在session4的4小题需要用到SH.COUNTRIES表，而手工建库时，这个SH用户没有这个表，就想着将别处的这个表拷贝过来。
原来导出表的库：database ORACLE_SID=TEST0221 版本： 11.2.0.4 需要导进的库：database ORACLE_SID=PROD 版本：10.2.0.1 因为字符集的问题，出现了EXP-00091的错误 因为
数据库版本的问题，出现了IMP-00010的错误

The statistics are questionable because one or more of // the following happened during export: a row error occurred, client // character set or NCHARSET does not match with the server, a query // clause was specified on export, only certain partitions or // subpartitions were exported, or a fatal error occurred while // processing a table. // *Action: To export non-questionable statistics, change the client character // set or NCHARSET to match the server, export with no query clause, // export complete tables. If desired, import parameters can be // supplied so that only non-questionable statistics will be imported, // and all questionable statistics will be recalculated. [oracle@node2 ~]$ exit exit
