帶where查詢條件的expdp/impdp

測試

expdp

1> 建表

create table test5 ecology.test5 (id int);

 

2> 插入5條數據

insert into ecology.test5 vaules (1);

insert into ecology.test5 vaules (2);

insert into ecology.test5 vaules (3);

insert into ecology.test5 vaules (4);

insert into ecology.test5 vaules (5);

commit;

 

3> 建立directory 

create ditectory mydata as '/data1/expdp';

grant read,write on directory mydata to ecology;

 

4> 導出id爲1的數據

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

impdp

首先導出test5的所有數據（省略）

如下爲導出命令

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