SELECT session_id, start_time, end_time, domain_name, project_name, user_name,
client_type, slh_license_type
FROM QCSITEADMIN_DB_ALM11.sessions_history, QCSITEADMIN_DB_ALM11.session_license_history
WHERE slh_session_id = session_id
AND slh_license_type = 1
AND TO_DATE (start_time, 'dd/mm/yyyy') = TO_DATE(sysdate,'dd/mm/yyyy')
AND end_time IS NULL
