Question

I would like to know how (and by extension if it’s possible) to put SQL Server 2005 in single user mode using SQL statements?

I found these instructions on the MSDN, but alas they require SSMS.

*To set a database to single-user mode

1. In Object Explorer, connect to an instance of the SQL Server 2005 Database Engine, and then expand that instance.
2. Right-click the database to change, and then click Properties.
3. In the Database Properties dialog box, click the Options page.
4. From the Restrict Access option, select Single.
5. If other users are connected to the database, an Open Connections message will appear. To change the property and close all other connections, click Yes.*

Answer 1

The following should work:

ALTER DATABASE [MyDatabase] SET SINGLE_USER WITH NO_WAIT
GO

with

ALTER DATABASE [MyDatabase] SET MULTI_USER WITH NO_WAIT
GO

to set it back to multi-user
