导读：expdp tjxtcgs/IP69# [email?protected] dumpfile=‘SCHEMAS_TJXTCGS_FILE%date:~,4%-%date:~5,2%-%date:~8,2%.dmp‘ logfile=‘PM_NOFILE%date:~,2%.log‘ SCHEMAS=TJXTCGS 1.导出部分表： exp tjXXXXs/0000 file=E:oracleoradataorcldtj_2010_2005_dm0

expdp tjxtcgs/IP69# [email?protected] dumpfile=‘SCHEMAS_TJXTCGS_FILE%date:~,4%-%date:~5,2%-%date:~8,2%.dmp‘ logfile=‘PM_NOFILE%date:~,2%.log‘ SCHEMAS=TJXTCGS

1.导出部分表：

exp tjXXXXs/0000 file=E:oracleoradataorcldtj_2010_2005_dm001.dmp tables=dtj_2005_dm001,dtj_2006_dm001,dtj_2007_dm001,dtj_2008_dm001,dtj_2009_dm001,dtj_20010_dm001

xxxxxxxxxx

1 ? 1

exp tjXXXXs/0000 file=E:oracleoradataorcldtj_2010_2005_dm001.dmp tables=dtj_2005_dm001,dtj_2006_dm001,dtj_2007_dm001,dtj_2008_dm001,dtj_2009_dm001,dtj_20010_dm001

（1）表方式，将指定表的数据导出/导入。
导出：
导出一张或几张表：

代码?

exp user/pwd file=/dir/xxx.dmp log=xxx.log tables=table1,table2?

exp user/pwd file=/dir/xxx.dmp log=xxx.log tables=table1,table2

xxxxxxxxxx

3 ? 1

exp user/pwd file=/dir/xxx.dmp log=xxx.log tables=table1,table2?

exp user/pwd file=/dir/xxx.dmp log=xxx.log tables=table1,table2

如果是分区表

代码?

exp user/pwd file=/dir/xxx.dmp log=xxx.log tables=table1:tablespaces1,table2:tablespaces2?

 exp user/pwd file=/dir/xxx.dmp log=xxx.log tables=table1:tablespaces1,table2:tablespaces2

xxxxxxxxxx

3 ? 1

 exp user/pwd file=/dir/xxx.dmp log=xxx.log tables=table1:tablespaces1,table2:tablespaces2?

 exp user/pwd file=/dir/xxx.dmp log=xxx.log tables=table1:tablespaces1,table2:tablespaces2

导出某张表的部分数据

代码?

$ exp user/pwd file=/dir/xxx.dmp log=xxx.log tables=table1 query=”where col1=’…’???
and col2 &;…”?

$ exp user/pwd file=/dir/xxx.dmp log=xxx.log tables=table1 query=”where col1=’…’
and col2 &;…”

xxxxxxxxxx

5 ? 1

$ exp user/pwd file=/dir/xxx.dmp log=xxx.log tables=table1 query=”where col1=’…’???

and col2 <…”?

$ exp user/pwd file=/dir/xxx.dmp log=xxx.log tables=table1 query=”where col1=’…’

and col2 <…”

导入：
导入一张或几张表

代码?

$? imp? user/pwd? file=/dir/xxx.dmp? log=xxx.log? tables=table1,table2? fromuser=dbuser touser=dbuser2 commit=y ignore=y?

$? imp? user/pwd? file=/dir/xxx.dmp? log=xxx.log? tables=table1,table2? fromuser=dbuser touser=dbuser2 commit=y ignore=y

xxxxxxxxxx

3 ? 1

$? imp? user/pwd? file=/dir/xxx.dmp? log=xxx.log? tables=table1,table2? fromuser=dbuser touser=dbuser2 commit=y ignore=y?

$? imp? user/pwd? file=/dir/xxx.dmp? log=xxx.log? tables=table1,table2? fromuser=dbuser touser=dbuser2 commit=y ignore=y

代码?

$? imp? user/pwd? file=/dir/xxx.dmp? log=xxx.log? tables=table1:tablespaces1,table2:tablespaces2? fromuser=dbuser touser=dbuser2 commit=y ignore=y?

$? imp? user/pwd? file=/dir/xxx.dmp? log=xxx.log? tables=table1:tablespaces1,table2:tablespaces2? fromuser=dbuser touser=dbuser2 commit=y ignore=y

xxxxxxxxxx

3 ? 1

$? imp? user/pwd? file=/dir/xxx.dmp? log=xxx.log? tables=table1:tablespaces1,table2:tablespaces2? fromuser=dbuser touser=dbuser2 commit=y ignore=y?

$? imp? user/pwd? file=/dir/xxx.dmp? log=xxx.log? tables=table1:tablespaces1,table2:tablespaces2? fromuser=dbuser touser=dbuser2 commit=y ignore=y

（2）用户方式，将指定用户的所有对象及数据导出/导入。
导出：

代码?

$ exp user/pwd file=/dir/xxx.dmp log=xxx.log owner=(xx,yy)?

$ exp user/pwd file=/dir/xxx.dmp log=xxx.log owner=(xx,yy)

xxxxxxxxxx

3 ? 1

$ exp user/pwd file=/dir/xxx.dmp log=xxx.log owner=(xx,yy)?

$ exp user/pwd file=/dir/xxx.dmp log=xxx.log owner=(xx,yy)

只导出数据对象，不导出数据? (rows=n )

$ exp user/pwd file=/dir/xxx.dmp log=xxx.log owner=user rows=n

xxxxxxxxxx

1 ? 1

$ exp user/pwd file=/dir/xxx.dmp log=xxx.log owner=user rows=n

导入：

代码?

imp? user/pwd? file=/dir/xxx.dmp? log=xxx.log? fromuser=dbuser? touser=dbuser2???

imp? user/pwd? file=/dir/xxx.dmp? log=xxx.log? fromuser=dbuser? touser=dbuser2

xxxxxxxxxx

3 ? 1

imp? user/pwd? file=/dir/xxx.dmp? log=xxx.log? fromuser=dbuser? touser=dbuser2???

imp? user/pwd? file=/dir/xxx.dmp? log=xxx.log? fromuser=dbuser? touser=dbuser2

（3）全库方式，将数据库中的所有对象导出/导入导出：

代码?

exp user/pwd file=/dir/xxx.dmp log=xxx.log full=ycommit=y ignore=y?

exp user/pwd file=/dir/xxx.dmp log=xxx.log full=ycommit=y ignore=y

x ? 1

exp user/pwd file=/dir/xxx.dmp log=xxx.log full=ycommit=y ignore=y?

exp user/pwd file=/dir/xxx.dmp log=xxx.log full=ycommit=y ignore=y

导入：

代码?

imp user/pwd file=/dir/xxx.dmp log=xxx.log fromuser=dbuser touser=dbuser2

? 1

imp user/pwd file=/dir/xxx.dmp log=xxx.log fromuser=dbuser touser=dbuser2
