SQL is a universal database used by various organizations to manage their application data. In addition, it is a popular choice for DBAs because it is reliable, easy to use, and easy to maintain. The most important task of an administrator in an MS SQL database is to back up and restore the database if necessary. However, when restoring the database, a common error that most DBAs encounter is: “SQL Database Restore Failed”.

Multiple Solutions to Fix SQL Database Restore Failed Issue

Before you begin implementing any of the following methods, make sure that SQL Server and SQL Server Management Studio are installed on your system. After the installation, you can choose the following methods to resolve the error.

Identify Active Users by using sp_who

First, you must disconnect all users when restoring the database using the Close Connection option. However, if you do not want to disconnect users, use the sp_who command to check active users. This is a popular command in SQL Server that helps users find processes and active users using a database.

This command is mostly useful when you don’t want to disconnect users while doing basic tasks on the server.

Restart SSMS Service

You can also disconnect all users by restarting SQL Server using SSMS, the Service Console, Command Line, PowerShell Administration, or SQL Server Configuration Manager. However, this option should only be selected if the above method does not work. Here we discuss the process of restarting the service with the configuration manager.

  1. If you are using Windows Server 2008 or 2003, open the SQL Server Configuration Manager via the following Start >> Programs >> Microsoft SQL Server >> Configuration Tools >> SQL Server Configuration Manager
  2. Now select the SQL Server Services in the left pane of the SQL Server Configuration Manager. The service will appear in the right pane, right click on the SQL Server Services and choose Restart from the context menu.

If there are no other options to restore the database, this is the solution you should choose.

Open SQL Server in Single-user Mode

Another ideal way to disconnect active users from SQL Server without notifying them is to change from multi-user mode to single-user mode. To switch between modes, you need to run the following SQL commands in T-SQL:

USE master;
GO
ALTER DATABASE MayurSampleDB
SET SINGLE_USER
WITH ROLLBACK IMMEDIATE;
GO

Running this command will terminate all existing connections before the database is restored.
