of extracting miliseconds from a timestamp value on PostgreSQL accordingly to current documentation is:

SELECT date_part('milliseconds', current_timestamp);

--OR

SELECT EXTRACT(MILLISECONDS FROM current_timestamp);

with returns: The seconds field, including fractional parts, multiplied by 1000. Note that this includes full seconds.
