how to see queries which executed by MC?
any table or log will have this details?
In vsql, you can query v_internal.dc_requests_issued where client_label='MC'.
In MC, you can go to MC Settings -> Monitoring -> Uncheck 'hide MC queries', and this will display MC queries in the MC as well.
Hope that helps.
