"没法删除数据库，由于该数据库当前正在使用"问题解决

use master    
go   
     
declare @dbname sysname    
set @dbname = 'BigValuesTest' --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.dbo.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 + ']')
