Unable to drop database in SQL Server 2012

问题

I have created a sample database earlier and now I want to delete that database, but it is not getting deleted. I searched online but I didn't find any solution which is working.

Using T-SQL, I tried:

USE [Sample]

ALTER DATABASE [Sample]
SET SINGLE_USER
WITH ROLLBACK IMMEDIATE;
GO

DROP DATABASE [Sample]

Using the GUI, I am getting this below error:

I closed existing connection then also this is happening and this is my local machine. Please help me here!

Close your SSMS , open a new instance and then try the following, Copy paste the whole thing into a new query window and execute at once:

USE [master];            
GO

ALTER DATABASE [Sample]   --<-- go back into Multi-user mode
SET MULTI_USER;
GO

ALTER DATABASE [Sample]   --<-- Will disconnect everyone 1st
SET SINGLE_USER              -- and will leave the database in single user mode
WITH ROLLBACK IMMEDIATE;
GO

USE [Sample];                -- quickly grab that single connection before any 
GO                           -- other process does

USE [master];                -- Connect to master db,  connection
GO                           -- This also means disconnect Sample DB 

DROP DATABASE [Sample]       -- At this point there should be no active connections
GO                           -- to this database and can be dropped

Another way to delete the Database (without coding)

In Microsoft SQL Server Management Studio, Right-click the Database that you want to delete (In your case, Sample Database) and then Select Properties.
Select the 'Options' Page.
Under the other option, Find the 'Restrict user' option under 'State'.
Change it value MULTI_USER to SINGLE_USER
Then Press Okay and Try again (Or right-click the database again and click Delete)

Use this Code should help.

ALTER DATABASE [dbname]
SET SINGLE_USER --or RESTRICTED_USER
WITH ROLLBACK IMMEDIATE;
GO
DROP DATABASE [dbname];
GO
