我正在尝试还原sql Server 2008备份,并收到以下错误：
RESTORE cannot process database because it is in use by this session.
ADDITIONAL INFORMATION:
System.Data.sqlClient.sqlError: RESTORE cannot process database ‘database_name’ because it is in use by this session. It is recommended that the master database be used when performing this operation. (Microsoft.sqlServer.Smo)
知道什么是错的吗？
