), recent_sessions as 
         where login_time > (select max(measure_time) from EXA_STATISTICS.EXA_SYSTEM_EVENTS where event_type='STARTUP')
), logged_in_sessions as 
        (select * from recent_sessions
         where (select min(ts) from target_time) between login_time and coalesce(logout_time, current_timestamp)
), running_queries as 
        (select * from EXA_STATISTICS.EXA_DBA_AUDIT_SQL
         where (select min(ts) from target_time) between start_time and stop_time
), active_sessions as
        (select L.login_time, L.logout_time, L.user_name,L.client,L.driver,L.encrypted,L.host,L.os_user,L.os_name, 
        from logged_in_sessions L left join running_queries S on (L.session_id=S.session_id)
select * from active_sessions;
