I have to restore production copies of my database daily onto development servers. Since the restore process requires exclusive access to the database, I have come up with this nifty script to silently kill all users connected to the database. This procedure kills all database processes before restoring the database so that the restore process gets exclusive access to the database:
CREATE proc rp_kill_db_processes (@dbname varchar(20)) as Declare @dbid int, @spid int, @str nvarchar(128) select @dbid = dbid from master..sysdatabases where name = @dbname declare spidcurs cursor for select spid from master..sysprocesses where dbid = @dbid open spidcurs fetch next from spidcurs into @spid While @@fetch_status = 0 Begin Select @str = 'Kill '+convert(nvarchar(30),@spid) exec(@str) --print @str fetch next from spidcurs into @spid End Deallocate spidcurs GO
exec rp_kill_db_processes where 'test'
...where test is the name of the database.
Sam B. writes: I have created the procedure successfully, when I check the syntax of the exec line in Query Analyser I get an error near "Where". I have changed the 'test' to reflect the name of my database but still have no success. Please can you help? I must be missing something obvious!
