帶where查詢條件的expdp/impdp

測試

expdp

1> 建表

1 create table test5 ecology.test5 (id int);

 

2> 插入5條數據

1 insert into ecology.test5 vaules (1);
2 insert into ecology.test5 vaules (2);
3 insert into ecology.test5 vaules (3);
4 insert into ecology.test5 vaules (4);
5 insert into ecology.test5 vaules (5);
6 commit;

 

3> 創建directory 

1 create ditectory mydata as '/data1/expdp';
2 grant read,write on directory mydata to ecology;

 

4> 導出id為1的數據

 1 [oracle@oracle expdp]$ expdp ecology/ecology directory=mydata dumpfile=test5.dmp tables=test5 query='test5:"where id =1"'

impdp

首先導出test5的全部數據（省略）

以下為導出命令

 1 [oracle@oracle expdp]$ impdp ecology/ecology directory=mydata dumpfile=test5-1.dmp tables=test5 content=data_only query='test5:"where id=1"'
