I was trying to do
SELECT employeename, job_id_seq.CURRVAL
FROM employees;
I got an error. Can't i call CURRVAL of a sequence via SELECT like above? Why? I know it would work if i do it on DUMMY table.
Can i use name.CURRVAL via INSERT INTO? Why?

You can do this:
INSERT INTO t_chybar (pk_id, typ_chyby, cislo_debug ,miesto, chyba, datum, uzivatel)
VALUES (T_CHYBAR_ID_SEQ.nextval, v_typ_chyby, n_cislo_debug, v_miesto, v_chyba,sysdate, v_uzivatel);
If you want to use name.CURRVAL then at first it must be initialized by e.g.
select name.NEXTVAL ...;
