在cmd下使用imp命令导入oracle的dmp文件报错ORA-02304

报错信息如下：

IMP-00017: 由于 ORACLE 错误 2304, 以下语句失败:
 "CREATE TYPE "EN_CONCAT_IM" TIMESTAMP '2018-04-09:16:01:30' OID '27A29B9B634"

IMP-00003: 遇到 ORACLE 错误 2304
ORA-02304: 无效的对象标识符文字

报这个错的原因是因为自定义type的标准创建语句是：

create type 变量 as table of 类型

--

create type 变量 as object(

字段1 类型1,

字段2 类型2

);

但是上面的sql是exp直接导出的，包含了时间戳和OID，打开PLSQL，注释掉时间戳和OID后，执行上述语句不报错，问题解决。
