Server going to Single User mode

Hi guys,

I am having a database which we refresh every night with same back up where it is used for testing purposes. we will refresh the database thorough job. every time it refreshes it goes to single user mode, I should manually go and change the process using following steps:

1) to execute sp_dboption

sp_dboption 'testdb01', 'single user', 'FALSE';
 go

2) to retrieve client session per database

select d.name, d.dbid, spid, login_time, nt_domain, nt_username, loginame
  from sysprocesses p inner join sysdatabases d on p.dbid = d.dbid
 where d.name = 'testdb01'
go

3) kill the particular session

kill 51
go

4)Now I can ‘remove’ the database from Sinlge user mode.

exec sp_dboption 'testdb01', 'single user', 'FALSE'
go

Is there any way to write a query  in which if the session goes to single user mode  kill that session and start the restore process again? can you guys  help in implementing that code.

thanks,

aravind.
