Oracle 备份、恢复单表或多表数据步骤,适用于 Oracle 8、9、10。

Oracle 备份、恢复单表或多表数据步骤,适用于 Oracle 8、9、10。

*备份单表或多表数据:

exp user/password@server file=filefullpathname log=logfullpathname tables=(tablespacename.table1,tablespacename.table2,...)

例如,作者要导出用户名为 sybj,密码为 sybj,sid 为 lyzz,表空间 sybj 下表 table1、table2 中的数据,win 下 CMD 命令如下:

F:/oralce/ora92/bin>exp sybj/sybj@lyzz file=G:/tmps/test009.tmp log=G:/tmps/test009.log tables=(sybj.table1,sybj.table2)

备份文件 test009.tmp 将会在目录 G:/tmps/ 下生成。

*单表或多表数据恢复:

如果被恢复的表已经存在,应该先将其删除,不然报“IMP-0015”错误,,导入失败。单表或多表数据恢复命令如下:

imp user/password@server file=filefullpathname log=logfullpathname full=y

仍以上面的例子,将 table1、table2 数据恢复,win 下 CMD 命令如下:

F:/oralce/ora92/bin>imp sybj/sybj@lyzz file=G:/tmps/test009.tmp log=G:/tmps/test009imp.log full=y
