Question

I am attaching My DB through vb.net code.

Now I request help for the following:

1. How to detach it using code (uid=sa, pwd=abc123)?
2. How to take backup?
3. How to restore backup?

Please note I want to do it all using vb.net code

Thanks a lot.

Answer 1

Backup:

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

Restore:

----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

Detach:

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

Attach:

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';
