mysql - Infinidb -"` CREATE_TIMESTAMP` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP"给出错误

Question

我正在尝试将数据库从 mysql 移植到 infinidb。但是在移植时出现上述错误(在标题中描述)。

`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);

这是控制台输出

[root@centos6 bin]# idbmysql 
Welcome to the MySQL monitor.  Commands end with ; or \g.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

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

mysql> describe test;

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，您正在尝试使用哪个版本的 InfiniDB？

谢谢!
