I have to develop a application using MySQL and I have to save values like "1412792828893" which represent a timestamp but with a precision of a millisecond. That is, the amount of milliseconds since 1.1.1970. I declare the row as timestamp
but unfortunately this didn't work. All values are set to 0000-00-00 00:00:00
CREATE TABLE IF NOT EXISTS `probability` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`segment_id` int(11) NOT NULL,
`probability` float NOT NULL,
`measured_at` timestamp NOT NULL,
`provider_id` int(11) NOT NULL,
PRIMARY KEY (`id`)
) ;
How should be the declaration in order to be able to save timestamp values with this precision?
This question is related to

You can use BIGINT as follows:
CREATE TABLE user_reg (
user_id INT NOT NULL AUTO_INCREMENT,
identifier INT,
phone_number CHAR(11) NOT NULL,
verified TINYINT UNSIGNED NOT NULL,
reg_time BIGINT,
last_active_time BIGINT,
PRIMARY KEY (user_id),
INDEX (phone_number, user_id, identifier)
);
CREATE TABLE fractest( c1 TIME(3), c2 DATETIME(3), c3 TIMESTAMP(3) );
INSERT INTO fractest VALUES
('17:51:04.777', '2018-09-08 17:51:04.777', '2018-09-08 17:51:04.777');
