使用数据泵将指定的表和序列还原到一个新的schema下

使用数据泵将指定的表和序列还原到一个新的schema下

 

 

 

先创建测试users

-- Create the user

create user SCOTT

default tablespace USERS

temporary tablespace TEMP

profile DEFAULT

password expire

account lock;

-- Grant/Revoke role privileges

grant connect to SCOTT;

grant resource to SCOTT;

-- Grant/Revoke system privileges

grant unlimited tablespace to SCOTT;

 

alter user scott identified by scott

 

 

 

 

-- Create the user

create user hr identified by hr

default tablespace USERS

temporary tablespace TEMP

profile DEFAULT

password expire

account lock;

-- Grant/Revoke role privileges

grant connect to hr;

grant resource to hr;

-- Grant/Revoke system privileges

grant unlimited tablespace to hr;

 

 

 

查看scott下的对象信息

导出Scott

expdp system/oracle directory=expdp_dump dumpfile=expdp_scott_1017$rq.dmp logfile=expdp_scott_1017$rq.log schemas=scott;

导入指定表

 

测试1:使用tables

 

将Scott下的是TA1,TA2,TA3导入到hr下:

 

impdp system/oracle directory=expdp_dump dumpfile=expdp_scott_1017.dmp logfile=impdp_scott_1017.log remap_schema=scott:hr tables=scott.TA1,scott.TA2,scott.TA3;

清除导入hr的对象

测试2:使用include

这种导入会提示ORA-31655:no data or metadata objects selected for job

无法导入表,需要测试1的tables导入

 

 

将Scott下的是TA1导入到hr下:

 

impdp system/oracle directory=expdp_dump dumpfile=expdp_scott_1017.dmp logfile=impdp_scott_1017.log remap_schema=scott:hr include=TABLE:\"=\‘scott.ta1\‘\";

将Scott下的是TA1,TA2,TA3导入到hr下:

 

impdp system/oracle directory=expdp_dump dumpfile=expdp_scott_1017.dmp logfile=impdp_scott_1017.log remap_schema=scott:hr include=TABLE:\"in \(\‘TA1\‘,\‘TA2\‘,\‘TA3\‘\)\";

导入指定序列

要导入制定列需要使用include,而且需要使用转义字符"\"

 

 

将Scott下的是SEQ_TA1_ID导入到hr下:

 

impdp system/oracle directory=expdp_dump dumpfile=expdp_scott_1017.dmp logfile=impdp_scott_1017.log remap_schema=scott:hr include=SEQUENCE:\"in \(\‘SEQ_TA1_ID\‘\)\";

技术分享

 

 

将Scott下的是SEQ_TA2_ID,SEQ_TA3_ID导入到hr下:

 

impdp system/oracle directory=expdp_dump dumpfile=expdp_scott_1017.dmp logfile=impdp_scott_1017.log remap_schema=scott:hr include=SEQUENCE:\"in \(\‘SEQ_TA2_ID\‘,\‘SEQ_TA3_ID\‘\)\";

查看两次导入的对象,都成功

将Scott下的所有序列导入到hr下:

 

impdp system/oracle directory=expdp_dump dumpfile=expdp_scott_1017.dmp logfile=impdp_scott_1017.log remap_schema=scott:hr include=SEQUENCE;

当导入的对象指定前缀是也无法导入

impdp system/oracle directory=expdp_dump dumpfile=expdp_scott_1017.dmp logfile=impdp_scott_1017.log remap_schema=scott:hr include=SEQUENCE:\"in \(\‘scott.SEQ_TA1_ID\‘\)\";

下面尝试将表和序列一起导入,但是都不成功,只能导入序列,所以目前分开导入

 

impdp system/oracle directory=expdp_dump dumpfile=expdp_scott_1017.dmp logfile=impdp_scott_1017.log remap_schema=scott:hr include=SEQUENCE:\"in \(\‘SEQ_TA2_ID\‘,\‘SEQ_TA3_ID\‘\)\" tables=scott.TA1,scott.TA2,scott.TA3;

impdp system/oracle directory=expdp_dump dumpfile=expdp_scott_1017.dmp logfile=impdp_scott_1017.log remap_schema=scott:hr tables=scott.TA1,scott.TA2,scott.TA3 include=SEQUENCE:\"in \(\‘SEQ_TA2_ID\‘,\‘SEQ_TA3_ID\‘\)\";
