thanks for the reply,

I have just executed the query in SQL Server 2005, it worked fine...but the database connection was broken

-------

Nonqualified transactions are being rolled back. Estimated rollback completion: 100%.

Failed to restart the current database. The current database is switched to master.

RESTORE DATABASE successfully processed 561 pages in 0.350 seconds (13.130 MB/sec).

---------------------

But it failed to start the current database...

Error:

Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: Connection reset by peer: socket write error

Note: How can i use this query in the application?

It is giving the following error

Caused by: com.microsoft.sqlserver.jdbc.SQLServerException: ALTER DATABASE statement not allowed within multi-statement transaction.
