My Question:

I fill up my first table. After on 2nd table i call PaletKod row. PaletKod row autofill Kilo Row on 2nd table from 1st Table.

But i need when i fill PaletKod to my 2nd table how can i select Paletkod from first table and fill my 3rd table values (Uretici, Urun, Kilo, Kalibre ) ?

With Trigger ?
create trigger tr_au_CkisEks
after update on CkisEks
for each row
update UrunPaketDetay t1, Ckis_Detay t2
set t2.Uretici = t1.Uretici, 
    t2.Urun = t1.Urun, 
    t2.Kilo = t1.Kilo, 
    t2.Kalibre = t1.Kalibre
where t1.PaletKod = NEW.PaletKod
  and t2.PaletKod = NEW.PaletKod;
