Mysql Infinidb-“`在更新当前时间戳时创建“时间戳非空默认当前时间戳”；给出错误

我试图将一个数据库从mysql移植到infinidb，但在移植过程中出现了上述错误（如标题所述）

`CREATE_TIMESTAMP` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP

---

在mysql中有效，但在infinidb中无效。错误是：错误代码：138。infinidb不支持语法或数据类型。任何帮助都将不胜感激。

这是您尝试的完整SQL语句吗？我能够使用：

create table test (`CREATE_TIMESTAMP` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP);

这里是控制台输出

如果这不起作用或者您正在以不同的方式尝试语法，请告诉我。另外，您正在尝试什么版本的InfiniDB

谢谢

看起来您无法将TimePSamp数据类型与InfiniDB一起使用。我的版本与@mhoglan相同，但该查询中似乎有一点错误：

mysql> create table test (`CREATE_TIMESTAMP` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP);
Query OK, 0 rows affected (0.00 sec) 

末尾缺少“engine=infinib；”“，这将在infinib中创建表。 相反，该表是使用MySQL的默认引擎（MyISAM或其他任何引擎）创建的

如您所见，添加engine=infinidb失败

---

如果你可以改用datetime，那可能是最好的选择；时间戳目前似乎不受支持：（

我想这是InfiniDB中不允许的NOTNULL约束。
