In the process of using the Sybase database, we often encounter a lock on the Sybase database system, and in most cases the user must log on to the system through the Superuser identity to handle the process. In order to ensure the security of Sybase database system, Superuser password is often in the hands of the database administrator.
When the above situation occurs, if the database administrator is not
