SQL Server Restore Database Error

While you working with SQL Server database sometimes you get some unknown errors during web/software applications. 

Recently, I got the error I am using SQL Server 2008 R2 and based on the client requirement I need to restore a database from a .bak file but while I restore the database using a (.bak) file it always gives an error that the database is in use and gets same error until I restart the SQL Server service and error is something like "Alter Failed for Database MyDatabaseName" and while I go with additional information about the error then I found "ALTER DATABASE statement failed ( Microsoft SQL Server, Error: 5064 )" and other detailed SQL server database restore error information as I show in the screen below.

ALTER DATABASE statement failed ( Microsoft SQL Server, Error: 5064 )


  • Fix SqlServer Restore Database Error.
  • Alter database in Single User mode to Multi-User mode.


To, fix this error and alter the database in single user mode to multi-user mode I wrote the following SQL Statment where you just have to open a query window that is connected to database “master” in SQL Server Management Studio. and to connect "master" database you just have to write the following statement as I have shown below. 

USE master;

Now, I will show you the full SQL statement/Query/Solution to fix this error.

USE master;

If analyzed then first I connected to database “master” and then altered my database as a single user with rollback immediate and then after I altered my database as a multi-user.

NOTE: Make sure that you closed all the connections and query windows that you opened, I trying to say that close all the windows you opened for New Query and also change the user default database to the master database.
