Hello all!
Example trigger:
CREATE OR REPLACE TRIGGER dodaj_prispevek_trigger BEFORE INSERT ON PRISPEVKI
FOR EACH ROW
DECLARE
st_prispevkov NUMBER;
BEGIN
SELECT COUNT(IDPRISPEVKA)
INTO st_prispevkov
FROM PRISPEVKI
UPDATE ODBOR
SET IDCLANA = !!! HERE I NEED A RADNOM INTEGER IN INTERVAL [1, count(IDCLANA)] !!!
....
I googled but didn't find what i was lookin' for :\
Can anybody help?
Thanks!

If we had found a solution for you, everyone would benefit because we would post the answer. To be courteous, you should too...

Sorry, i thought this was to "easy"..

Anyway here is the whole trigger:

CREATE OR REPLACE TRIGGER dodaj_prispevek_trigger AFTER INSERT ON PRISPEVKI

FOR EACH ROW

DECLARE

st_prispevka NUMBER;

st_odobritve NUMBER;

max_clan NUMBER;

st_clana NUMBER;

BEGIN

-- dobimo id vstavljenega prispevka

st_prispevka := :new.IDPRISPEVKA;

-- izracunamo nov id odobritve

SELECT MAX(IDODOBRITEV)

INTO st_odobritve

FROM ODOBRITVE;

st_odobritve := st_odobritve + 1;

SELECT MAX(IDCLANA)

INTO max_clan

FROM ODBORI;

-- nakljucno izberemo clana odbora

SELECT dbms_random.value(1, max_clan) num

INTO st_clana

FROM DUAL;

-- vstavimo odobritev

INSERT INTO ODOBRITVE (IDODOBRITEV, PRIS_IDPRISPEVKA,

ODB_IDCLANA) VALUES (st_odobritve, st_prispevka, st_clana);

END;

/

Bold is what i was lookin for 😉
