After executing this query on master db ,it is giving me all running process on all databases, is there any query which will kill all process running on a database .
USE
Master
GO
SELECT
SPID,DBID FROM SYSPROCESSES
WHERE
DBID NOT IN (1,2,3,4) AND SPID >50 AND SPID<> @@spid
If you want to force every other connection to disconnect, and you have suitable permissions, you can bounce the database in and out of single user mode:
alter database current set single_user with rollback immediate;
go
alter database current set multi_user;
go
Any other connection to the same database will be terminated.
