如何删除当前正在使用和处于单用户模式的 SQL Server 数据库

Question

我在 SQL Server 2008 上有一个数据库，我想删除它。目前它处于单用户模式并且正在使用中。

select * from sys.sysprocesses

返回

Msg 924, Level 14, State 1, Line 1
Database 'G_MAIN_DE' is already open and can only have one user at a time.

我不知道如何识别我必须杀死的会话。

尝试将其设置为离线

ALTER DATABASE G_MAIN_DE SET OFFLINE WITH ROLLBACK IMMEDIATE

产量

Msg 5064, Level 16, State 1, Line 1
Changes to the state or options of database 'G_MAIN_DE' cannot be made at this time. The database is in single-user mode, and a user is currently connected to it.
Msg 5069, Level 16, State 1, Line 1
ALTER DATABASE statement failed.

Answer 1

要识别当前使用数据库的会话，您可以尝试

SELECT request_session_id
FROM   sys.dm_tran_locks
WHERE  resource_database_id = DB_ID('G_MAIN_DE') 

Answer 2

此内置存储过程显示与数据库的所有连接

exec sp_who2

并且此查询会终止与数据库的连接，例如连接 SPID #53

exec kill 53
