Sql Server无法恢复数据库，提示正在被使用

今天尝试恢复(restore)SQL Server数据库，遇到如下问题

考虑两种解决方法
1. 找到所有的连接，并kill他们
2. 将database offline（同时所有链接将被关闭），然后重新online再恢复数据库
方法一

declare @sql as varchar(20), @spid as int

select @spid = min(spid) from master..sysprocesses where dbid = db_id('<database_name>') and spid != @@spid while (@spid is not null) begin print 'Killing process ' + cast(@spid as varchar) + ' ...' set @sql = 'kill ' + cast(@spid as varchar) exec (@sql) select @spid = min(spid) from master..sysprocesses where dbid = db_id('<database_name>') and spid != @@spid end print 'Process completed...'

方法二

alter database database_name set offline with rollback immediate alter database database_name set online go
