“无法删除数据库，因为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 + ']')
