我有一个经常从Visual Studio数据库项目重新部署的开发数据库(通过TFS自动构建)。
有时当我运行我的构建时,我会得到这个错误:
ALTER DATABASE failed because a lock could not be placed on database 'MyDB'. Try again later.
ALTER DATABASE statement failed.
Cannot drop database "MyDB" because it is currently in use.
我试了一下:
ALTER DATABASE MyDB SET RESTRICTED_USER WITH ROLLBACK IMMEDIATE
但我仍然无法删除数据库。(我猜大多数开发人员都有dbo访问权限。)
我可以手动运行SP_WHO并开始终止连接,但我需要在自动构建中自动执行此操作。(虽然这次我的连接是数据库中唯一一个我试图放弃的连接。)
是否有一个脚本可以删除我的数据库,而不管连接的是谁?

更新
适用于MS SQL Server 2012及以上版本
USE [master];
DECLARE @kill varchar(8000) = '';
SELECT @kill = @kill + 'kill ' + CONVERT(varchar(5), session_id) + ';'
FROM sys.dm_exec_sessions
WHERE database_id = db_id('MyDB')
EXEC(@kill);
对于MS SQL Server 2000, 2005, 2008
USE master;
DECLARE @kill varchar(8000); SET @kill = '';
SELECT @kill = @kill + 'kill ' + CONVERT(varchar(5), spid) + ';'
FROM master..sysprocesses
WHERE dbid = db_id('MyDB')
EXEC(@kill);
