I am trying to do a SQL Server database restore using this T-SQL code:
----Make Database to single user Mode
ALTER DATABASE xyz
SET SINGLE_USER WITH
ROLLBACK IMMEDIATE
----Restore Database
RESTORE DATABASE xyz
FROM DISK = 'D:\\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Backup\xyz_backup_201204100301.bak'
WITH MOVE 'abc' TO 'D:\\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\xyz.MDF',
MOVE 'abc_log' TO 'E:\\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Data\xyz.LDF'
but while running the above i get the following error:
Msg 5064, Level 16, State 1, Line 1
Changes to the state or options of database 'xyz' cannot be made at this time. The database is in single-user mode, and a user is currently connected to it.
Msg 5069, Level 16, State 1, Line 1
ALTER DATABASE statement failed.
How can I run my restore successfully?
Is restarting the database the only way to solve the problem. Any other suggestions?!

This error does not occur if YOU are the single-user in the database. It only occurs if someone else is in it AND it is ALREADY in single-user mode.
For example, try this:
Note: there are 4 separate batches, and the 4th one doesn't error. You're setting the mode while IN the database, and also setting it a 2nd time. No error.
Assuming you have been given the mandate to restore the DB regardless of what is happening, do an sp_who2 to look for the user who is connected, and KILL the spid. You can then proceed with the RESTORE.
