原來導出表的庫：database ORACLE_SID=TEST0221 版本： 11.2.0.4
需要導進的庫：database ORACLE_SID=PROD 版本：10.2.0.1
因為字符集的問題，出現了EXP-00091的錯誤
因為數據庫版本的問題，出現了IMP-00010的錯誤

導出dmp文件信息：

00091, 00000, "Exporting questionable statistics."
// *Cause: Export was able export statistics, but the statistics may not be
// usuable. 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.
