sqlserver中的库可以像oracle那样导出为dmp文件吗？
各位英雄好汉、是大侠不是大侠的，sqlserver可以像oracle那样导出为dmp文件吗？行的话可否给个demo,谢了！

------解决方案--------------------
--oracle的是dmp文件.
--SQL SERVER是bak(备份文件)
方法:1.使用企业管理器中数据的备份恢复.
2.使用backup database备份数据库(具体例见帮助).
3.使用restore database恢复数据库(具体例见帮助).

备份整个数据库：

BACKUP DATABASE { database_name | @database_name_var }
TO < backup_device > [ ,...n ]
[ WITH
[ BLOCKSIZE = { blocksize | @blocksize_variable } ]
[ [ , ] DESCRIPTION = { 'text ' | @text_variable } ]
[ [ , ] DIFFERENTIAL ]
[ [ , ] EXPIREDATE = { date | @date_var }
| RETAINDAYS = { days | @days_var } ]
[ [ , ] PASSWORD = { password | @password_variable } ]
[ [ , ] FORMAT | NOFORMAT ]
[ [ , ] { INIT | NOINIT } ]
[ [ , ] MEDIADESCRIPTION = { 'text ' | @text_variable } ]
[ [ , ] MEDIANAME = { media_name | @media_name_variable } ]
[ [ , ] MEDIAPASSWORD = { mediapassword | @mediapassword_variable } ]
[ [ , ] NAME = { backup_set_name | @backup_set_name_var } ]
[ [ , ] { NOSKIP | SKIP } ]
[ [ , ] { NOREWIND | REWIND } ]
[ [ , ] { NOUNLOAD | UNLOAD } ]
[ [ , ] RESTART ]
[ [ , ] STATS [ = percentage ] ]
]


还原整个数据库：

RESTORE DATABASE { database_name | @database_name_var }
[ FROM < backup_device > [ ,...n ] ]
[ WITH
[ RESTRICTED_USER ]
[ [ , ] FILE = { file_number | @file_number } ]
[ [ , ] PASSWORD = { password | @password_variable } ]
[ [ , ] MEDIANAME = { media_name | @media_name_variable } ]
[ [ , ] MEDIAPASSWORD = { mediapassword | @mediapassword_variable } ]
[ [ , ] MOVE 'logical_file_name ' TO 'operating_system_file_name ' ]
[ ,...n ]
[ [ , ] KEEP_REPLICATION ]
[ [ , ] { NORECOVERY | RECOVERY | STANDBY = undo_file_name } ]
[ [ , ] { NOREWIND | REWIND } ]
[ [ , ] { NOUNLOAD | UNLOAD } ]
[ [ , ] REPLACE ]
[ [ , ] RESTART ]
[ [ , ] STATS [ = percentage ] ]
]
