I would like to ask about statements like:
ALTER SESSION SET NLS_DATE_LANGUAGE='Polish';
ALTER SESSION SET NLS_DATE_FORMAT='DD/MM/YYYY';
They worked properly in Oracle Live SQL (i.e. they changed settings for the duration of the session) but they do not change anything in FreeSQL (there is no error after execution of the statement but they do not change the formats). Why is it so? What can be done to change the parameters?
