MySQL CURRENT_TIMESTAMP on create and on update
I want to define table which will have 2 TIMESTAMP fields, someting like this:
CREATE TABLE `msgs` (
`id` INT PRIMARY KEY AUTO_INCREMENT,
`msg` VARCHAR(256),
`ts_create` TIMESTAMP DEFAULT CURRENT_TIMESTAMP,
`ts_update` TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
)
How to do this avoiding error:
ERROR 1293 (HY000): Incorrect table definition; there can be only one TIMESTAMP column with CURRENT_TIMESTAMP in DEFAULT or ON UPDATE clause
Point is to keep desired behavior of ts_create
and ts_update
in table schema.
Solution 1:
Guess this is a old post but actually i guess mysql supports 2 TIMESTAMP in its recent editions mysql 5.6.25 thats what im using as of now.
Solution 2:
i think it is possible by using below technique
`ts_create` timestamp NOT NULL DEFAULT '0000-00-00 00:00:00',
`ts_update` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP
Solution 3:
You are using older MySql version. Update your myqsl to 5.6.5+ it will work.
Solution 4:
You cannot have two TIMESTAMP column with the same default value of CURRENT_TIMESTAMP on your table. Please refer to this link: http://www.mysqltutorial.org/mysql-timestamp.aspx
