use master
go

declare @dbname sysname
set @dbname = 'databasename' --这个是要删除的数据库库名

declare @s nvarchar(1000)
declare tb cursor local
for
select s = 'kill ' + cast(spid as varchar)
from master..sysprocesses
where dbid = db_id(@dbname)

open tb 
fetch next from tb into @s
while @@fetch_status = 0
begin
exec (@s)
fetch next from tb into @s
end
close tb
deallocate tb

exec ('drop database [' + @dbname + ']')
