DROP SERVICE (Transact-SQL)
Drops an existing service.
DROP SERVICE service_name [ ; ]
The name of the service to drop. Server, database, and schema names cannot be specified.
You cannot drop a service if any conversation priorities refer to it.
Dropping a service deletes all messages for the service from the queue that the service uses. Service Broker sends an error to the remote side of any open conversations that use the service.
Permission for dropping a service defaults to the owner of the service, members of the db_ddladmin or db_owner fixed database roles, and members of the sysadmin fixed server role.
The following example drops the service //Adventure-Works.com/Expenses.
DROP SERVICE [//Adventure-Works.com/Expenses] ;
