expdp和impdp的应用-高版本通过dblink导入到低版本

今天接到要进行数据库用户的部分数据迁移需求，需求如下

IMP、WO、INSA开头的表只要结构，不要数据

B、TEMP、TMP开头的表不用导

其他表需要导出数据和表结构，同时要求导出此用户下的所有其他对象，如：procedure,sequence等

源数据库在远程主机内，我想到的方法是先通过dblink导入到本地 再将dmp文件传输到目标数据库本机下的directory目录下

1、本地数据库和目标数据库的版本和字符集

查看版本：select * from v$version；　　

本地-Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production

目标：Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Prod

2 、在本地数据库创建database link

create database link dblink73 connect to inas30 identified by inas30 using ‘’orcl01‘’;

3、创建directory--我这里用本地的system用户导出

--我这里用本地的system用户导出

sqlplus / as sysdba

create directory dir as 'F:';

grant all on directory dir to system;

创建目标数据库用户--已有的话就不用创建

create user inas_30 identified by inas_30 default tablespace inas temporary tablespace temp;

grant connect,resource,unlimited tablespace to inas_30;

create directory dir as 'F:';

grant all on directory DUMP_INAS30_73 to inas30_73;

4、筛选需要导出数据的表

---筛选表
select a.TABLE_NAME,a.TABLESPACE_NAME from user_tables a
minus
select b.TABLE_NAME,b.TABLESPACE_NAME from user_tables b where b.TABLE_NAME like 'IMP%'
minus
select c.TABLE_NAME,c.TABLESPACE_NAME from user_tables c where c.TABLE_NAME like 'WO%'
minus
select d.TABLE_NAME,d.TABLESPACE_NAME from user_tables d where d.TABLE_NAME like 'INSA%'
minus
select e.TABLE_NAME,e.TABLESPACE_NAME from user_tables e where e.TABLE_NAME like 'B%'
minus
select f.TABLE_NAME,f.TABLESPACE_NAME from user_tables f where f.TABLE_NAME like 'TEMP%'
minus
select g.TABLE_NAME,g.TABLESPACE_NAME from user_tables g where g.TABLE_NAME like 'TMP%'
minus
select h.TABLE_NAME,h.TABLESPACE_NAME from user_tables h where regexp_like (h.TABLE_NAME,'[[:digit:]]+$')
minus
select h.TABLE_NAME,h.TABLESPACE_NAME from user_tables h where regexp_like (h.TABLE_NAME,'[_][J]{0,2}$')

---导入对象的数据结构
expdp system/123@orcl dumpfile=inas30_1112.dmp logfile=inas30_1112.log directory=dir schemas=inas30 network_link=dblink73 content=metadata_only version=10.2.0.1.0
impdp inas30_73/inas30_73 dumpfile=inas30_1112.dmp logfile=inas30_1112.log directory=DUMP_INAS30_73 remap_schema=inas30:inas30_73 table_exists_action=replace

----删除不用的数据表
declare
cursor cur_ddl is select e.TABLE_NAME,e.TABLESPACE_NAME from user_tables e where e.TABLE_NAME like 'B%'
union
select f.TABLE_NAME,f.TABLESPACE_NAME from user_tables f where f.TABLE_NAME like 'TEMP%'
union
select g.TABLE_NAME,g.TABLESPACE_NAME from user_tables g where g.TABLE_NAME like 'TMP%';

begin
for cur_d in cur_ddl loop
execute immediate 'drop table '||cur_d.TABLE_NAME||'';
end loop;
end;

---导出导入数据表数据
