The tail of the log for the database "DBName" has not been backed up

Question

I tried to restore a database using the following query:

ALTER DATABASE [DatabaseName] SET Single_User WITH Rollback Immediate GO RESTORE DATABASE DatabaseName FROM DISK = 'C:\DBName-Full Database Backup' ALTER DATABASE [DatabaseName] SET Multi_User GO 

but instead of restoring the database, I am getting this error:

Msg 3159, Level 16, State 1, Line 2

The tail of the log for the database "DatabaseName" has not been backed up. Use BACKUP LOG WITH NORECOVERY to backup the log if it contains work you do not want to lose. Use the WITH REPLACE or WITH STOPAT clause of the RESTORE statement to just overwrite the contents of the log. Msg 3013, Level 16, State 1, Line 2 RESTORE DATABASE is terminating abnormally.

Answer 1

The error message you are getting tells you exactly what you need to do if you don't care about the existing database or log.

RESTORE DATABASE DAtabaseName FROM DISK = 'C:\DBName-Full Database Backup'  WITH REPLACE 

In SQL Server Management Studio (Tasks > Restore), you can add the WITH REPLACE option by opening the page "Options" on the left side and ticking "Overwrite the existing database".
