Hoe Key Value als resultatenset uit de Oracle JSON-kolom te halen met JSON_TABLE

Probeer dit:

declare
  jo JSON_OBJECT_T;
  i  NUMBER;
  keys JSON_KEY_LIST;
  CURSOR c_json IS
     SELECT myJsonCol FROM mytable;
begin
  FOR rec IN c_json
  LOOP
     jo := JSON_OBJECT_T.parse(rec.myJsonCol);
     keys := jo.get_keys;
     dbms_output.put_line('KEY VAL');
     FOR i in 1..keys.COUNT
     LOOP
        dbms_output.put_line(keys(i) || ' ' || jo.get_Number(keys(i)));
     END LOOP;
   END LOOP;
END;
