Question

I want to add expire TIMESTAMP in DB table. I have one field timestamp with type TIMESTAMP and default value CURRENT_TIMESTAMP(). I adding new field “expire” with type DATETIME with default value ADDDATE(CURRENT_TIMESTAMP, INRERVAL 1 DAY), but not working.

CREATE TABLE IF NOT EXISTS `temp_mch` (
  `name` varchar(60) NOT NULL,
  `qty_new` int(5) NOT NULL,
  `timestamp` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY (`name`),
  KEY `name` (`name`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1

Where I’m wrong ?

Thanks in advance !

That is not supported in the column default definition.

You can use a trigger to do it instead.
