Hello David,
There is way to activate SQL tracing for particular table and also the user history.
You can do this from the SAP HANA Studio with the Administration console, from here we can trace any SQL statement that is going into the database.
For an example if you want to know how many users are logged in and want to know the most expensive Query that is running at specified time you can track them by activating the above traces.
Note: The trace should be Turned off once the required Info is gathered.
Thanks-
Phani.
