Question

我正在使用MySQL。我通过phpMyAdmin将我的db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 MySQL时，我收到以下错误：

第29行的错误1064（42000）：您的SQL语法出错;   检查与您的MySQL服务器版本对应的手册   正确的语法在'（6）NOT NULL DEFAULT CURRENT_TIMESTAMP（6）附近使用，
  cId int（11）DEFAULT NULL）第4行的引擎'

这是SQL：

Answer 1

数据类型datetime没有可变长度。请删除(6)

`v2` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP

Answer 2

在讨论了ClearDB支持的问题之后：

问题是相关的ClearDB集群运行mysql 5.5，而对于mysql 5.6.5及以下版本，则适用：
