Re: WebDB - Form contents in PL/SQL code

If I understand your question correctly, there are probably a couple of ways to do this. The first would be to use a trigger that fires on insert into a table, looking something like this:

CREATE OR REPLACE TRIGGER before_blah
BEFORE INSERT OR UPDATE
ON Blah
REFERENCING OLD AS OLD NEW AS NEW
FOR EACH ROW
begin

    if :new.blah_id = .... then
    end if;
   Exception
    when ... then

    end;
end;

and so on. Raise an exception if the data doesn't validate and continue from there. Another similar way is to control any inserts/updates by using a function or procedure. This is basically the same thing except that you are calling the program explicity.

create or repalce procedure insert_blah (pBlah_ID IN number) is

begin

    if pBlah_ID = whatever then

        insert into blah(id) values(whatever);     else

        raise blah_exception;
    end if;
end;
/

or something like that.
