Hi, Apologies if I am being incredibly stupid, but I just can't seem to get this to work for me. I have a function that validates a web session is still active, so my code looks something like this : BEGIN perform app_security.cleanSessionTable(p_forcedTimeout,p_sessionTimeout); SAVEPOINT sp_cleanedSessionTable; select * into strict v_row from app_security.app_val_session_vw where session_id=p_session_id and session_ip=p_client_ip and session_user_agent=p_user_agent; update app_security.app_sessions set session_lastactive=v_now where session_id=p_session_id; etc. etc. END app_security.cleanSessionTable works beautifully on its on, i.e. give TTL values and it deletes the appropriate roles from the session table etc. However, when used in conjunction with the broader validateSession function, whatever cleanSessionTable does gets rolledback because obviously the select/update statements don't work because cleanSession table has deleted the expired session ? As you can see, I've tried adding a savepoint, but this seems to have no effect ? The autorollback still re-instates the expired session. Help !
