When detail_comments in the testable is inserted or updated too then I want it
to update the various_comments column which is in the same table (testtable). 
What would be the most efficient way to write the trigger to do this?   

CREATE OR REPLACE TRIGGER ADD_TO_TESTTABLE
AFTER INSERT OR UPDATE ON TESTTABLE
FOR EACH ROW
?????

UPDATE :NEW.VARIOUS_COMMENTS
..???????
