Import/Export工具可以实现: (1)获取数据库中对象的创建脚本 (2)备份数据(逻辑备份,小规模数据库效率高) (3)跨平台、跨版本的迁移数据 (4)在多个数据库之间通过传输表空间特性快速复制数据 Export: 首先确保用户有权利导入导出数据,以SYS身份

Import/Export工具可以实现:
(1)获取数据库中对象的创建脚本
(2)备份数据(逻辑备份,小规模数据库效率高)
(3)跨平台、跨版本的迁移数据
(4)在多个数据库之间通过传输表空间特性快速复制数据

Export:

首先确保用户有权利导入导出数据,以SYS身份授权给将要执行导出的用户
SQL> show user
USER is "SYS"
SQL> grant exp_full_database to scott;

Grant succeeded.

SQL> grant imp_full_database to scott;

Grant succeeded.

1.导出表中的某些记录:
背景:
SQL> select * from scott.test;

ID
----------
1
2
3
4
5

导出id 测试:
[oracle@linux5 ~]$ exp scott/oracle tables=test query=\"where ID\

2.导出某个SCHEMA下的某些表
背景:
SQL> select count(*) from scott.emp;

COUNT(*)
----------
14

SQL> select count(*) from scott.dept;

COUNT(*)
