Multiple destination tables, oracle sequence problems

Question

Hello,
Please look at this sql - there is 2 steps to add data to 2 destination tables:
- step1:
INSERT INTO OBIEKTY (ID_OB, TELEFON, FAX, NR_LOKALU, UWAGI, ULICA, GEOM, NR_BUDYNKU, KOD_POCZTOWY, LISTA_OBIEKTOW, EMAIL, GMINA, NAZWA, WOJEWODZTWO, MIEJSCOWOSC, USUNIETY, POWIAT, JEDNOSTKA_WYJAZDOWA, MIEJSCOWOSC_POCZTY)
VALUES (OB_SEQ.NEXTVAL, null, null, null, null, 'Legionowa', null, '8', '15-099', '0', null, null, 'WSSE w Białymstoku',null , 'Białystok', null, null, '0', null);
-step2:
INSERT INTO ZASOBY (ID_ZAS, UZYT_TWORZACY, UWAGI, UZYT_OST_MODYFIKACJI, DATA_OST_MODYFIKACJI, DYSPONOWALNY, DATA_UTWORZENIA, USUNIETY, ID_SPRZETU, ID_PAT, ID_MAT, ID_INST, ID_KATEGORII, ID_OBIEKT, ID_POZ_SL, ID_OSOBA, IMPORT)
VALUES (ZAS_SEQ.NEXTVAL, 'import', null, null, null, '0', SYSDATE, '0', null, null, null, null, KTZ_SEQ.CURRVAL, OB_SEQ.CURRVAL, (select p.id_poz_sl from pozycje_slownikow p join slowniki s on p.id_slownika=s.id_sl where s.nazwa like 'TYPY_ZASOBOW' and p.kod = 'OB'), null, '1');
There are problems with sequences. As you can see, there is OB_SEQ.NEXTVAL in first step and OB_SEQ.CURRVAL in second step. It's impossible to define multiple destination tables in one interface. But, if I do this in multiple interfaces, OB_SEQ.CURRVAL will be undefined in second interface.
Also, all steps should be performed row by row. So: first step for first row, second step for first row, first step for second row, second step for second row etc. This don't happen if I use multiple interfaces - first step will be performed for all source records and then, second step will be performed for the same records - this is not what I want.
Do you have any tips what is the best way in this case?

Answer 1

Hello,
Unfortunately, problem is not solved still. As you can see, there are 2 sequences, from 2 not joined tables: KTZ_SEQ.CURRVAL, OB_SEQ.CURRVAL. KTZ_SEQ.CURRVAL is declared here:
insert into KATEGORIE_ZASOBU (ID_KTZ, UZYT_TWORZACY, UZYT_OST_MODYFIKACJI, LOKALIZACJA, DZIEDZICZENIE, DATA_OST_MODYFIKACJI, DATA_UTWORZENIA, DYSPONOWALNA, SYSTEMOWA, WYBIERALNA, OPIS, NAZWA, USUNIETA, ID_KATEGORII1, ID_POZ_SL, IMPORT)
values (KTZ_SEQ.NEXTVAL, 'import', null, '0', '0', null, SYSDATE, '0', '0', '1', null, 'Jednostki WSSE', '0', null, (select p.id_poz_sl from pozycje_slownikow p join slowniki s on p.id_slownika=s.id_sl where s.nazwa like 'TYPY_ZASOBOW' and p.kod = 'OB'), '1');
So, summary:
- there are 2 steps (OB_SEQ.CURRVAL. KTZ_SEQ.CURRVAL) are set
- third step: insert some hardcoded data + OB_SEQ.CURRVAL. KTZ_SEQ.CURRVAL values.
Since KATEGORIE_ZASOBU and OBIEKTY are not joined, I can't add them as datasources in my interfaces (how to create join?) and set CURVAL?
