今天在还原数据库的时候,提示"因为数据库正在使用,香港虚拟主机,所以无法获得对数据库的独占访问权",无论我是重启数据库,还是重启计算机,香港服务器租用,都不能解决问题,多番尝试后,终于解决了该问题。现将引发该问题的原因与解决方案写出来,有不对的地方欢迎大家提出来。

引发原因:是因为我在还原数据库的时候,还有其他的用户正在使用数据库,所以就会出现以上提示。

解决办法有三种:

第一种:利用游标循环所有正在使用该数据库的进程,并通过kill命令杀死进程。

declare @dbname varchar(50)
set @dbname='数据库名称'
declare @sql varchar(50)
declare cs_result cursor local for select 'kill '+cast(spid as varchar(50)) from sys.sysprocesses where db_name(dbid)=@dbname 
open cs_result
fetch next from cs_result into @sql
while @@fetch_status=0
begin
    execute(@sql)
    fetch next from cs_result into @sql
end
close cs_result
deallocate cs_result

注意:不要在需要的还原的数据库下执行,建议在master数据库下面执行

第二种:利用SQL语句,断开所有用户链接,并回滚所有事务

ALTER DATABASE [数据库名称] 
SET OFFLINE WITH ROLLBACK IMMEDIATE

注意:不要在需要的还原的数据库下执行,建议在master数据库下面执行

第三种:设置数据库在单用户模式下工作

在需要还原的数据库上右击,香港空间,在右键菜单命令上选择"属性"- >"选项"- >"状态"- >"限制访问"- >"Single"。这是SQLSERVER2005的菜单命令,其它版本请自己查找
