In my previous article, I explained how to fix The 'Microsoft.ACE.OLEDB.12.0' Provider Is Not Registered On The Local Machine error, and in this article, I gonna show you another error with a solution and example.


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 )

Requirement 

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

Implementation

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;
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 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.

Summary

This article gives an explanation about how you can fix SQL server database restore error and also show you how you can alter your database mode from single user mode to multiuser mode.
