How to delete database, error 5030 database can't be locked

Question

I am trying to delete an existing database in SQL Server 2005. My first attempt produced the following error:

5030: The database could not be exclusively

Answer 1

This error normally occurs when your database is in Multi User mode where users are accessing your database or some objects are referring to your database. First you should set the database to single user mode:

ALTER DATABASE dbName
SET SINGLE_USER WITH ROLLBACK IMMEDIATE

Now we will try to delete the database

delete DATABASE ...

Finally set the database to Multiuser mode

ALTER DATABASE dbName
SET MULTI_USER WITH ROLLBACK IMMEDIATE
