我有以下表模式;

CREATE TABLE `db1`.`sms_queue` (
  `Id` INTEGER UNSIGNED NOT NULL AUTO_INCREMENT,
  `Message` VARCHAR(160) NOT NULL DEFAULT 'Unknown Message Error',
  `CurrentState` VARCHAR(10) NOT NULL DEFAULT 'None',
  `Phone` VARCHAR(14) DEFAULT NULL,
  `Created` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
  `LastUpdated` TIMESTAMP NOT NULL ON UPDATE CURRENT_TIMESTAMP,
  `TriesLeft` tinyint NOT NULL DEFAULT 3,
  PRIMARY KEY (`Id`)
)
ENGINE = InnoDB;

它失败并出现以下错误:

ERROR 1293 (HY000): Incorrect table definition; there can be only one TIMESTAMP column with CURRENT_TIMESTAMP in DEFAULT or ON UPDATE clause.

我的问题是,我可以同时拥有这两个领域吗？或者我必须在每次交易期间手动设置LastUpdated字段？
