MySQL CURRENT_TIMESTAMP 在创建和更新时

MySQL CURRENT_TIMESTAMP on create and on update(MySQL CURRENT_TIMESTAMP 在创建和更新时)

问题描述

我想定义有 2 个 TIMESTAMP 字段的表，如下所示:

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
)

如何避免错误:

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

重点是在表模式中保持 ts_create 和 ts_update 的期望行为.

Point is to keep desired behavior of ts_create and ts_update in table schema.

推荐答案

猜这是一篇老帖子，但实际上我猜 mysql 在其最近的版本中支持 2 TIMESTAMP mysql 5.6.25 这就是我现在使用的.

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.
