Since I got a new work laptop, I am unable to run queries in SQL Developer and get an output.
I can run the following and I get the "Session Altered" but if I then try and run an query, nothing happens and I don't see an output:
alter session set current_schema = apps;
ALTER SESSION SET NLS_LANGUAGE = AMERICAN;
Does anyone know how to fix this please?
SELECT 1 from dual;
What happens exactly when you run that?
