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 get 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.


Requirement 


1) Fix SqlServer Restore Database Error.
2) Alter database in Single User mode to Multi User mode.

Implementation


To, fix this error and alter database in single user mode to multi-user mode I wrote 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 shown below. 
USE master;
Now, I will show you full SQL statement/Query/Solution to fix this error.
USE master;
GO
ALTER DATABASE YourDatabaseName
SET SINGLE_USER
WITH ROLLBACK IMMEDIATE;
ALTER DATABASE YourDatabaseName
SET MULTI_USER;
GO
If analyzed then first I connected to database “master” and the 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 window that you opened, I trying to say that close all the windows you opened for New Query and also change user default database to the master database.
