To mask stored procedures, Dynamic Data Masking dynamically creates tables and temporary stored procedures in a temporary database that you define in the accelerator security rules. After the Rule Engine applies masking rules to the SQL statement, it creates a temporary stored procedure and sends the request to the tables in the temporary database.

You can create a cleanup scheduled task on Windows or a cleanup Cronjob on Linux to drop the tables and stored procedures. If you do not create the job, you must periodically manually drop the tables and stored procedures in the temporary database.
