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" "1AD1EE050FD0AD4021A7C\' " " " " " " AUTHID CURRENT_USER AS OBJECT" "(" " CURR_STR VARCHAR2(32767)," " STATIC FUNCTION ODCIAGGREGATEINITIALIZE(SCTX IN OUT en_concat_im) RETUR" "N NUMBER," " MEMBER FUNCTION ODCIAGGREGATEITERATE(SELF IN OUT en_concat_im," " P1 IN VARCHAR2) RETURN NUMBER," " MEMBER FUNCTION ODCIAGGREGATETERMINATE(SELF IN en_concat_im," " RETURNVALUE OUT VARCHAR2," " FLAGS IN NUMBER)" " RETURN NUMBER," " MEMBER FUNCTION ODCIAGGREGATEMERGE(SELF IN OUT en_concat_im," " SCTX2 IN en_concat_im) RETURN NUMBER" " );" "" 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。
