Question

How to insert a value from sequence in Bussiness Components?
I would like to do it, but without a triger that would do it before insert.
I know that there is a type DBSequence in BC where you can insert a sequence name but it does not work when I type there my sequence name.
Do you now how to fix that problem?

Answer 1

The newer way to do it is to make the type DBSequence and enter the name of the Sequence object in the sequence field. It must match the same name of the sequence object in the database. Next, you have to create a before insert for each row trigger on the table. Basically, something like this:
CREATE OR REPLACE TRIGGER TGB_THEME_SEQ
BEFORE INSERT ON THEME
FOR EACH ROW
DECLARE
BEGIN
-- Assign the id from the sequence if null
     IF( :new.theme_id IS NULL ) THEN
          SELECT THEME_ID_SEQ.nextval
          INTO :new.theme_id
          FROM dual;
     END IF;
END;
In the above example, THEME_ID_SEQ is the seuence object name in the database. If you have the name right but it still fails, then the user you are logging in as probably doesn't have access to the sequence in the database.
Hope this helps.
