一、Oracle 数据导出: (1、 将数据库linuxidc 的数据完全导出, 数据库的用户名 linuxidc ,密码 linuxidc ,导出到本地 E:\data.

一、Oracle 数据导出:

(1、 将数据库linuxidc 的数据完全导出, 数据库的用户名 linuxidc ,密码 linuxidc ,导出到本地 E:\data.dmp 中

exp linuxidc/linuxidc@linuxidc file=E:\data.dmp full=y

(2、将数据库中 linuxidc 用户与 sys 用户的表导出

exp linuxidc/linuxidc@linuxidc file=E:\data.dmp owner=(linuxidc,sys)

(3、将数据库中的表 table1、table2 导出

exp linuxidc/linuxidc@linuxidc file= E:\data.dmp tables=(table1,table2)

(4、 将数据库中的表table1中的字段area 值为"南昌"的数据导出

exp system/manager@TEST file=E:\data.dmp tables=(table1) query=\" where area ='南昌' \"

以上命令可以应付常用的导出,,若想将导出的数据文件dmp进行压缩,可以用zip或WinRAR,也可以在上面命令后面追加命令参数 compress=y 来实现压缩。

二、Oracle 数据导入:

(1、将E:\data.dmp 中的数据导入 linuxidc数据库中。

imp linuxidc/linuxidc@linuxidc file=E:\data.dmp

再导入过程中可能会遇到一些警告或问题,比如有的表已经存在,那么它就报错,对该表就不进行导入。这时导入操作将会停止,但我们想继续后续的导入,那么可以在后面加上 ignore=y 略过警告、问题:

imp linuxidc/linuxidc@linuxidc full=y file=E:\data.dmp ignore=y
