常用数据库的备份与恢复的方法

总结下各个数据库的 备份与恢复的方法 （有待补充）

---------------------Oracle------------------------

备份：

exp user/password@orcl file='/app/2012.dmp'

恢复：

imp user/password@orcl fromuser=ufidanc touser=pm file='/app/2012.dmp'

------------Ms sqlserver--------------------

备份

backup database dbname to disk='/app/2012.bak'

恢复

restore database dbname2 from disk='/app/2012.bak'

导入文本文件

EXEC master..xp_cmdshell 'bcp "dbname..tablename" in c:\DT.txt -c -Sservername -Usa -Ppassword'

导出文本文件

EXEC master..xp_cmdshell 'bcp "dbname..tablename" out c:\DT.txt -c -Sservername -Usa -Ppassword'

----------------MySql------------------

备份:mysqldump -u root -ppassword dmname > '/app/2012.sql'

还原:mysql -u root -ppassword dbname < '/app/2012.sql'

导出表 : mysqldump -u root -ppassword dmname tablename >'/app/2012.sql'

还原表 mysql -u root -ppassword dmname tablename < '/app/2012.sql'

导入文本文件

load data infile '/app/2012.dat' into table tb_name FIELDS TERMINATED BY '|';

导出文本文件

select * from tb_name into outfile '/app/2012.dat' fields terminated by '|';

-------------------------DB2--------------------------

导出表结构

db2look -d dbname -e -o db2look.sql

然后导出源数据库DB2数据

db2move dbname export –u user –p password

目标数据库

db2 -tvf db2look.sql

db2move dbname import

------------------------Sybase--------------------------

备份数据：

Dump database dbname to '/app/2012.dmp'

恢复数据：

Load database dbname2 from '/app/2012.dmp'

online database dbname2

导出表结构

ddlgen –Usa –Ppassword –Ddbname –Sxxx:port –Ooutput_file

导出数据

bcp dbname..tablename out '/app/2012.dmp' -Sservername -Uname -–Ppassword

导入数据

bcp dbname..tablename in '/app/2012.dmp' -Sservername -Uname -–Ppassword
