将 SQL 导入 ClearDB MySQL 时出错

Question

我正在使用 MySQL。我通过 phpMyAdmin 将我的数据库表导出到 sql 文件。我通过 phpMyAdmin 在本地导入该文件没有问题，但是当我尝试将其导入 ClearDB 时 MySQL 我收到以下错误：

ERROR 1064 (42000) at line 29: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '(6) NOT NULL DEFAULT CURRENT_TIMESTAMP(6),
cId int(11) DEFAULT NULL ) ENGINE' at line 4

这是SQL：

Answer 1

数据类型datetime没有可变长度。所以删除 (6)

`v2` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP

Answer 2

在与 ClearDB 支持人员讨论该问题后：

问题是相关的 ClearDB 集群运行 mysql 5.5，而 mysql 5.6.5 及以下适用：

"CURRENT_TIMESTAMP is only acceptable on TIMESTAMP fields. DATETIME fields must be left either with a null default value, or no default value at all - default values must be a constant value, not the result of an expression."
