导入导出实例:

以下所有命令均在DOS窗口中输入!

用户的创建参考:http://blog.csdn.net/gateway6143/article/details/41212823

  

一、数据导出:

  1、 将数据库TEST完全导出,用户名system 密码manager 导出到D:\daochu.dmp中

  exp system/manager@TEST file=d:\daochu.dmp full=y

  2、 将数据库中system用户与sys用户的表导出 (含表、存储过程、视图等)

  exp system/manager@TEST file=d:\daochu.dmp owner=(system,sys)

  3、 将数据库中的表table1 、table2导出

  exp system/manager@TEST file=d:\daochu.dmp tables=(table1,table2)

  4、 将数据库中的表table1中的字段filed1以"00"打头的数据导出

  exp system/manager@TEST file=d:\daochu.dmp tables=(table1) query=\" where filed1 like '00%'\"

  上面是常用的导出,对于压缩我不太在意,用winzip把dmp文件可以很好的压缩。

  不过在上面命令后面 加上 compress=y 就可以了

  

二、数据的导入

  1、将D:\daochu.dmp 中的数据导入 TEST数据库中。

  imp system/manager@TEST file=d:\daochu.dmp

  上面可能有点问题,因为有的表已经存在,然后它就报错,对该表就不进行导入。

  在后面加上 ignore=y 就可以了。

  2 将d:\daochu.dmp中的表table1 导入

  imp system/manager@TEST file=d:\daochu.dmp tables=(table1)

  基本上上面的导入导出够用了。不少情况我是将表彻底删除,然后导入。

  

注意:

  你要有足够的权限,权限不够它会提示你。

  数据库是可以连上的,用tnsping TEST 来判断数据库TEST能否连上。
