数据库备份与还原

--返回由备份集内包含的数据库和日志文件列表组成的结果集。
--主要获得逻辑文件名
USE master
RESTORE FILELISTONLY
FROM DISK = 'g:\back.Bak'
Go
************************************************

利用bak恢复数据库，强制还原(REPLACE)
STATS = 10 每完成10%显示一条记录
DBTest和DBTest_log是上面g:\back.Bak里的逻辑文件
*/
USE master
RESTORE DATABASE DB
   FROM DISK = 'g:\back.Bak'
   WITH MOVE 'DBTest' TO 'E:\Program Files\Microsoft SQL Server2005\Data\DB.mdf',
   MOVE 'DBTest_log' TO 'E:\Program Files\Microsoft SQL Server2005\Data\DB_log.ldf',
STATS = 10, REPLACE
GO
