SQL Server数据库任务，分离，备份和恢复

Question

我通过vb.net代码附加我的数据库。

现在我请求帮助为以下几点：

1. 如何使用代码（uid=sa, pwd=abc123）分离呢？
2. 如何备份？
3. 如何恢复备份？

请注意，我想要做的这一切用vb.net代码

非常感谢。

Answer 1

备份：

USE AdventureWorks2008R2; 
GO 
BACKUP DATABASE AdventureWorks2008R2 
TO DISK = 'Z:\SQLServerBackups\AdventureWorks2008R2.Bak' 
    WITH FORMAT, 
     MEDIANAME = 'Z_SQLServerBackups', 
     NAME = 'Full Backup of AdventureWorks2008R2'; 
GO 

还原：

----Put database into single user mode (terminates open connections - else restore fails) 
ALTER DATABASE YourDB 
SET SINGLE_USER WITH 
ROLLBACK IMMEDIATE 


RESTORE DATABASE YourDB 
FROM DISK = 'D:\temp\YourDB.bak' 
WITH REPLACE 
,MOVE 'YourDB_Data' TO 'C:\Program Files\Microsoft SQL Server\MSSQL\Data\YourDB_Data.mdf' 
,MOVE 'YourDB_Log' TO 'C:\Program Files\Microsoft SQL Server\MSSQL\Data\YourDB_Data.ldf' 


ALTER DATABASE YourDB SET MULTI_USER 
GO 

分离：

EXEC master.dbo.sp_detach_db @dbname = N'AdventureWorks', 
@keepfulltextindexfile = N'true' 
GO 

附：

EXEC master.dbo.sp_attach_db @dbname = N'AdventureWorks2008R2', 
    @filename1 = N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\Data\AdventureWorks2008R2_Data.mdf', 
    @filename2 = N'C:\Program Files\Microsoft SQL Server\MSSQL10_50.MSSQLSERVER\MSSQL\Data\AdventureWorks2008R2_log.ldf';
